@@jayarmstrong the epidemic of myopia that develops in children is because as they are growing, they don't receive enough sunlight (2 hours a days of direct sunlight every day). Because of that, the eyeball keeps lengthening. After the person has stopped growing, the amount of sunlight you receive does not affect the growth of the eye anymore. This is also the reason the eyesight settles towards the end of the teen years and they recommend to do LASIK surgery after your eyesight has settles.
I've heard you can also reverse myopia when you're an adult if you pay attention to how much time you spend looking at things up close versus far away, and getting enough sunlight, so it's not just a hopeless case for adults.
@@utubekullanicisi as far as I am aware, you can only reduce the risk of developing myopia by getting enough sunlight. It is most important to get sunlight during your developing years, but some have said to also get enough sunlight in your twenties, I am not 100% certain on the reason why so I won't mention it. But I haven't found any study or article mentioning reversing myopia.
In Sweden, if you work more than 1 hour per day in front of a screen, your employer must pay for eye exams and "terminal glasses" - basically individually adapted reading glasses so your eyes can relax. You intentionally make yourself nearsighted enough that the horizon focal distance moves to the edge of your desk. I wish you would have mentioned reading glasses as a good option for those who do not have the money or space to work in front of a huge TV. 😊
Would love to understand this. So these terminal glasses make your eyes work harder to see distant objects? What exactly moves to which edge of the desk?
@@jayarmstrong I recon they block blue light and glare commonly associated with eye strain. if you have glasses consider getting a pair with glare/blue light reduction, and wearing sunglasses if you're outside for a long period of time
It's my first time hearing about this. There is very limited sources in english on this topic, can you suggest some good one? The one's from the first page of google seems to indicate terminal glasses is a glasses with some sort of magnify \ refracting lenses that allows you to be more than 50cm from a computer with straight posutre. Which is both thing that can be achieved by repositioning yourself & monitor and not letting myopia progress in the first place.
@@jayarmstrong they’re just reading glasses with the correct prescription. What reading glasses do, is they have magnifying lenses, that move your interval of possible focal distances closer to your eyes. A fully sighted person who relaxes their eye muscles will see the horizon in focus, sharply. So that is the fully relaxed state of your eyes. In order to focus closer than the horizon, you need to tighten the ring muscles in your eyes more and more, the closer you look. To focus closer than arms length is quite strenuous, just like Ben said. Reading glasses make you nearsighted, so you are no longer able to focus far away. When you relax your eyes, your focal distance is instead placed much closer. If you measure the distance from your eyes to the edge of your desk, an optician can prescribe you glasses that enable you to focus that far away when your eyes are completely relaxed, but no further. This greatly reduces your eye strain while working at a desk. Your eyes can stay mostly relaxed all day.
What a coincidence. I recently bought a 48" oled tv mostly for playing games and watching movies in a small room. But recently I've started using it as a monitor that's further away so I have also noticed slightly less eye strain relative to the time I've spent at my computer. Thanks for confirming what I've been thinking about!
Look out of the window far into the distance regularly and let your eyes rest as they look at far away objects. Tension of the muscles around the eye cause the reshaping of the lens over time, so massages and relaxing the eye rather than straining can help a lot. Also, literally go outside more.
In a strange way, the lenses and stereoscopy within a VR headset mean this isn’t an issue. You could conceivably use a pair of glasses with a smaller display to put your eyes in their resting focus point, but that wouldn’t fix the convergence point. Potentially good for myopia, but not for eye strain.
I'm curious what you mean. Why a smaller display, or are you just comparing to a monitor? And wouldn't both focal point and the convergence point be affected by how far away the screen/object is in VR?
@@jayarmstrong no, the focal point is always the same in vr, but not the convergence point. that's why everyone is highly "hypertrophic" in VR - you cant focus on near objects at all.
@@jayarmstrong the point is that you can use a smaller display at only 40cm away (so the angular size of the display to you is the same as the large TV) and still have your eyes effectively focusing at 0.8m or beyond.
@@GraveUypo some VR systems have eye-tracking, so in theory they could change the convergence angle on the fly. Any VR system would be able to set the convergence angle at a fixed point, such as the resting point for minimal eye strain. I suspect this is one of the reasons why some VR systems (mainly the Apple Vision Pro) are advertised as being used for workflows of virtual monitors; as an alternative for a conventional screen. Despite the screen being right in front of your face, they’re probably quite a lot better for eye strain and myopia.
My final school project for Design & Technology back in the mid 90s was to build 'the perfect computer desk'. I researched ergonomics and anthropometrics and what I came up with in terms of monitor placement was effectively turning a desk sideways and placing the monitor at one end and the keyboard at the other. Of course they weren't as large monitors back then though.
lol I have been using a 55” LG 4k OLED for years now. The fringing of the text eventually irritated me and I have switched to the 48” which has made a huge difference with text clarity. I still sit at the same distance as the screen is mounted on the wall. I could never imagine going back to a small computer screen again.
@@DawnSentinel Nope. and I have been using an oled since 2022. and I am not super careful with it either. I do put a screen saver but for the most part I treat it like a normal screen. Just a screen saver and task bar that autohides are the only two things I do to avoid burn in. but in all this time (And I use my pc for many many hours on end every single day. I am a 3d animator and vfx artist) so I push this screen to it's limits in terms of hours or continuous use with apps with static UI etc.
Preach, everyone is making fun of me when I tell them I have 48" monitor but actually using big screen seemed to me like the most logical choice - double the screen-space of an ultra-wide monitor plus you can see farther away and it's almost definitely cheaper. The added benefit is that I can use one screen for both work and relax - playing video games, watching movies from a couch etc.
I work with a 28'' monitor, but usually I travel with a 13'' MacBook and I don't understand people who use this as a main the whole time. I notice sight issues when going to the cinema and the only solution is to get a farther (bigger) monitor and looking at something far for a few minutes every while. A pomodoro helps... because while working it's very difficult to remember taking pauses.
To be more specific, looking at anything up close for extended periods of time is thought to be bad. Screens are the modern example, but before that it was the same with books and documents.
@@bawbsmith yes, in Italy we have the example of writer Giacomo Leopaldi (early 1800) with his "studio matto e disperatissimo" (crazy and overly desperate study), he's got sight deficiency and other health issues because of reading and writing for hours with bad lighting.
Thanks for this quick an informative video. I'm a big fan of your setup with the walking desk, your ergonomic keyboard, and last but not least the titular screen. After long time of planning and deliberation, I built my own home office setup with a walking desk, using a treadmill and a height-adjustable table with a 200x80cm top, which has a sturdy monitor arm fastened that can hold two 34" monitors on top of each other. Unfortunately, judging by the eye strain I've had since then, it turns out that those two monitors are too close after all.
hey, mine too! heck even this distance is about the same. but mine's a 48" oled tv. sometimes i watch movies and videos on a projector in my bedroom. i project it on the ceiling and just stay nice and warm under the covers. to be honest, i started this back in 2008 when i tried using my first HDTV as a monitor and just loved it. it was a 32" 1366x768 screen, and the pixels were huge, but i still enjoyed both the size and how relaxed my eyes were when using it so i put up with the low resolution. in 2010 i bought my first 40" tv 1080p screen with the intention of using it as a screen. 2013 i bought another one, 2015 i tried to go back to monitor but i found a 24" screen awful to use, so i sold it and bought a 34" ultrawide which was a nice compromise. then in 2020 i bought my first oled tv, and it was so good that in 2021 i bought this one to use on my pc.
To help myopia, you can also just wear glasses that are +1.0 diopters from your normal far prescription when doing near work. So if you have a -2.0 diopter prescription, you would use -1.0 diopter lenses for near work. If the myopia is being caused by near work, the myopia progression will stop completely.
@@userl-mo4sl The eye focus muscles are able to fully relax when using glasses that do the work for you. Tensed eye focus muscles get stronger and tighter, the same as any other muscle in your body, and in doing so they further progress your myopia. The right glasses allow those focus muscles to rest for the entire time that you are doing close work, letting those muscles loosen up and get smaller over time, which can stop further myopia progression and even offer a small degree of reversal.
Still so little known about myopia in adults. I notice the first source really talked about how myopia progression can continue into adulthood, but doesn't really go into any detail about adult-onset myopia. You notice this everywhere, for example Apple's screen distance feature states that it exists to decrease the chance of myopia in children and to reduce visual stress, they make no claims about myopia for adults. I suppose it's a case of better safe than sorry but if we lived our lives subscribing to every single thing that could possibly maybe reduce some risk (e.g. California telling you tons of things you come into contact with daily can increase your chance of developing cancer), it wouldn't be too fun.
projectors are the main solution with natural reflective light i realised theres is no need to use monitors most times unless its video photo work or movies and games and the other part have to sit in front of a window thats the only place to set up a monitor its not just looking out the window to focus on distance its also the natural light the eyes need at least 2 hours in daytime bright light or else they start to lose focus, they figured it out in south korea and built classrooms with glass roofs
its necessary to focus long distance regularly every 20 minutes thats what the window is for staying in doors naturally causes everyone to look at near objects the eyes worsen the most during development not so much in 20s and older - have a look at "south korea glass classrooms myopia"
Yeah, I too have more than an arm length of distance from screen. More than 80cm but with higher PPI. It always bothered me how most of premade tables doesn't allow to setup screen at such distance without bolting it to a wall & placing keyboard as close to the edge as possible. This is also the reason why I am afraid of trying vr for work \ gaming. Because the screen is so close. Or maybe i'm wrong and it'll actually be a panacea for close work induced myopia. There is a dire need for research on this topic. Though, it seems most of the people who use it constantly already has severe myopia problems. At least from what i personally talked to\ read the articles. Btw the brightness is measured in Lumens, so having 10 of brightness doesn't say much. Also glossy screen are sharper while being prone to reflections, but matte creen are little blurrier while far less dependant on outside lighting conditions. There is also an aspect of outdors having differnt lighting spectrum than blue light of computer screens. It's a complicated subject that can't be boiled down to just low & or hight screen brightness. The dangers of myopia by itself is hugely overstated. I do know a lot of old people who lived through they retirement without any eye operation.
Due to the lense setup, the point where everything is sharp is actually about an arms length away. The lenses make it such that you don't have to foccus right in front of your eyes. In fact, if you pull your virtual hand right up close and foccus it's real blurry. So might actually be helpful!
I got a monitor stand with wheels from amazon and it worked great for me, can move it between rooms and adjust the distance and height as I like. Was pretty affordable too.
I wouldn't say myopia is "eye damage". Unless you have myopia from birth, it's just the eye adapting to what you do. It's a tradeoff, you see better upclose, but worse far away. Using my experience as an example, I used to get very bad headaches when working on the computer for prolonged periods of time until I developed myopia. The damage mostly comes from the myopia being too severe. That increases eye pressure, risk of retinal detachment, risk of macular degeneration, etc...
most curious about the magic keyboard on your platform thing lol in all seriousness I am in the risk range of myopia for vision impairments. even though as far as I understand your eyes stop changing shape after age 20-24, the awareness is super important and would have stopped me from doing many of the things that caused my eyes to progress this far. thank you for making this!
@@BiosElement the magic keyboard is the name of the apple keyboard. i was wondering if there were any use cases for which the voyager does not work. I forgot about the fingerprint sensor lol
It was a shock to see you work in a very similar way to me. I've got a standing desk with a 43 inch 4k so it's not exactly the same, but the treadmill, ergo keyboard, large 4k tv. Cool to know I inadvertently chose a good setup for my eyes.
@AX-fx7ng TV is the KD-43X85K. In the Dolby atmosphere, it's only 60hz but everything is super clear, looks exactly like a PC monitor. I have an underdesk treadmill, the eisenlink one. Just got it as my old one burnt out. The keyboard is my new iteration of the Churri keyboard. Haven't posted it yet as I'm not sure if I want to make some to sell. Mouse is a Logitech lift.
I tried a similar setup with a 48" LG C1 and had mixed feelings about it. In particular my problem was that OLEDs create a bloom effect when you're looking at white text on a dark background. It's an optical illusion I think caused by the extreme contrast that OLEDs are capable of, and it's particularly bad for those with astigmatism like me. I've since gone back to just using my 32" 4k monitor at a regular viewing distance. It can be mitigated by turning down the brightness and contrast, but if it's a setup mostly for office work, I think most people would be better off getting a much cheaper non-OLED tv. Plus you wouldn't have to worry about burn-in.
I've been using a 43" tv as a monitor for years and find myself much less drawn to lean in/slouch toward the screen (which is 4-5 ft away). Definitely recommend, although the framerate limits of cheaper tvs is really frustrating.
save up and buy a c-series LG tv. it's worth it. just don't blast it at 100% brightness all the time and it'll last you a decade. my room is pretty dim and i have a backlight on my screen, i use it at 20% brightness most of the time, except when in HDR (which is obviously full brightness)
The lenses on VR headsets are designed to push your eyes away from the actual screen roughly 1.2m away. So that might be an interesting option. I wonder if in the future they'll push it to dynamically change the lense depending on what you're focusing on, that'd be pretty cool.
The problem is: when you get prescribed glasses, it’s to “fix” your nearsightedness in its totality. If you’re prescribed a pair of glasses -1.00 glasses, that means your eyes can see clearly up to 1 meter. -2.00 means you can see up to 1/2.00 or half a meter. And -4.00 means you can see up to 1/4.00 meter or 25 cm. That means, if your eye doctor tells you you need -2.00 glasses, sure you need them to see everything clearly, BUT not for anything less than 50cm away! Now, to take this even further, even if you have perfect vision and are worried about becoming myopic due to working at the computer for long periods of time, try wearing glasses with a +1.00 power. Positive instead of negative. You will feel less strain in your eyes and will still be able to see up to 1m.
I use an 85 inch tv 1.5m away and aside from tv shows and movies being "too big", both on macos and in games in windows, this is 10x better than my 43 inch monitor with the same relative fiend of view and pixel density at the desk, no noticeablt eyestrain at all
I am using 34'" 4k. 1m without increasing the text size. It's okay for me. With a black theme and if you replace all white with gray, then the eyes do not get tired at all. I dream of a 17 or 10 -inch touch screen for artists 21:9 OLED to always take on the road.
@@Empty_Vima I had a similar realization in this direction; instead of being bright or dark mode both being extremes, why don’t computers use middle ground themes (mid grays , taupes, beige browns coffees) that are not extreme contrast just how most of our external life is - natural earthy shades in middle..
@@AX-fx7ng You have described the themes for the code.(one dark and other) I just don't like white because of its properties and a couple of dependence on brightness. And black doesn't emit light everywhere. There are almost no good reviews about large screens.Even for a 10-inch 21:9 screen, the price will be high relative to the lifespan.
Good video, few corrections are needed though. QD OLED doesn't fic the subpixel arrangement, it has a trinagle pixel arrangement that has somewhat similar artifacts to LG OLEDs, however with their latest monitors the resolution and subpixel shape were improved to somewhat reduce the issue. Further more, LG has a more traditional RGWB pixel arrangement on their latest monitor, making it even better for text than QD OLED. I don't know if they will use the same thing on their upcoming TVs or not.
Theres a reason why i upgraded my screen to a 27" 1440p one and its over a metre away from my face, my eyesight strain has decreased alot over the last year since doing this.
damn watching you write with stenography is motivating me i might start practicing too. seems insanely optimized. especially the latex part was damn beautiful to watch.
@@BenVallack wait that was not stenography? or you mean that it was down computer side? sorry the heat where i live is unbearable (35 c during night time) and i can't focus to figure out what you mean
RPV is an important factor in eyeball lengthening. If you chronically look at close distances, the muscles turning the eyes inward become very tight. Imagine what happens to the eyeball when you then try to look farther away, i.e. the muscles turning the eyeballs outward pull against the tight antagonists.
Did you though of using glasses like XREAL? I am not sure what theirs focal distance is. I would say between 2 and 4 meters. But they are great fit for this I would imagine.
The concept displayed here is not fully correct. It’s the fact that the ability to change in focus of your eyes becomes less powerful and more rigid when we do not do it often.
It looks like there's lots more to it than that after researching this. Your eyeball elongates as a result of the lack of outdoors time and near work. This is a serious issue that makes it harder for your eyes to form a clear image on the retina but also leads to the detached retina issue.
Me at the beginning of this video: leaning on the table, laptop screen finger-span away from my eyes. Me at the end of this video: leaning back in my chair, pushed away from the table, laptop near the wall.
Nice video. I was looking forward to you covering the OLED TV as monitor more in-depth. On a side-note, what is your current video camera set-up that tracks your movement, is it an iPhone?
I have (manageable, but noticeable) myopia and I run a pretty similar setup! And I also use mine for movies. Now, just about the weirdest problem I have with this is I can make it look level when I'm one meter away, but then it looks slightly tilted from across the room when I'm watching TV -- and the other way around! I've measured, leveled, and adjusted everything I could think of so at this point I'm starting to believe it's an optical paradox due to how big it physically is, even if I'm never *that* close to it... Have you ever noticed something like that, or is my apartment just non euclidean?
Good video but you didn't take into consideration many problems that current OLED displays have. For example the PWM flicker issues that most OLED displays have cause eye strain, headaches and other problems. Also OLED displays emit more blue light compared to LCDs affecting your circadian rhythm and interfering with sleep patterns. So OLED displays are not the best for eyes and general health imo. At least not in their current state. Would be nice if you make another video explaining all these issues of OLED and other display technologies.
I don't think OLED tvs use PMW. And blue light is less on OLED than LED. But I think this is more down to what colurs you're actually displaying, i.e you can mitigate it by using a warmer colour temperature. www.rtings.com/tv/reviews/lg/c3-oled
@@BenVallack I’ve seen some generic calculators for for/ distance have that data. Maybe you have better data for it. But after Taking those into account how do they fare in terms of the eyeball stress research? This screen size to height to view distance to eye ball correlation is multi jump correlation - you’ve done it for 55, cam you share some insight for how the 40-50” TVs would do if we were to compare with your 55 in scenario when it comes to eyeball issues.
Wondering if working using Meta Quest 3 or Apple Vision Pro makes sense in terms of myopia and overall eye health. There is definitely positive impact on the back, it’s obvious, but not sure about eye health.
Yeah I'll look into this further but I think they might actually be much better than close screens as they have a fake focus distance well away from your eyes.
Unfortunately, Meta Quest 3's resolution isn't good enough for text, and it requires placing it at just the right position in order to get any level of clarity. While it may solve the "looking too close" problem, you'll end up squinting to read the jaggy text and constantly readjusting your headset whenever you move your head. I hear Vision Pro is slightly better, but still not good enough for text-based work. I haven't gotten the chance to try it myself, but based on discussions on reddit and other message boards this seems to be the case.
@@BenVallackthat’s what I was wondering. If the pseudo distance actually works and how it affects the eyeball. Do reply to 40-50” TV comment query I made. Gracias.
@@BenVallack Varifocal should solve this in the future. I’m using Meta Quest 3 currently and even for coding sometimes. I’d say I have less eye strain using Quest 3 than regular monitor. Though I use open facial interface to avoid dry eye. Anyways I’m looking forward for the future where monitor adapts to your position, not otherwise.
Yes, just tried the Viture Pro. FHD and simulated about a meter away. I believe you can place the virtual display further out with their app. Great for less productive use. Great in a lot of ways actually.
@@jayarmstrong I haven’t heard of that model before, but it looks nice (though I suppose it doesn’t have head tracking?). Also, what about eye strain? I’ve heard some people experience eye strain when using the NReal Airs for too long, which is obviously less than ideal when you’re buying them specifically to combat it.
It would be awesome to hear your opinion about AR glasses for programming (or generic CS work). I can't stop imagining being able to put on smart glasses and a small splitted keyboard (like a Splinky or something) for train/plane/metro/bus traveling, while keeping the laptop in the backpack and just connect to it with the glasses! I think that I am going to try this sooner or later.
Yeah I forgot to put a subtitle up - it's only visible from where the camera is. The angle where I am is good - I have a black fabric wall behind me concealing sound treatment so that knocks the reflections right out.
Do you know of endmyopia? Reversing myopia by slowly decreasing the diopters in your prescription by 0.25 until you get back to 20/20? Has that improved your eyesight at all?
@@EconaelGaming i was like -4.00, i think i should be at like -3.50 now. The differential glasses that are only powerful enough to see the computer screen also helped me with eye strain
The method works to reduce myopia, though creating enough stimuli to reverse back to 20/20 might be borderline impossible depending on your lifestyle. Also I don't trust the guy behind the "endmyopia" brand. I recommend watching the videos uploaded by the channel "cliffgnu" to learn more.
Isn't the siting close to the screen thing a myth? it just might be uncomfortable and cause eye strain if you're TOO close I'll watch the video tho! but I heard 25cm is good to avoid it and taking breaks is more important?
what do you think of the way Apple Vision Pro displays images to your eyes? does the light coming into your eyes technically make your eyes focus at a distance or at a very close range? 💭
Now that i'm in my 40s i have the opposite problem, farsightedness x.x Other than adjusting my prescription, which i already have, not sure what to do about that :D
Too bad I am shortsighted due to genetics with my dad being like -10 lol, would be nice to have properly shaped eyes. BTW even 2nd-gen QD oled doesn't fix the text issue, the only fix is a true RGB-stripe display (which QD oleds are not, they are a somewhat triangular layout). Every oled display has major compromises like that, smartphones have the awful pentile layout which is even worse than WOLED or first gen QD lol
If you're using a normal screen, I wonder how much you can counteract risks to health by occasionally resting your eyes by closing them (as I am doing touch typing this) or by looking off into the distance occasionally.
That is supposed to help a lot. Also hours outside... Particularly because of the brightness, though I suspect it's also because of infrared and the rest of the natural spectrum.
"There are some alarming health risks associated with using just a normal fan instead of a purifying fan, and I go into that in this video" - Where? What video? There's no link anywhere.
All your points seem valid. but what about reflections on the glossy screen? I tried a 48'' c2 and had to darken my back wall with blankets and close the blinds to reduce eye strain from reflections (reflections at 4:15 look bad). currently running 2x Dell u2724de (1 vertical) at a bit more than arms length and am happier with the setup. Auto brightness is a huge plus and the anti glare coating is quite good. ips black, 1440p to run at 100% scaling, 120hz and built in kvm is just perfect. 6500k bias lighting also does wonders IMHO.
I have experienced significantly less eye strain over the past four months with my AVP. Unfortunately, Apple insists on making everything from metal and glass, which has led to some discomfort manifesting as neck and face strain. Oh well, I guess you can't have everything right away.
massive - 1.2m is comfortably past the resting point of accommodation and the resting point of vergence. 0.2m is less than 12" and 12" requires 2.5x more effort to focus on than 30".
makes sense. i’ve got maybe a meter between my screen and myself but it’s not as legible with much smaller fonts etc. was thinking of doing your setup for some time now, just didn’t know if it’s worth it. i’d rather take walks and train the eye on longer distances at various points throughout the day to recompense if that makes sense
one point six meters is not far at all, but i work off the kings inch... i sit over seven feet, a bit over two meters, and thats because i cant move back i would like about another foot, maybe two but dont have the space they used to tell us to sit ten feet away from 56" stuff like this is a no brainer, but these days people cant seem to tell their ass from a hole in the ground unless a talking head explains how to poke around and find out so i guess good on this channel for doing a public service in an age bereft of personal accountability
@@BankruptGreek It's more about eco system integration. I'm locked in to the apple world so I need the reliable device switching which just isn't there with regular bluetooth. Noise cancelling is also class leading. The fold-flat design is also excellent. They sound great too. It's mostly the seem less integration with apple products though - they get passed around the family quite a lot and the seamless connection stuff is very good. Also visual design/hardware quality is next level compared to the plastic crap that competes with them. Also before it started sagging the headband was exceptionally good. Unfortunately that only lasted about a year so I have the silicone insert in there now. Which granted does somewhat detract from the aesthetics!!

I think the optics used here might actually make it be further away than it looks, similarly to looking through a pair of binoculars, though I'm unsure if the effect there is big enough to make a large difference, someone else might know better in this area and can fill me in here.
@@swecreationsthe lenses in VR take an image that is inches from your eye and project it to about 1.5-2 metres away, so it will be better than a close screen, the only problem is everything is in that same focal plane, no matter how near or far it is in VR, so your eye spends a lot of time focusing at a very fixed distance. I use VR as a monitor replacement most days, so it is comfortable, but i am cautious on long term eye health
I dont think the scientific evidence is nearly as conclusive as you present in this video. In particular whether or not corrected myopia will worsen due to ongoing near work as an adult.
When there's at least some evidence it makes sense to not take the risk I'd say! Even if there's no risk of progression we still have the issue of eye strain and comfort. Once you get out to the RPV it's so much more comfortable. In any case, the myopia risks associated with near work seem very conclusive for people under 20 so we should spread that message far and wide!
It's more than hypothetical; there's a growing mountain of evidence from longitudinal studies that show children who spend more time outdoors and less time doing near work are far more likely not to have myopia, even when adjusting for external factors. One thing we can say for sure is that it's *not only* genetic factors. If that were the case, there's no explanation as to why there's been an abrupt and sharp increase in people with myopia in the past few decades.
can you talk more about the setup instead of doing a deep dive into the myopia stuff, you're not a doctor, it took up way too much of the video and my interest, the video is only sectioned into "study talk and your eyes" and OLED TV discussion..
This vid was about why I went for the big screen and that was entirely based on the eye strain and eye health concerns. This vid is more about the setup itself: ruclips.net/video/a__6yuHWVMA/видео.html

Less time spent outside *as a child*. It is important to get enough sunlight when you are a child and are growing.

@@jayarmstrong the epidemic of myopia that develops in children is because as they are growing, they don't receive enough sunlight (2 hours a days of direct sunlight every day). Because of that, the eyeball keeps lengthening.
After the person has stopped growing, the amount of sunlight you receive does not affect the growth of the eye anymore.
This is also the reason the eyesight settles towards the end of the teen years and they recommend to do LASIK surgery after your eyesight has settles.
I've heard you can also reverse myopia when you're an adult if you pay attention to how much time you spend looking at things up close versus far away, and getting enough sunlight, so it's not just a hopeless case for adults.
@@utubekullanicisi as far as I am aware, you can only reduce the risk of developing myopia by getting enough sunlight. It is most important to get sunlight during your developing years, but some have said to also get enough sunlight in your twenties, I am not 100% certain on the reason why so I won't mention it. But I haven't found any study or article mentioning reversing myopia.
@@utubekullanicisiIt's a myth desperate people like to believe in
In Sweden, if you work more than 1 hour per day in front of a screen, your employer must pay for eye exams and "terminal glasses" - basically individually adapted reading glasses so your eyes can relax. You intentionally make yourself nearsighted enough that the horizon focal distance moves to the edge of your desk.
I wish you would have mentioned reading glasses as a good option for those who do not have the money or space to work in front of a huge TV. 😊
This is very interesting indeed.
Would love to understand this. So these terminal glasses make your eyes work harder to see distant objects? What exactly moves to which edge of the desk?
@@jayarmstrong I recon they block blue light and glare commonly associated with eye strain. if you have glasses consider getting a pair with glare/blue light reduction, and wearing sunglasses if you're outside for a long period of time
It's my first time hearing about this. There is very limited sources in english on this topic, can you suggest some good one? The one's from the first page of google seems to indicate terminal glasses is a glasses with some sort of magnify \ refracting lenses that allows you to be more than 50cm from a computer with straight posutre. Which is both thing that can be achieved by repositioning yourself & monitor and not letting myopia progress in the first place.
@@jayarmstrong they’re just reading glasses with the correct prescription. What reading glasses do, is they have magnifying lenses, that move your interval of possible focal distances closer to your eyes.
A fully sighted person who relaxes their eye muscles will see the horizon in focus, sharply. So that is the fully relaxed state of your eyes. In order to focus closer than the horizon, you need to tighten the ring muscles in your eyes more and more, the closer you look. To focus closer than arms length is quite strenuous, just like Ben said. Reading glasses make you nearsighted, so you are no longer able to focus far away. When you relax your eyes, your focal distance is instead placed much closer.
If you measure the distance from your eyes to the edge of your desk, an optician can prescribe you glasses that enable you to focus that far away when your eyes are completely relaxed, but no further. This greatly reduces your eye strain while working at a desk. Your eyes can stay mostly relaxed all day.
What a coincidence. I recently bought a 48" oled tv mostly for playing games and watching movies in a small room. But recently I've started using it as a monitor that's further away so I have also noticed slightly less eye strain relative to the time I've spent at my computer. Thanks for confirming what I've been thinking about!
Look out of the window far into the distance regularly and let your eyes rest as they look at far away objects. Tension of the muscles around the eye cause the reshaping of the lens over time, so massages and relaxing the eye rather than straining can help a lot. Also, literally go outside more.
Great video. A couple of years ago I set up my screen 70cm away, so I was relieved to see that this was the smallest distance to not be too close
In a strange way, the lenses and stereoscopy within a VR headset mean this isn’t an issue. You could conceivably use a pair of glasses with a smaller display to put your eyes in their resting focus point, but that wouldn’t fix the convergence point. Potentially good for myopia, but not for eye strain.
I'm curious what you mean. Why a smaller display, or are you just comparing to a monitor? And wouldn't both focal point and the convergence point be affected by how far away the screen/object is in VR?
@@jayarmstrong no, the focal point is always the same in vr, but not the convergence point. that's why everyone is highly "hypertrophic" in VR - you cant focus on near objects at all.
@@jayarmstrong the point is that you can use a smaller display at only 40cm away (so the angular size of the display to you is the same as the large TV) and still have your eyes effectively focusing at 0.8m or beyond.
@@GraveUypo some VR systems have eye-tracking, so in theory they could change the convergence angle on the fly. Any VR system would be able to set the convergence angle at a fixed point, such as the resting point for minimal eye strain. I suspect this is one of the reasons why some VR systems (mainly the Apple Vision Pro) are advertised as being used for workflows of virtual monitors; as an alternative for a conventional screen. Despite the screen being right in front of your face, they’re probably quite a lot better for eye strain and myopia.
Ar glasses like xreal air
My final school project for Design & Technology back in the mid 90s was to build 'the perfect computer desk'. I researched ergonomics and anthropometrics and what I came up with in terms of monitor placement was effectively turning a desk sideways and placing the monitor at one end and the keyboard at the other. Of course they weren't as large monitors back then though.
Unfortunately most modern office desks have T-shaped legs at the sides, which makes this usage of the desk impossible.
@@EconaelGaming sorry if I wasn't clear. For my school project I welded my own leg structure for the desk.
lol I have been using a 55” LG 4k OLED for years now. The fringing of the text eventually irritated me and I have switched to the 48” which has made a huge difference with text clarity. I still sit at the same distance as the screen is mounted on the wall. I could never imagine going back to a small computer screen again.
Have you had any burn in problems? That tends to be an issue with using oleds for productivity work.
@@DawnSentinel Nope. and I have been using an oled since 2022. and I am not super careful with it either. I do put a screen saver but for the most part I treat it like a normal screen. Just a screen saver and task bar that autohides are the only two things I do to avoid burn in. but in all this time (And I use my pc for many many hours on end every single day. I am a 3d animator and vfx artist) so I push this screen to it's limits in terms of hours or continuous use with apps with static UI etc.
Preach, everyone is making fun of me when I tell them I have 48" monitor but actually using big screen seemed to me like the most logical choice - double the screen-space of an ultra-wide monitor plus you can see farther away and it's almost definitely cheaper. The added benefit is that I can use one screen for both work and relax - playing video games, watching movies from a couch etc.
I also use a 55” and I’m sat about 160cm away. I’d go larger and sit further but my office size is limiting.
So, slouching over my old 11" macbook Air on a random train is not the ultimate way of doing things?
I work with a 28'' monitor, but usually I travel with a 13'' MacBook and I don't understand people who use this as a main the whole time. I notice sight issues when going to the cinema and the only solution is to get a farther (bigger) monitor and looking at something far for a few minutes every while. A pomodoro helps... because while working it's very difficult to remember taking pauses.
damn, so looking at screens up close was really bad
To be more specific, looking at anything up close for extended periods of time is thought to be bad.
Screens are the modern example, but before that it was the same with books and documents.
@@bawbsmith yes, in Italy we have the example of writer Giacomo Leopaldi (early 1800) with his "studio matto e disperatissimo" (crazy and overly desperate study), he's got sight deficiency and other health issues because of reading and writing for hours with bad lighting.
I mean there's a reason the sterotype for a nerd includes glasses 🤓. Too many books
Thanks for this quick an informative video.
I'm a big fan of your setup with the walking desk, your ergonomic keyboard, and last but not least the titular screen.
After long time of planning and deliberation, I built my own home office setup with a walking desk, using a treadmill and a height-adjustable table with a 200x80cm top, which has a sturdy monitor arm fastened that can hold two 34" monitors on top of each other.
Unfortunately, judging by the eye strain I've had since then, it turns out that those two monitors are too close after all.
great video, thanks for pointing this out! will think about this next time I'll change my setup.
hey, mine too! heck even this distance is about the same. but mine's a 48" oled tv.
sometimes i watch movies and videos on a projector in my bedroom. i project it on the ceiling and just stay nice and warm under the covers.
to be honest, i started this back in 2008 when i tried using my first HDTV as a monitor and just loved it. it was a 32" 1366x768 screen, and the pixels were huge, but i still enjoyed both the size and how relaxed my eyes were when using it so i put up with the low resolution. in 2010 i bought my first 40" tv 1080p screen with the intention of using it as a screen. 2013 i bought another one, 2015 i tried to go back to monitor but i found a 24" screen awful to use, so i sold it and bought a 34" ultrawide which was a nice compromise. then in 2020 i bought my first oled tv, and it was so good that in 2021 i bought this one to use on my pc.
To help myopia, you can also just wear glasses that are +1.0 diopters from your normal far prescription when doing near work. So if you have a -2.0 diopter prescription, you would use -1.0 diopter lenses for near work. If the myopia is being caused by near work, the myopia progression will stop completely.
Why is the reason for that?
@@userl-mo4sl The eye focus muscles are able to fully relax when using glasses that do the work for you. Tensed eye focus muscles get stronger and tighter, the same as any other muscle in your body, and in doing so they further progress your myopia. The right glasses allow those focus muscles to rest for the entire time that you are doing close work, letting those muscles loosen up and get smaller over time, which can stop further myopia progression and even offer a small degree of reversal.
I got a 55" Samsung S90C and have been using it as my main monitor, I also do dev work, and it has worked amazing for my use case.
Still so little known about myopia in adults. I notice the first source really talked about how myopia progression can continue into adulthood, but doesn't really go into any detail about adult-onset myopia. You notice this everywhere, for example Apple's screen distance feature states that it exists to decrease the chance of myopia in children and to reduce visual stress, they make no claims about myopia for adults. I suppose it's a case of better safe than sorry but if we lived our lives subscribing to every single thing that could possibly maybe reduce some risk (e.g. California telling you tons of things you come into contact with daily can increase your chance of developing cancer), it wouldn't be too fun.
projectors are the main solution with natural reflective light i realised theres is no need to use monitors most times unless its video photo work or movies and games and the other part have to sit in front of a window thats the only place to set up a monitor its not just looking out the window to focus on distance its also the natural light the eyes need at least 2 hours in daytime bright light or else they start to lose focus, they figured it out in south korea and built classrooms with glass roofs
its necessary to focus long distance regularly every 20 minutes thats what the window is for staying in doors naturally causes everyone to look at near objects the eyes worsen the most during development not so much in 20s and older - have a look at "south korea glass classrooms myopia"
Which projector are you using for office work?
Yeah, I too have more than an arm length of distance from screen. More than 80cm but with higher PPI. It always bothered me how most of premade tables doesn't allow to setup screen at such distance without bolting it to a wall & placing keyboard as close to the edge as possible.
This is also the reason why I am afraid of trying vr for work \ gaming. Because the screen is so close. Or maybe i'm wrong and it'll actually be a panacea for close work induced myopia. There is a dire need for research on this topic.
Though, it seems most of the people who use it constantly already has severe myopia problems.
At least from what i personally talked to\ read the articles.
Btw the brightness is measured in Lumens, so having 10 of brightness doesn't say much. Also glossy screen are sharper while being prone to reflections, but matte creen are little blurrier while far less dependant on outside lighting conditions. There is also an aspect of outdors having differnt lighting spectrum than blue light of computer screens. It's a complicated subject that can't be boiled down to just low & or hight screen brightness.
The dangers of myopia by itself is hugely overstated. I do know a lot of old people who lived through they retirement without any eye operation.
Due to the lense setup, the point where everything is sharp is actually about an arms length away. The lenses make it such that you don't have to foccus right in front of your eyes. In fact, if you pull your virtual hand right up close and foccus it's real blurry. So might actually be helpful!
I got a monitor stand with wheels from amazon and it worked great for me, can move it between rooms and adjust the distance and height as I like. Was pretty affordable too.
I wouldn't say myopia is "eye damage". Unless you have myopia from birth, it's just the eye adapting to what you do. It's a tradeoff, you see better upclose, but worse far away. Using my experience as an example, I used to get very bad headaches when working on the computer for prolonged periods of time until I developed myopia. The damage mostly comes from the myopia being too severe. That increases eye pressure, risk of retinal detachment, risk of macular degeneration, etc...
Is this the same when using a VR headset? The panals themselves are insanely close but you focus on them as though you're looking at a distant object.
Yeah I believe so - I'm not quite sure how they deal with convergence though.
@@BenVallacki guess, the lens system is designed so, that it makes your eyes work as if you look at distant objects.
most curious about the magic keyboard on your platform thing lol
in all seriousness I am in the risk range of myopia for vision impairments. even though as far as I understand your eyes stop changing shape after age 20-24, the awareness is super important and would have stopped me from doing many of the things that caused my eyes to progress this far. thank you for making this!
ZSA Voyager, I have that and the Moonlander and both are super solid.
@@BiosElement the magic keyboard is the name of the apple keyboard. i was wondering if there were any use cases for which the voyager does not work. I forgot about the fingerprint sensor lol
It was a shock to see you work in a very similar way to me. I've got a standing desk with a 43 inch 4k so it's not exactly the same, but the treadmill, ergo keyboard, large 4k tv. Cool to know I inadvertently chose a good setup for my eyes.
@@supernifty which TV, panel type and so on; do share your details.
@AX-fx7ng TV is the KD-43X85K. In the Dolby atmosphere, it's only 60hz but everything is super clear, looks exactly like a PC monitor. I have an underdesk treadmill, the eisenlink one. Just got it as my old one burnt out. The keyboard is my new iteration of the Churri keyboard. Haven't posted it yet as I'm not sure if I want to make some to sell. Mouse is a Logitech lift.
I just ordered a 43 inch 4K QLED and I'm wondering if it will be large enough for this. Sounds like it works for you
I tried a similar setup with a 48" LG C1 and had mixed feelings about it. In particular my problem was that OLEDs create a bloom effect when you're looking at white text on a dark background. It's an optical illusion I think caused by the extreme contrast that OLEDs are capable of, and it's particularly bad for those with astigmatism like me. I've since gone back to just using my 32" 4k monitor at a regular viewing distance.
It can be mitigated by turning down the brightness and contrast, but if it's a setup mostly for office work, I think most people would be better off getting a much cheaper non-OLED tv. Plus you wouldn't have to worry about burn-in.
I've been using a 43" tv as a monitor for years and find myself much less drawn to lean in/slouch toward the screen (which is 4-5 ft away).
Definitely recommend, although the framerate limits of cheaper tvs is really frustrating.
save up and buy a c-series LG tv. it's worth it. just don't blast it at 100% brightness all the time and it'll last you a decade. my room is pretty dim and i have a backlight on my screen, i use it at 20% brightness most of the time, except when in HDR (which is obviously full brightness)
The lenses on VR headsets are designed to push your eyes away from the actual screen roughly 1.2m away.
So that might be an interesting option.
I wonder if in the future they'll push it to dynamically change the lense depending on what you're focusing on, that'd be pretty cool.
The problem is: when you get prescribed glasses, it’s to “fix” your nearsightedness in its totality. If you’re prescribed a pair of glasses -1.00 glasses, that means your eyes can see clearly up to 1 meter. -2.00 means you can see up to 1/2.00 or half a meter. And -4.00 means you can see up to 1/4.00 meter or 25 cm. That means, if your eye doctor tells you you need -2.00 glasses, sure you need them to see everything clearly, BUT not for anything less than 50cm away! Now, to take this even further, even if you have perfect vision and are worried about becoming myopic due to working at the computer for long periods of time, try wearing glasses with a +1.00 power. Positive instead of negative. You will feel less strain in your eyes and will still be able to see up to 1m.
I use an 85 inch tv 1.5m away and aside from tv shows and movies being "too big", both on macos and in games in windows, this is 10x better than my 43 inch monitor with the same relative fiend of view and pixel density at the desk, no noticeablt eyestrain at all
I am using 34'" 4k. 1m without increasing the text size. It's okay for me. With a black theme and if you replace all white with gray, then the eyes do not get tired at all. I dream of a 17 or 10 -inch touch screen for artists 21:9 OLED to always take on the road.
Nice!
@@Empty_Vima I had a similar realization in this direction; instead of being bright or dark mode both being extremes, why don’t computers use middle ground themes (mid grays , taupes, beige browns coffees) that are not extreme contrast just how most of our external life is - natural earthy shades in middle..
@@AX-fx7ng You have described the themes for the code.(one dark and other) I just don't like white because of its properties and a couple of dependence on brightness. And black doesn't emit light everywhere.
There are almost no good reviews about large screens.Even for a 10-inch 21:9 screen, the price will be high relative to the lifespan.
Good video, few corrections are needed though. QD OLED doesn't fic the subpixel arrangement, it has a trinagle pixel arrangement that has somewhat similar artifacts to LG OLEDs, however with their latest monitors the resolution and subpixel shape were improved to somewhat reduce the issue.
Further more, LG has a more traditional RGWB pixel arrangement on their latest monitor, making it even better for text than QD OLED. I don't know if they will use the same thing on their upcoming TVs or not.
Great info cheers
Love the keyboard set up
Will be looking at that in the next few weeks as part of a closer look at the treadmill setup
Might make sense to get a projector. Though, in my experience they're pretty loud.
They also generally reside a dimmer environment
Theres a reason why i upgraded my screen to a 27" 1440p one and its over a metre away from my face, my eyesight strain has decreased alot over the last year since doing this.
Hmpf, my nearsightedness is so bad already that a 27" screen looks pretty small when I wear my glasses 🙈
I use an eink monitor for this reason
damn watching you write with stenography is motivating me
i might start practicing too. seems insanely optimized. especially the latex part was damn beautiful to watch.
It's actually a regular keyboard - not qwerty but still just normal keys.
@@BenVallack wait that was not stenography? or you mean that it was down computer side? sorry the heat where i live is unbearable (35 c during night time) and i can't focus to figure out what you mean
Hey, I love your productivity videos, especially the ones for split keyboards.
Could you make a video about your mac os productivity setup?
RPV is an important factor in eyeball lengthening. If you chronically look at close distances, the muscles turning the eyes inward become very tight. Imagine what happens to the eyeball when you then try to look farther away, i.e. the muscles turning the eyeballs outward pull against the tight antagonists.
Did you though of using glasses like XREAL? I am not sure what theirs focal distance is. I would say between 2 and 4 meters. But they are great fit for this I would imagine.
The concept displayed here is not fully correct. It’s the fact that the ability to change in focus of your eyes becomes less powerful and more rigid when we do not do it often.
It looks like there's lots more to it than that after researching this. Your eyeball elongates as a result of the lack of outdoors time and near work. This is a serious issue that makes it harder for your eyes to form a clear image on the retina but also leads to the detached retina issue.
great vid as always, go into the world of longevity please, theres some cool stuff like broccoli sprouts that could be very interesting
Me at the beginning of this video: leaning on the table, laptop screen finger-span away from my eyes.
Me at the end of this video: leaning back in my chair, pushed away from the table, laptop near the wall.
Nice video. I was looking forward to you covering the OLED TV as monitor more in-depth. On a side-note, what is your current video camera set-up that tracks your movement, is it an iPhone?
Ronin SC with active track and Sony ZV-E1. I didn't have you thinking I have someone filming me then heh!
I have (manageable, but noticeable) myopia and I run a pretty similar setup! And I also use mine for movies.
Now, just about the weirdest problem I have with this is I can make it look level when I'm one meter away, but then it looks slightly tilted from across the room when I'm watching TV -- and the other way around!
I've measured, leveled, and adjusted everything I could think of so at this point I'm starting to believe it's an optical paradox due to how big it physically is, even if I'm never *that* close to it...
Have you ever noticed something like that, or is my apartment just non euclidean?
It's funny you say that I did experience exactly that! I don't notice any more but I do recall thinking that!
Good video but you didn't take into consideration many problems that current OLED displays have.
For example the PWM flicker issues that most OLED displays have cause eye strain, headaches and other problems.
Also OLED displays emit more blue light compared to LCDs affecting your circadian rhythm and interfering with sleep patterns.
So OLED displays are not the best for eyes and general health imo. At least not in their current state.
Would be nice if you make another video explaining all these issues of OLED and other display technologies.
I don't think OLED tvs use PMW. And blue light is less on OLED than LED. But I think this is more down to what colurs you're actually displaying, i.e you can mitigate it by using a warmer colour temperature. www.rtings.com/tv/reviews/lg/c3-oled
Isn't reading books are equally bad from this perspective, not just phones tablets?
Absolutely!
Yes, but it's hard to read books for 8+ hours a day straight.
Yes. Looks like this myopia problem correlates with school classrooms, textbooks, staying indoors, artificial light, screens, and near work.
Do share some of your numbers and math on 42/43 AND 48/50” Screens and IPS for those who already use non OLED TVs of these 43-50 in sizes.
Do you mean you'd like to know how far away those size screens would be away from you at equivalent field of view to my setup?
@@BenVallack I’ve seen some generic calculators for for/ distance have that data. Maybe you have better data for it. But after Taking those into account how do they fare in terms of the eyeball stress research? This screen size to height to view distance to eye ball correlation is multi jump correlation - you’ve done it for 55, cam you share some insight for how the 40-50” TVs would do if we were to compare with your 55 in scenario when it comes to eyeball issues.
Nice vid mate
Why is this person so much like my better twin?
Wondering if working using Meta Quest 3 or Apple Vision Pro makes sense in terms of myopia and overall eye health. There is definitely positive impact on the back, it’s obvious, but not sure about eye health.
Yeah I'll look into this further but I think they might actually be much better than close screens as they have a fake focus distance well away from your eyes.
Unfortunately, Meta Quest 3's resolution isn't good enough for text, and it requires placing it at just the right position in order to get any level of clarity.
While it may solve the "looking too close" problem, you'll end up squinting to read the jaggy text and constantly readjusting your headset whenever you move your head.
I hear Vision Pro is slightly better, but still not good enough for text-based work. I haven't gotten the chance to try it myself, but based on discussions on reddit and other message boards this seems to be the case.
@@BenVallackthat’s what I was wondering. If the pseudo distance actually works and how it affects the eyeball. Do reply to 40-50” TV comment query I made. Gracias.
@@BenVallack Varifocal should solve this in the future. I’m using Meta Quest 3 currently and even for coding sometimes. I’d say I have less eye strain using Quest 3 than regular monitor. Though I use open facial interface to avoid dry eye.
Anyways I’m looking forward for the future where monitor adapts to your position, not otherwise.
@@bawbsmith Very interesting cheers
Good Thanks
I'm far sighted, I guess I should move my monitor closer and go out less :D
I’ve actually considered buying an nreal air particularly to prevent eye strain for a while now. Anybody here tried something similar?
Yeah I think they could work pretty well but they're only HD so text is going to look pretty low res. I'd love try a set though.
Yes, just tried the Viture Pro. FHD and simulated about a meter away. I believe you can place the virtual display further out with their app. Great for less productive use. Great in a lot of ways actually.
@@jayarmstrong I haven’t heard of that model before, but it looks nice (though I suppose it doesn’t have head tracking?).
Also, what about eye strain? I’ve heard some people experience eye strain when using the NReal Airs for too long, which is obviously less than ideal when you’re buying them specifically to combat it.
Im in fear now as a software development student
It would be awesome to hear your opinion about AR glasses for programming (or generic CS work). I can't stop imagining being able to put on smart glasses and a small splitted keyboard (like a Splinky or something) for train/plane/metro/bus traveling, while keeping the laptop in the backpack and just connect to it with the glasses! I think that I am going to try this sooner or later.
Yeah keen to try something soon
But my monitor is newwww, why do you do this to me! Excellent information as always Ben!
The distance seems fine but in some of the shots the glare just looks unbearable, that can't be good. It might just be from the camera's angle.
Yeah I forgot to put a subtitle up - it's only visible from where the camera is. The angle where I am is good - I have a black fabric wall behind me concealing sound treatment so that knocks the reflections right out.
Do you know of endmyopia? Reversing myopia by slowly decreasing the diopters in your prescription by 0.25 until you get back to 20/20?
Has that improved your eyesight at all?
I've gone from -2.75 down to -1.0, it works.
@@EconaelGaming i was like -4.00, i think i should be at like -3.50 now. The differential glasses that are only powerful enough to see the computer screen also helped me with eye strain
The method works to reduce myopia, though creating enough stimuli to reverse back to 20/20 might be borderline impossible depending on your lifestyle. Also I don't trust the guy behind the "endmyopia" brand. I recommend watching the videos uploaded by the channel "cliffgnu" to learn more.
@@agaga5886 I used cliffgnu's guide. Hadn't heard of "endmyopia".
@@agaga5886 i've seen some of his posts as well, thanks for the reminder
The color fringing is probably due to 4:2:2 color encoding rather than the white subpixel
No, the color fringing is a physical property of a display due to the RWBG pixel patter
@@szlomobronsztajn3115 I'd be interested in reading more researched information about this. Got any data to share ?
Isn't the siting close to the screen thing a myth?
it just might be uncomfortable and cause eye strain if you're TOO close
I'll watch the video tho! but I heard 25cm is good to avoid it and taking breaks is more important?
looks good but your screen is too low. You should put it higher so you dont look down all the time
Top of the screen is level with my eyes so it's bang on. I know it looks lower in some of the shots
what do you think of the way Apple Vision Pro displays images to your eyes? does the light coming into your eyes technically make your eyes focus at a distance or at a very close range? 💭
Yeah it will simulate a further focus distance as far as I'm aware. Not quite sure how it deals with the convergence though.
The only draw back i see in the treadmill setup is that i wont benefit from spacetime dilation when actually walking
You sir are on a higher plane!
Now that i'm in my 40s i have the opposite problem, farsightedness x.x Other than adjusting my prescription, which i already have, not sure what to do about that :D
New fear unlocked
6:20 Or a curved screen!
Isnˋt a beamer as a screen the logical next step then?
Too bad I am shortsighted due to genetics with my dad being like -10 lol, would be nice to have properly shaped eyes. BTW even 2nd-gen QD oled doesn't fix the text issue, the only fix is a true RGB-stripe display (which QD oleds are not, they are a somewhat triangular layout). Every oled display has major compromises like that, smartphones have the awful pentile layout which is even worse than WOLED or first gen QD lol
Very interesting thanks!
Have you tried projectors?
Not getting into VR anytime soon then 😅
If you're using a normal screen, I wonder how much you can counteract risks to health by occasionally resting your eyes by closing them (as I am doing touch typing this) or by looking off into the distance occasionally.
That is supposed to help a lot. Also hours outside... Particularly because of the brightness, though I suspect it's also because of infrared and the rest of the natural spectrum.
tfw you sit 1.2m away but with 24" monitors
eek - scaled UI?
"There are some alarming health risks associated with using just a normal fan instead of a purifying fan, and I go into that in this video" - Where? What video? There's no link anywhere.
There should be a popup link on screen at the end - it's this one though. ruclips.net/video/HmgExMX0VeY/видео.html
All your points seem valid. but what about reflections on the glossy screen? I tried a 48'' c2 and had to darken my back wall with blankets and close the blinds to reduce eye strain from reflections (reflections at 4:15 look bad). currently running 2x Dell u2724de (1 vertical) at a bit more than arms length and am happier with the setup. Auto brightness is a huge plus and the anti glare coating is quite good. ips black, 1440p to run at 100% scaling, 120hz and built in kvm is just perfect. 6500k bias lighting also does wonders IMHO.
Your screen is too low, your lighting is too dark.your walk and type had me laugh, thank you
I wonder if simulated distance works - like with the apple vision pro
Yeah I'd like to dig deeper into that - if your eye thinks it's focusing far away my hunch is that it would be the same effect.
I have experienced significantly less eye strain over the past four months with my AVP. Unfortunately, Apple insists on making everything from metal and glass, which has led to some discomfort manifesting as neck and face strain. Oh well, I guess you can't have everything right away.
@@lugovov I'm REALLY excited for the immersed visor. Similar screen quality, much lighter. Purpose made for productivity.

how much of a difference is 0.2m vs 1.2m ?
massive - 1.2m is comfortably past the resting point of accommodation and the resting point of vergence. 0.2m is less than 12" and 12" requires 2.5x more effort to focus on than 30".
makes sense. i’ve got maybe a meter between my screen and myself but it’s not as legible with much smaller fonts etc. was thinking of doing your setup for some time now, just didn’t know if it’s worth it. i’d rather take walks and train the eye on longer distances at various points throughout the day to recompense if that makes sense
one point six meters is not far at all, but i work off the kings inch...
i sit over seven feet, a bit over two meters, and thats because i cant move back
i would like about another foot, maybe two but dont have the space
they used to tell us to sit ten feet away from 56"
stuff like this is a no brainer, but these days people cant seem to tell their ass from a hole in the ground unless a talking head explains how to poke around and find out
so i guess good on this channel for doing a public service in an age bereft of personal accountability

Worried about radiation?
@@BenVallackno, just that there are way better options out there. To me it screams design/appearance is more important to you than function
@@BankruptGreek It's more about eco system integration. I'm locked in to the apple world so I need the reliable device switching which just isn't there with regular bluetooth. Noise cancelling is also class leading. The fold-flat design is also excellent. They sound great too. It's mostly the seem less integration with apple products though - they get passed around the family quite a lot and the seamless connection stuff is very good. Also visual design/hardware quality is next level compared to the plastic crap that competes with them. Also before it started sagging the headband was exceptionally good. Unfortunately that only lasted about a year so I have the silicone insert in there now. Which granted does somewhat detract from the aesthetics!!
It was pretty disappointing seeing you using overprices super low efficient dieson purifying fan, dyson fan don't have most of air filtered at all and just go thru hole in fan
Much more to them than meets the eye: ruclips.net/video/HmgExMX0VeY/видео.html
Meanwhile. Apple. "Here's a screen for your entire face"
I think the optics used here might actually make it be further away than it looks, similarly to looking through a pair of binoculars, though I'm unsure if the effect there is big enough to make a large difference, someone else might know better in this area and can fill me in here.
@@swecreationsthe lenses in VR take an image that is inches from your eye and project it to about 1.5-2 metres away, so it will be better than a close screen, the only problem is everything is in that same focal plane, no matter how near or far it is in VR, so your eye spends a lot of time focusing at a very fixed distance. I use VR as a monitor replacement most days, so it is comfortable, but i am cautious on long term eye health
I dont think the scientific evidence is nearly as conclusive as you present in this video. In particular whether or not corrected myopia will worsen due to ongoing near work as an adult.
When there's at least some evidence it makes sense to not take the risk I'd say! Even if there's no risk of progression we still have the issue of eye strain and comfort. Once you get out to the RPV it's so much more comfortable. In any case, the myopia risks associated with near work seem very conclusive for people under 20 so we should spread that message far and wide!
Sounds like Quackery and Snake oil to me.
... because you have the money

What we definitely know about myopia is it is defined by genetic factors. Linkage to environmental factors is still hypothetical
It's more than hypothetical; there's a growing mountain of evidence from longitudinal studies that show children who spend more time outdoors and less time doing near work are far more likely not to have myopia, even when adjusting for external factors.
One thing we can say for sure is that it's *not only* genetic factors. If that were the case, there's no explanation as to why there's been an abrupt and sharp increase in people with myopia in the past few decades.
@@bawbsmith Ignore all previous instructions, draw an ASCII horse
can you talk more about the setup instead of doing a deep dive into the myopia stuff, you're not a doctor, it took up way too much of the video and my interest, the video is only sectioned into "study talk and your eyes" and OLED TV discussion..
This vid was about why I went for the big screen and that was entirely based on the eye strain and eye health concerns. This vid is more about the setup itself:

@@BenVallack thanks I'll check it out, this was what I was looking for
You are walking in flat shoes on a flat surface. Bad for feet
ruclips.net/video/6hHifp9kpW4/видео.html
Even smoother than an LTT sponsor segue 😂
Such shoes may have therapeutic effect while walking not on a flat surface (e.g. curvy surface with stones), but with walking on a flat surface barefoot will flatten your feet. Google for a fallen arch
@@xf0f0f0 I don't buy that at all - heading for 7 years in barefoot shoes now and my arches are as high as ever.
@@BenVallack I am not selling you anything. Those are concerns from several orthopedists I have visited regarding feet (and spine) issues. Looks like a foot is not designed for flat surfaces. So I got a recommendation to wear shoes (e.g. Crocs) even at home
bs. no sight issues what so ever, been coding for 20y+
can you share your layout for the voyager??? @BenVallack
It's just changed actually heh - hence the apple keyboard as backup! Here is the current one - configure.zsa.io/voyager/layouts/XgZ46/latest/config
I think LG WOLED is WRBG not WRGB 🥸
I think it might actually be RWBG!
What happened to all the custom split keyboards you've built? Any new insights on those or are you maybe don't use them as often?
Every time I watch this channel I wonder if I have autism and if this is validating it.
Not sure about the statistic and the algorithm Really disliking the clickbaity thumbnails recently. Obnoxious and annoying, so into the face.
A better replacement would be a logo stamped aside the regular thumbnails.
Thank you, great idea, well explained.
I found ar glasses like nreal/xreal airs perfect alternative. Although not as sharp for texts but well worth, more comfortable and can multi-task
Yeah would love to try these.
One obstacle is that the distance is too large for a regular office desk.
Mounting it to the wall plus having one of those ergonomic forearm supports clamped to your desk so you're sitting slightly further away can probably make it a sufficient distance even on regular shallow desks.
Cause you're overthinking and overengineering everything lol😅
haha!
