if you are actually seeing it, it will tilt as you tilt your head. For me when I looked through the polarizer I saw blue the brightest and yellow was faint. But on the screen yellow was the brightest. This may be different for different people though.
cool
For me, I see the yellow brightest and blue after I see yellow
Humm. 🤔👍
I see it as light yellow
Yep
Me, on my phone: I'm sure that was cool.
I could see it on my phone
Barely
You could orient your phone to make it work. If you have polarized sunglasses, put them on and rotate your phone until it dims or turns purple. That's the angle you should try to see this "brush" at
I am on phone I see it it doesn't change lol
@@EfrenMunoz313 most phones do not use the polarized light anymore.
They use oled's that are directly viewable.

Me: No, but I will blame my monitor.

I see it
I have two monitors. I can see it much better on one than on the other.
Same
I see it it's a yellow line going in-between two light blue dots like a plus sign
With the particular presentation in this video it's also possible that you're going to see a persistence aftereffect from having stared at the yellow and blue nodes.
This indeed seems to be the case -- after he quit showing the pattern, I saw it rotated 90 ` for several seconds before it eventually faded away.
Real Haidinger's brush has an unbroken yellow part, and broken blue. When you tilt your head, its orientation won't follow your eyes. A negative afterimage of a picture of Haidinger's brush has an unbroken blue part, and broken yellow. When you tilt your head, its orientation will follow your eyes.
@@magentamonster . . . And that's what I got.
I thought so too, but as I rotate my head one way the 'brush' rotates the reverse.
I got the afterimage from staring at a fullscreen Notepad and then tipping my head -- didn't notice much while my head was upright, but a strong yellow when tipped. I presume that means I'm seeing, but not easily perceiving, a blue while my head is level?
The last time I was at an eye doctor's, I was able to tell the screen they were using was polarized because I've discovered that one of my eyes starts hurting when staring at polarized light in a dark room and everything starts to look weird with that eye.
I hope you told your doctor about that

I've seen this around lights constantly since I was young. Around 12 years old I told my mom about it because I thought there might be something wrong with my eyes and she (being a spiritual lady) told me I see auraa. It's neat to have a scientific explanation for what I'm seeing, because I've never shared her spiritual explanation.

As a child, I always stopped and stared at the puddle in the parking lot. The oil on the top made a polarizing effect. I tried to explain it to my parents, but they couldn't see it.

It’s important to note this might not work in OLED screens, as those don’t need to use polarisers. Furthermore, screen protectors usually scramble the polarisation due to them using a thin plastic film (if you look at a screen protector through a polariser you can see random multicolor interference patterns).

Had to turn my head down 90 deg to see it better, but its there, about 1/2 the size of the one you started with.

It's neither the color nor the pixel depth, it's the polarization effect and your ability to discern it. In fact the pixel depth is super irrelevant to this one. One giant pixel would do the job just fine. And as for colors, I would *imagine* that the exact same effect is there no matter what, but the color of the light would wash out the effect to the degree that that color interacts with yellow and blue, so if the light was bluish, the blue region would disappear and the yellow region would take a greenish cast...but everything after the word 'imagine' is just speculation.

Apparently, if you were randomly dropped anywhere in the United States, you can use the filters in this kit to determine if you're in a blue state or a red state. 😉
@@Robert41265how do swing states then
@@wilyriley_A swing state would be unpolarized. 😉
Wow! I couldn't see it at first, and then I got the test image to look more bright, so I tried again with the actual white image and I saw two yellow dots flip sort of diagonally! Cool stuff.
Optical Engineer here, a lot of the light "information" here is not right. For example, metals do reflect and polarize light. There is a whole field of measurements "metrology" dedicated to thin films and metal polarization detection also known as ellipsometry. Linear polarizers dont work on circular or elliptically polarized light, instead, you need a retarder (compensator), quarter wave plate + a linear polarizer to resolve the polarization of light coming from a metal.
I’ve got the retardation and compensation covered.
Engineer here too. Happens all the time when you get a great education 😪... The "news" is The Worst
I'm no engineer, but I appreciate your comment a lot. The video shocked me a little when the metal film didn't get blocked by the linear polarizer. I thought to myself, "does this mean that metal doesn't polarize light when it reflects? There seems to be a contradiction somewhere."
Then you came into the comments and helped clarify it. Thanks.
Thank you for taking your time to explain it.

Who is macula and eye floaty
@@makhtydh, The macula is a part of the eye, and an eye floatie/floater is a little spot you can sometimes faintly see in your vision.
i can see it! did take me a bit of time, but yeah, i see it way better when i tilt my head 90° to the left or right, it's way more subtle when i try to see it while keeping my head straight.
that's not retinal persistence with the model at the start of the white screen test, because i skipped this part to not influence the test and tried some minutes later to be sure.
i tried on my brand new smartphone (amoled) and i can see it too.
i noticed that the brush rotating in the OPPOSITE way when i tilt my head, if i tilt it to the right the brush will rotate anti-clockwise.
that's very fascinating!
I actually noticed this when looking at computer screens more that a decade ago. I searched for “blue and yellow blob in vision” and got my answer. It’s always fascinated me that some (or most) of us can faintly detect not only polarized light, but the direction of polarization. Really cool. A 6th sense.
Me: "I can see it, but the blue is horizontal." Video: "Which direction it is depends on how you're tilting your head." me, laying on my side: "Well there you go then."
You see blue?
That’s the polarization of it
@@lionessfit3041 I also saw blue
That happened to me too
I see both of them. Doesn't change when I turn my phone or tilt my head.
Yellow: Horizontal
Blue: Vertical
I remember an Inuit guide describing a similar vision that he used to navigate in the snow. I was so crazy how these guys could get around in wast expanses of white with no landmarks before GPS and compasses were very bad in the Arctic.
You mean, like, being able to see magnetic fields?
😲
@@AGKyran They see the polarized light in the snow and can tel where the sun is on a cloudy day. There are special goggles you can make that will do this too.
Vikings used a sunstone.
That's awesome
Pretty neat stuff. I use cross polarization all the time on VFX projects where we need to control which lights are producing specular highlights on objects that are going to be comped in with 3D animated elements. Each light source will have a polarizer that is aligned specifically for that group and the the camera lenses will have a circular polarizer that can be adjusted depending on the lighting group that is needed.
That's really cool. I never would have known that was something other than light play. Mine was 20% the size of the image you showed but visible.
This is perfect timing! My wife and I were talking about polarized sunglasses and our kids asked what polarization is. This video explains it better than I did so now I can show them this!

If you orient your sunglasses correctly,
*Rotates head*. .
Driving 10/10
The sun is usually above our heads, so all the polarized sunglasses just block glares from right above sources best and do a decent job when the source is slightly to the side.
If the sun is below your head you might better be slightly concerned about your car being upside down.
👏🏼👏🏼👏🏼 Amazing!!!
I always thought that was something on monitors, I never thought that's something about vision.
I thought the yellow part was the light source of the screen and the blue part the areas where were not well lightened.
I was looking to the phone and tilted a little, this gradient pattern doesn't fit the screen, because it was bigger, but it changes direction, going to the opposite direction from where I started to tilt.
Love this experiment!!!
Me first seeing the polarizer in action: Wow, imagine if there was like something you can wear that would just block all the glares on screens
Me like a few seconds later when he gets to the phone: Crap I just accidentally reinvented sunglasses
All I could see was how dirty my screen was when I watched this on my TV.

I have one eye through which I see clearly, after having 7 ops on the other one for retinal detatchment which see but doesn't focus. So, I can see tons of yellow but not the blue, and that's with no sunglasses. Thanks for sharing this, I saved it to favourites!
6:56 ooo.. what you’re talking about may be why I have great peripheral vision. I have always practiced seeing without moving my eyes or head. It helps so much to be able to look forward and in your side view mirrors (or rear view mirror) simultaneously when driving. Maybe this is different, but it sounds like it is using the same technique.
Family caught me staring at a white screen with my sunglasses on. Thanks Action Lab!
Congrats
Congrats
I thought I was special till he took the image away.
5:17 The normal orientation, it's invisible, but I imagine the starting point is that the yellow line is vertical.
If I tilt my head left, the yellow line tilts right, and if I tilt my head right, the yellow line tilts left.
It's possible that it's invisible to me when level because I'm used to looking at this screen with a level head, so my brain just filters it out.
I'm gonna second the brain filter theory
I can see it while tilting my head, but only while my head is moving
Once I stop, it fades away
Oooh thanks! You actually helped me see it consistently. I was beginning to wonder if I was just seeing things because I would see it faintly for only a split second at a time.
Ooooohhhhhh!!!!! That explains something I've always experienced! In some lights I've seen yellow or blue auras...

Great, another thing that I can't un-see. Someone showed me how to see all the "floaters" one day, now they're with me for life.
For me floaters are kind of like the game. You only lose if you think about it. By the way, you just lost the game
Wait you can purposely see floaters? How???
@@doesntmatter2732 Try looking at a big fluorescent black light bulb (regular, not blue-black) for a minute. You can also see them against the blue of the sky, maybe not quite as well.
@@doesntmatter2732 I guess I should elaborate a bit, we were all tripping one night. A few of my friends were over by the black light, "Can you see them yet?" "Whoa!." I had never heard of floaters, but after looking at the light for a minute or two, I suddenly saw them as well. The sun was coming up, when I went outside and looked against the blue of the sky, I saw a whole bunch of floaters, from that day forward, unfortunately.
Once you see them, you can't unsee them. Are you absolutely sure that you want to see them? They have always been with you, but you block, them out, like background noise. But after you notice that spot on the wall, you're might see it the rest of your life. Are you _sure_ that's what you want???
I rarely see floaters, but it's nice when I do. Wouldn't wish for anyone to see them all the time though.
But after taking a lot of drugs during about 4 years, I now have phosphenes all the time.
I mostly see them at night, it's very easier to see them in dark places.
And it's cool. If you start focus at them, they may start to change and make shapes.
The more I focus on them, the more they get detailed.
It's a fun thing.
Also staring for a moment dehydrates your eyes.
You can play with it by fixing the ground. It works better on clear repetitive patterns.
When you do, it then starts to move.
I've done that again recently (don't do it too often!), and it looked like ripples.
It's quite awesome.
Also, learned the trick where you stay in the dark, and turn on a light above your head on the side of your head.
Makes you able to see the blood vessels in your eyes, like a web (it will be in a dark gray most likely).
I noticed is I could see it better focusing slightly "behind" the screen instead of focusing right on the surface of the screen. Also, I have 2 monitors and the angle of yellow/blue cross was different on my older IPS monitor (blue band horizontal) vs newer VA monitor (blue band more vertical), absolutely nutty!
While I didn't see the Brush, I did get the thought to turn my polarized sunglasses and WOW when it dimmed that white background (at around 45 degree tilt) I saw all the spots on my monitor!
Thanks for this new tech.

Yes. But if you are being honest it in part is based on the quality of the screen you are using.
Test like this is not usefull if it wasn't played on same display or on paper and people looking at it from same distance and angle,but it fun tough
@@HanisExperiments you are everywhere

This title was like those old 99% CAN’T SEE IT videos on RUclips, but the difference being that this video is better then 100 of those videos put together
Looking at this on a (not super modern) Galaxy S22 from 2 years ago from when I'm viewing this video, you can see it if you pause the video and hold your phone in landscape, then look at the camera cutout dot and move the phone backwards and forwards until the centre of the video is around about where your ocular blindspot is (where the ocular nerve is, like those old tests where you put 2 xs on a piece of paper and move your vision forward and back from it)
So the spot shows up right around where your normal blind spot is
So stare at the camera cutout, close the eye closest to the cutout and move the phone forward and back slowly until you see it.
If that's hard, look at the image with your clossr eye and move the phone until the camera dot disappears, then open that eye and close the other eye
I can see it perfectly without the polarizer.

I GUESS I'M A SUPERHERO NOW MOM TIME TO DECIDE A NICKNAME
i think everyone or almost everyone can see it but if you are actually seeing it he said that as you tilt your head you should see it tilting too or something like that which doesnt happen to me
I’ve always been able to see this. This has actually been a problem though. LED headlights really mess with my eyes.
I used to see that RIDICULOUSLY often on the back glass of cars after I tried my dad's sunglasses for about a week I could see it for MONTHS at a time, about 4 months, before the effect seemed to taper off.
I have the same issue. I might buy those night driving glasses that block the glare from bright lights. The LED lights completely destroy my eyes.

Y'know, this would be *really* interesting if he actually explained what polarized light is! :D
Light in nature are made of oscillating pairs of magnetic and electric fields. Normal light is
like tons of those pairs of waves he showed, but all mooshed and close together and tilted
at random angles from each other. Imagine lots of fish randomly swimming serpentine in
one direction, but some are upside down, sideways, etc.
The polarizers he had are like microscopic window blinds. When the sun shines through your
blinds, some light is blocked and you get parallel lines of light on the wall or whatever. Polarizers
block all the light waves that aren't parallel to the little blinds on the sheet. So, if some light
is LINEARLY polarized, then those polarizers will let it through if its wave can slide through
the polarizer slits. The light gets dimmer if it's not lined up perfectly, and gets blocked when
the wave is perpendicular.
I was waiting the whole time for him to explain it or point us somewhere we can learn about it lol
@@willbe3043 It just takes a second to search it on RUclips tbh

Remember reading in a book a suggestion that vehicles could use polarised lights & have polarised windscreens to help reduce glare, always wondered if it would work. 🤔
Me: trying to see it
Video: "it occurs in the macula"
Me: with swollen optic nerves "ah."
Ahhh, that makes sense
I guess I should save this video as an amateur eye test for inflammation...
It looks pretty viewable (if that's even a word), I was able to see it clearly, not clear to the point of where it's not blurry, but it's clear, the white light altough starts to block me from seeing the blue part after a while.
This video has just reminded of an experience I could repeat as a child, before puberty I think.
I would close one of my eyes (forget which was which), lets say the right eye, so the left eye was open. With just the left eye open, I would experience a slight yellow tinge to the world, and if I swapped them, the right eye would experience a blue tinge.
I remember telling my mum and she wasy just like "oh OK." Her response to anything I said really lol
I remember doing this and thinking that this was just how vision wworked, and when both eyes were open they complemented each other and the world appeared "normal" or "regular."
I just tried this again now, and I experience no difference between my eyes. Probably due to UV yellowing of the lenses of my eyes as I have aged.
I don't know if this has anything to do with the effect described in the video, but it is interesting that the effect manifests as blue and yellow.
Anyway, nice memory lane trip to go down. Don't know if anyone else has had a similar experience. Would be cool if someone out in the internet wildlands has seen the same thing.
Thanks for reading.
It worked on my desktop screen just by opening a blank file. wow!!!
But: I had to turn the brightness all the way up to 100 (I usually have it near zero to stop headaches), I had to take off the "nightlight" blue blocking option, and I had to tilt my head VERY slowly. It's more of a "ghost image" type thing, like an afterimage from looking at a bright like....or one of those Magic Eye pictures...but also not quite that. The yellow was mostly horizontal and the blue vertical but it did move a bit along with my head.
Science is so fascinating omfg ❤
*bright light ugh typo
this is what they use on cameras while filming shiny surfaces
It's amazing how much and how little you can see with your own senses.
I wear glasses, and could not see it at first, but after re-watching I heard you said it can depend on the angle of your head, I rotated my head and I could see it so clearly!
I'm assuming my glasses must mess with the polarisation in some way...
First I didn't see anything but the afterimage, but after some tries I got it to work. For me the yellow bulbs are horizonal and they actually tilt.
I have a blind patch in the center of my right eye from a pulse laser accident 5 years ago and it still exists. I've gotten so use to it I don't notice it normally unless I'm looking at close lines, grids or anything like a window screen or blinds. The blind spot distorts those things and reminds me of an event horizon. I can't say the spot is black though it's nothing like a dark spot, it's just distorted absence.
What he meant by "Not Everyone Can See" he meant people with their blue light filters enabled.
Is it odd that I saw both with and without the blue light filter enabled (LG v50 Thinq)?
I have my blue light filter on and I saw it
You guys might have it at a lower level.
I turned off my blue light filter for this video and saw nothing. I even checked with my polrised sunglasses that my screen is definitely polarised, but I can still not see it
Nah he meant that some people are physically incapable of seeing polarized light.
Years ago, I had a pair of sunglasses that were both polarizing and UV filtering. Because of this, it could block the glare from some things, but the from the things it couldn't (sun glare off water) had this day-glo royal purple halo. Very pretty, I miss them.
I saw this effect a few years ago in a similar experiment 😊
I can see it, its smaller than I expected. I could only see the horizontal yellow.
Once I could see yellow, I tilted my phone very slightly left and right, then the blue showed up just barely.
Same here. When I tilt my head left and right the yellow bar rotates a few degrees as well. Very interesting. Now I am going to be seeing that all day as I work at my computer.

Because then it moves in relation to the center of vision and changes in vision are always easier to spot for me.
This man had me pausing and squinting at my screen so hard!🤣🤣🤣👌🏾
I accidentally discovered this a while ago, but I thought it was just my sun glasses being funky. Had no idea this was a normal thing. Super cool.
Video Idea: Do the opposite where you show how to find your blind spot by closing one eye, extending your arm, stick out your thumb, and move it away from the center of your vision until when you wiggle your thumb, you don't see it.
Why don't you show us instead 😁
@@bilalejaz1682 Vsauce touched on the blind spot of the eye here: ruclips.net/video/4I5Q3UXkGd0/видео.html
you just explained it, now, why we need a video
POV: you can both see the blue and yellow at the same brightness regardless of orientation
*I am several universes ahead of you*
We are the almighty powerful with our eyes
I am only one universe ahead of everyone. I can do this, but only for blue
I can see both and see which color is overlapping even if the image is blurry
I was actually able to see it on both computer screen and newer phone, it actually showed up better on my phone than on computer screen.
It's faint, but it's really interesting to see on my tablet screen, and what convinced me it wasn't image permanence is that what I was seeing was rotated 90 degrees compared to the example, and also worked after a bit of a break, plus, it changes the orientation based on how I rotate the tablet, very cool : )
me finding out not everyone can see this:
visible confusion
When I tilted my head nearly ar 45° I was able to see that thing , though it was faint. But I saw it!
Thanks to you!
Yup, I can see it on my phone's screen when it's vertical... very cool, thanks. I just realized I've seen this on my monitor before but didn't know what it was.
Very cool! I’ve probably got some disease, as I saw the yellow bulbs only, they were above center, very small, and they rotated the opposite direction of how I would tilt my head 😂
i thought i couldn't see it, but i tred tilting my head in front of my monitor's white screen and then it popped out super clear :O
The action lab is like my number one place to go on RUclips cuz he actually makes interesting stuff
I saw a very light red horizon but it took up my whole screen (what does that mean?). it was neat to see it tilt as i tilted my head side to side
Right so i can see it on my phone, and yes its not very new. Although it was only for a short time adter the image was gone. It wasnt really a cross, but more of a diamond shape. The colors were more faint as well, but that was pretty cool, had to get pretty close with my phone as well
02:00 seems like he himself made a phone stand
which alone would be a content for other DIY RUclipsrs
