I have Glasses, and thought that was a scary video like the scary maze game prank.
Same
As a kid I heard it was a monster and was so scared
When i was having my eye exam my dad told me it was going to blow air into my eye.
It didnt, but i still need glasses
i don't have glasses and i knew about it
I use to have that chart memorized, always wondered why they never changed it.
Because they lazy to reprint the new one...
It depends on the eye doctor. Many eye doctors now use digitized high-res displays, and are able to put any letters or numbers they want on the electric chart. Even the so-called "gold-standard" ETDRS charts, which are different from the "Big E" chart, can be memorized.
When it comes to studies of human visual acuity, the International Council of Ophthalmology requires the use of the Landolt Ring. It is based on the same principle as the letter charts, but it uses only a single shape, which is a circle with a gap (like the letter C) presented in various orientations. The person being tested has to correctly identify whether the gap is pointed up, down, left, or right. It is most commonly used in Japan and Europe. The International Council of Ophthalmology considers the Landolt Ring to be the purest research standard, and requires all studies of visual acuity to be calibrated against it.
but why. glasses is for you it's not about to satisfy doctor. letters there to help you understand how sharp is your vision.
@@armandconiglio9620 that is because letters are shit. Our brain is able to recognise them much better and then when you look onto light & buildings it is all wrong.
@@lolerie Yes, definitely. The letters can even be recognized below the resolving limit of the eye, because of the exterior form of the letters. My favorite vision chart is the Tumbling-E, because of of its grating pattern and the fact that astigmatic errors manifest when looking at the E's different orientations.
Thanks, I've always been curious about how this part of the exam works.
Such a compact and informative video I’m surprised this channel doesn’t have more subscribers
I have glasses, idk what this is. I saw it and thought it was a horror game
I literally searched up “hot air balloon end of road jump scare” 💀💀💀
Its not scary
@@nathanjason369 😂omg
For me it was very blurry so I have glasses
I wear glasses and have never seen this before. The "better or worse" part of the exam my doctor has always used a slide of the eye chart or the actual eye chart on the wall opposite his chair.
Were you looking at the chart through a mirror's reflection?
I was also intrigue at that hot-air balloon when I went to an eye check-up. It is my first time and I am 24. The image I saw is a field with that balloon in the middle, the optalmologist seems to adjust something so i see the balloon became blur or sharp as it tries my eyes to focus on which image it will go clear. (Sorry for my english btw).
After that, she wrote something and proceed to get my eye measurement. Then found out I have myopic astigmatism.. that's the reason why I always feel dizzy, having headaches, and having a hard time seeing from far distance.
Now I know why
that's unfortunate, astigmatism still can be corrected using glasses though. So always remember to wear your glasses when you wake up every morning
haha me too, i am 15 years old and my optometrist told me i developed astigmatism and myopia through my childhood. i will be choosing glasses later today :]
Excellent, informative video.
I am still trying to find out why the cylindrical measurement of my prescription is very unstable.
I am only getting a few months out of glasses before the cylinder changes and I need yet another new pair.
It is driving me mad !!
I had my first pair of glasses 8 years ago. I was wondering what that house was and I was itching to get off the chair. Finally an explanation.
Ghosts came to haunt you.
Vitamin A found in carrots has been linked to improving the quality of night vision, and helps your eyes adjust to dark settings much faster. So I would say carrots help brighten your eyesight.
But what ever you say there is no treatment of myopia i am a boy my age is 13 and i am suffering from myopia since 9 years. But i feel sad and more sad coz why i Lost my god gifted eye
look for the biochemistry of the photoreceptors of the eyes and you'll be amazed that is the same with the molecular components of the carrots. Anyways there are so many different types of nearsightedness so eating carrots cannot magically correct it. It's like saying vitamin E is good for the skin so it can magically eliminate acne.
@@adolinesiam2007 I have myopia too. :( You can get LASIK eye surgery however to correct the vision loss
@@nestorenriquez3284 I'm not saying that carrots can correct myopia at all, but rather improve the quality of your sight in dark environments. So it helps cope with night blindness
@@adolinesiam2007 I have reversed myopia from -2 both eyes to -1 both eyes.Its posible. I have taken triphala , amla , eye exercises to get -.25D reduction per year. So it took me 3-4yrs to go from -2 to -1
It doesn't matter if the air balloon calculates your eye power.
The main thing is that the pictures are full of Nostalgia.
Went for eye test today and was wondering what that house does
Oh and I hate that choosing which is better between 1 or 2 lens during test...they both look the same!!
If u stare at it it's gonna flash REALLY BRIGHT IT MITE HURT THEY MITE TRICK U TO NOT RUN AND A NEEDLE WILL GO IN YOUR EYE BUT IT'S REALLY THIN SO WHEN U DO IT DON'T DO IT JUST SIMPLY SCREAM AND RUN
@@christopherbokar2400 fr omg did you take it?
IT REALLY is not. First of all cylenders must be added first, they usually are not. Second of all letters are a bad test. Try building or some scenery. Or even just letters on a book.
Ikr!!
That's BS, DA.
That barn and the balloon look soooo familier...
Thanks Mam 🙂 Best video I find on RUclips for Eyesight 😌
After having my eye test on this machine , my left eye starting acting weird, does the light from this machine cause any issue on the eye ?
About that stellen chart i am happy now they use random letters because i have memorised it perfectly.
thanks! great informational video
Around age 50, that was when my prescription on one eye changed enough that it warranted new exam. I went online to order the glasses but I started to notice that the visions through the new eyeglasses from both eyes do not line up. My left vision becomes dominant and wiped out the right vision while my right pupil would ‘cross’ to the left as if in an attempt to focus. How can I tell if it’s my eyes that’s at fault or my glasses or the prescription?
I’m not sure but best to talk to your trusted eye doctor
Prescription probably it doesnt cost much I advice you to check with another eye doctor,
Actually some eye doctors in big hospitals just delegate the eye test to Lower people or Inexperienced personnel and then give you over prescribed or underprescribed glasses, properly talk with the test taker and ask him to give a slightly underprescribed glasses in case of myopia. Like its ok if there is a little blur on the last line .
Um, idk, maybe try going to ur eye Dr ? Lol
i did this a while back i dont have glasses tho i just suck at focusing on letters from far away
Sitting at the doctor's and wondering how that balloon works 🤣
How much can be the difference between reading shown by autorefractor and snellen chart letters read with help of glasses inserted in phoropter in incrememts of 0.25D?
It has been 10D for me but not on the same day. Part of the difference for me includes dry eyes, over accommodation without glasses and convergence insufficiency.
The house and the hot air balloon get me nostalgic (yes i wear glasses)
In my area the biggest eye hospital I went the chart is the same I saw 5 years ago...when they show it I know what is written there but how can I tell that I am seeing correctly like other people see...I really don't know how healthy person see that chart
Did one of these and my doctor said I have a disfigured cornea. And I can't fix it.
I never understand the meme about it on the internet until I wear glass......
Thank you for this video
🔥🔥🔥 These fires came while listening 🎧......
I went to the 1st ent doctor because im having headaches and put me snellen chart, left eye is 20/20 and my right eye is 18/20 so he prescribe me eyeglasses because it was eye strain. The headache is gone but i got sinus pressure so i went to another ent doctor for 2nd opinion he put me autorefractor he said my eyes okay no eye grade and check all my eyes, nose, throat, neck. I have sinusitis. Because the 1st ent doctor didnt check my nose ear and throat. The 2nd ent doctor gave me meds for sinusitis and nasolfo nasal spray im better. I also stop wearing the eyeglasses for a week. But i put it back im wearing it now for 2 weeks cause when im looking at far distance without the glasses sometimes it makes me dizzy and my left eye sometime i see eye floaters. Sometimes i experience dry eyes. Should i believe the 1st ent doctor or the 2nd ent doctor? Thanks
When I was in class 7th I wanted to get rid of my glasses
But today I am 19 and I wish my vision could be corrected with glasses but it can't because I have keratoconus.
I have myopia L>-2.75 R> -2.75
And I am 20,And you're saying this never gets better and I need to wear this all my life
Is auto reftractometer gives accurate error values?
NO!!! Even some opticians will admit this.
Nice video mam..my right eyes so weak I have plus no.6/18 And also color blindness. How I can improve this my eye sight please suggest me mam 🙏
If you spend a lot of time reading or in from of a pc you may need to remove the spasm of accomodation which can be big. That is done with atropine or phenylephrin. Then you need to measure your accomodation and use beta memetics to increase it. And then you can use contact lenses for some time to stabilise your vision, usually second month contacts are correct.
I gave up on automatic tests.
Now, I use my own Snellen and Test Lenses.
That is how I got my 20/20 vision back, from 20/50.
It took me a year to do it.
How??
Sir can you do me a favour and tell me the process
@Otie Brown can you tell us the process please ???
??
HOW
You need to freeze accommodation to get accurate measurement.
If you use an Auto Refractor.
Use a trial lens kit for accuracy.
Exactly, I work as a software developer snd every time I use a auto refractor it says -1.5, but when the doctor freezes my accomodation it is close to 0
@G E T R E K T Exactly, this is why so many people end up highly myopic. I see poor 7-9 years old children wearing mild prescriptions of -1 while usind the mobile phone and reading. They will sadly end up with prescriptions of -6 as adults because the optometrists tell their parents to wear the glasses full time 😢 12 years ago I ordered three trial lenses kit to check what is the minimum prescription I need to be able to see perfect at night for driving when I am tired. It was -0.75 for my left eye and -0.5 for my right eye instead of -1.5, when I am relaxed -0.5 is enough. I ordered the glasses on zenni website with -0.5 and only wear them at night when I drive. When I read and use my phone I use lately +0.5 glasses, I feel my eyes much more relaxed and maybe I can fix my accomodation stress 🙂
Hi Get,
This is why I use my random cell phones Snellen.
Thanks this video give me motivation to wear eyeglasses now
I saw this in a Reddit compilation video and didn't know what it was literally searched picture of a farmhouse and a weather balloon on a road and this came up poggers
This just happened to me today, but with the house instead. I was wondering what the doc was doing

I'm getting glasses soon!
I remember my mom told me to eat raw carrot for a year because she "heard" a child was magically cured out of myopia 😂😂😂 she also purposely undercooked carrots which made them taste bad. I hate carrots ever since.
cooked carrot taste bad but eating raw or frying together in a fried rice is good tho😅
@@SmilyMmn ewww raw carrot. It's bland and hard.
Are you Indian??
@@sakshipatil5155 indonesian
@@Min-es6wv seriously? remove the outer part of carrot and eat it...or you can make salad and eat it by slicing or using the kitchen tools 😁😁 I really like it especially if it's 99.99% natural...still not that much natural also I eat🤣
Very good video
Always wondered about it
Hey thanks for the comment! Do help us spread the word about it and share :D Thanks for enjoying and sharing our content!
@@Vulcanpost Ma'am please reply me. I'm 17 and I wear glasses of -6.00 and -6.50 and I am wearing it since 5 years. It is gradually becoming worse since past. Will it ever stop or I will become blind one day?
What about progression of myopia after 25
@2:47 should the image of carrot be inverted after passing through the lens?
What do you mean? Do our eyes see inverted images?
@@farwahbatool6247 Yes indeed!
@@colorklimax oh, i must have forgotten my lessons 😲
the letters I read don't get randomized and I memorize the letters.
Oh gosh i had to do all those tests 😭
I dont know how to thank you....thank you sooo much
after this exact eye exam in the video wheni got home my eyes were hurting like hell. they were straining.
Yes that can happen, because the image is no more than 18 inches from your face which can be really close for some people without glasses on. I have the same problem but you will find that opticians disregard this.
I have PD VALUE of R 30 and L 31.5 But My glasses PD value is 31.5 each will it be a problem??
You’re good. Any variance between 1 to 2 millimeters in a PD is deemed, in general, an acceptable measurement. However, this depends on the individual. I’ve seen some people with a PD of 33 in the right eye and a 30.5 in the left. What is more concerning is if a patient isn’t properly measured, and the PD is way off, then this can cause distortion in your vision, double vision, nausea, headaches, and prism. But 31.5 in each eye is fine.
That shit was scary, especially the air part… now I have glasses
I never had glasses but I know this picture! 😂
I took my eyesight drivers license test today and I can't even get pass the first level, then I went to see a eye doctor today and it says my left eye works better than my right eye and my right eye has poor vision and that I needed glasses in order to get my drivers license
Finally , Someone understands what I try to say, People without glasses can't understand these things
Lol, I have Astigmatism and dry time I go to the opticians I see the hot air ballon one
2:20 about these colors, my old doctor gave me glasses just because he asked which color is brighter and I said green
As a kid, I always thought that the doctor used to hypnotise me
It is very ASMR
I had -- 5 in each eye, but fixed this in a natural way without surgery or lenses, doing vision exercises, Now I have only - 1.5 but I want to improve even more
I have -4 .please tell me the natural way and vision exercises please please?
Can u tell how u fixed it?
not possible
Nice joke
How u did that i badly need it
That farm house I recognize all to well, the hot air balloon? Never seen it
But people keep talking about how they got ptsd from the pictures, like itscared them or idk
Re Hot air Balloon test - the video totally fails to say how it measures your eye. Projecting an image into it, does nothing itself.
I took my eyesight drivers license test today and I can't even get pass the first level, then I went to see a eye doctor today and it says my left eye works better than my right eye and my right eye has poor vision and that I needed glasses in order to get my drivers license
Thanks
Probably way too late to ask this but is there no test in a regular eye test to test for astigmatism because it seems that it's contributing to my bad vision and wasn't looked for whatsoever
I thought testing for astigmatism is a standard procedure when getting your eyes tested? I do have astigmatism and the optometrist tested for it during the Snellen Test. I had to look at circles somehow and tell them how distorted they looked. Also whether the image gets sharper or not.
@@ElectricHeart well I definitely didn't get that lol cool
@@hhhhhhhhhhhhhnhhhhhhh I'd file a complaint like wtf this is outrageous and they didn't do their job properly
That Hut is nightmare to me. I was 15 when I get my specs and there was -2.5 on my left eye. I was literally crying. That Hut is nightmare true
Mistake at 2:41
Image should be inverted on retina.......
Explain
I have glasses, but idek what the trick that is
my old option only used that to get my prescription, not factoring the fact of my VERY stolen optical nerve which he ignored
Ummm....what??
Can I do myself at home
When you putt your eye in the autorefractor, does it hurt?
No
No
i didnt even see the channel’s name at first but i can guess the accent is malaysian 😅
I remenber one time i did a test with the ballon and i hoestely had a hard time focusing on the picture
My eye was just really unconfortable
I am longsighted and that used to be my experience. The last time I used one I made sure NOT to focus. To be honest, the Snellen chart gives me a better result as my vision is a bit unstable.
You're not supposed to try to focus. Just stare.
Thank you for stating the obvious that the air balloon test tests your vision. Needed this video
exactly like this is such a useless video lmao
Does this test read retina too ?!
God bless you now and always Dr Omole on RUclips, Just wanted to say a big THANK YOU for helping me cure the herpes simplex virus I was facing, I thought it was the end not until I met you, I will be happy to recommend you to other people around the word.....
I have Myopia I was not happy :[
20/20 vision
I never been eye dr.Pluss I won't be able afford it.same with a physical. I am 41 and never had physical as adult because I can not afford treatment and I would reject all treatments and just let the problem kill me like my friend.he never went to dr. Till he was older.he had diabetic and had no insurance our money pay for treatment he just let him self die.Nowadays,you need a lot money and great insurance for all this and not everyone like me have insurance because I can not afford that pluss I tryed getting state they denied me every time.If my sight changes,well I am screwed lol
Oh it doesn't. For me difference between objective test can be anything between 1 and 10D. The last time that happened I was treated straight out like I was lying.
In Turkiye, our images are more realistic but the same ones anyway! Especially the house one lolol i’ve been usşng glasses since i was 7 so the eye doctor is like my second home dude. I just know whats gonna happen everytime so the doctors don’t even need to tell me what to do.
It always makes me embarrassed getting new prescriptions knowing damn well im failing every test
it's not a test you need to do well on, if you do well you wasted the doctors time
I have cylinder -0,5 in both my eyes, should i wear glasses?
No.
informative,
I’ve been to the opticians so many times I memorised the old stellen chart
You made the diagram wrong for the elongated eye ball @ 2:43

Please help
I went to doctor a month ago, he prescribed me -.75 on right eye and -1.0 on left eye..
Then I went to shop for ordering eyeglass, I also took the eye test there and it turned out -1.25 on both eyes, things were sharp as hell, perfectly clear.
After wearing that glass for some times my eyes felt little sensitive.. so I went to another doctor again.. then he prescribed me -1.0 on both eyes.. I mean wtf.
What should I do?
Docs generally give -1 or -.5 D lower than your prescribed value besides -1D isn't high enough to cause alarm.Mine is -6D

Like if the doc says wear -1 in both eyes then -0.75 glasses would be the optimum
@@kdreamscosmos4279 and dont do close up tasks on the day of eye test, unless you want your eyes to be tired with ciliary spasm and get overcorrected glasses and you with overcorrected glasses we think that because these are new glasses thats why my eyes must be adjusting the headache is good and headache will go away in few days and book your power is increased so much .
Myopia happens by some intense close up work, what is the root cause of astigmatism?
No, it does not. Were you even taught at school? It never happens due to that. It is purely genetical and caused by wrong eyeball form and so cannot be corrected (even by lasers, that is just a hack). Astigmatism can be fully corrected by lasers since that is caused by the part lasers destroy.
@@lolerie how myopia n hyperopia not be corrected? I confirm that I got myopia by doing some closeup work for one hour, 3 years ago. Doctors too blindly follow what is written without having proof, brain and experience
@@Krishna13847 for one hour? Are you trolling? Again, miopia progresses until you are 25 or something. So that has nothing to do with eye strain. There is this thing called spasm of accomodation. You can get 0.25 or more just from morning to evening.
@@lolerie I am not trolling, it was the first time I played a phone game for an hour so much closely. And why it can be corrected? I tried to clear the blur for two years, but the myopia increased and finally consulted a doctor
@@Krishna13847 did he gave you anything agasint accomodation spasm? But 1 hour is nothing. I spend 13 hours behind the screens. So... I got bad accomodation spasm and then fixed it. It is almost as bad as it was 4 years ago now, while it was 2 times worse with spasm.
I told my optician the red was more brighter than green. He checked me again with the auto refractor😅
If green appears clearer, then it means that you need more minus power in your prescription.
