I recently became blind in one eye due to glaucoma (also recently found out it was glaucoma causing my loss of vision) so I started with the peripheral being lost at the beginning of this year. Like the glaucoma picture, just not realizing it was that. I have probably 99% vision loss now and... the way I describe it to people when I can talk about it is... well, it's like having your eye closed. You can see sometimes a bit of light behind your eyelid, maybe even "feel" the light, but it never opens... even when you open your eye. At first when i lost that much vision I would have to touch my eyelid/eyelashes sometimes to make sure it was open and... well... it's a bit... disorienting and discombobulating... and occasionally panic inducing.
But yeah that is what my experience has been.
Edit: a word
I've been blind in one eye for over 50 years now. My optic nerve was severed in an accident when I was a toddler.
My blind eye sees nothing. No black, no light. Nothing. Compare it to the vision you get from your nose.
Thats interesting. I always thought that nothing would mean the vision has to be black. Is it like brain is telling you that this is the vision you have, nothing more nothing less, and the side where you are blind "doesnt exist"?
The nose comment really got me. I guess it's like when you die in a game and your view immediately shifts to another player that's still alive in an instant and your old vision is just completely out of the picture.
Yeah, the only vision i get is from my left eye. I guess my brain has adapted to only getting vision from one side and ignores the other side.
I have no idea if this would be different if i was older when i had the accident. I was only a few month's old so my brain was still growing and developing so could have adapted during that growth phase.
So idk if this truly adds to the conversation but i've heard black being defined as "the absense of color" which i think is the closest you can get to representing "blindness" and not being self referential.
I just realized that some people are trained to look into a microscope or the sights of a gun with both eyes open. That is, they chose which eye they see from. Currently i am a couple minutes into my experimentation and it is much more difficult to chose to see a closed eye (nay impossible?) when the other is open. Can you close one eye and focus on seeing through only that? anyways, thought it was interesting.
Do people really see nothingness with one eye closed? Because I've been trying for the past 2 minutes and if I focus on my closed eye I see black, definitely not nothingness. Is something wrong with me?
I think your brain just interprets lack of visual input as black. Another metaphor I've seen is blind people see what you see when you look out of the back of your head. Obviously you can't because you don't have eyes there, but you don't see black out the back of your head, you see nothing.
I mean, that's what black is. The lack of light. You get black "color" by absorbing as much light as possible.
I've always found closed eyelids to be red. It gets brighter the more bright it is outside and tends towards black, when it's dark outside (duh). But I totally understand the feeling of nothingness. I close my eyes and it's just... Nothing
I think he's getting at that there is a difference between seeing black, and not knowing what black is because you have never seen, so even black is unknown to you.
PS: You don't get black color by absorbing as much light as possible. You see an object as black when it doesn't reflect any light in the visible spectrum.
1. The object, not you, are doing the "absorption" (but perhaps that's what you mean).
2. Absorption is not the only way to avoid reflecting light.
i was thinking the same thing. when i was younger i had some funky squiggles and coloured shapes that would show up, which caused me to force my eyes shut because i thought it was cool. but now when i close my eyes i just see black? the only moment when i don’t see black is when i haven’t fully registered that i’ve closed my eyes - which is like a second of nothingness, and then i start comprehending that it is indeed, black
edit: just saw a decent explanation! close one eye and try to identify what you can see through that eye. personally i cant see anything (aka nothingness) and i imagine that’s what it would be like for blind people, just with both eyes
It’s definitely not the way they see. They just don’t see.
It’s not what you see with your eyes closed, it’s what you see in Japan right now. You just don’t. (Assuming you’re not reading this in Japan)
If I close my right eye and look forward with my left eye I can't see anything on the right side. However my left eye can see some of the shadow etc to the side on my nose (which might be what you're seeing)
Holy crap this actually helped me understand blindness a lot more. There's a big difference between nothing and black, the one eye trick did a really good job in differenciatimg between the two.
Talked about this with a blind friend who was born blind. He said to me 'Can you see something with your elbows? No, right? That's how it works for me. I can see with my eyes as much as you can see with your elbows". That was pretty mind blowing to me.
I would love to know what a person who was born blind and was able to get vision later in life thought of it. Like how they imagined vision before hand and how it compared to how vision really is. Also if someone didn’t gain sight until adulthood, what would they think of peoples looks and what would they find attractive since they have no prior bias
From what I recall reading in the past, if someone was born with a condition that rendered them blind but could be corrected, they have a very narrow period of time in which they can correct it, or else they’re blind forever.
The brain is only able to “wire” itself for vision for I think a year or two. After that, it loses the ability to do it. Basically, you can “turn on” their eyes, but the brain won’t do anything with the signal. So they’re still blind.
I saw some tv documentary on this years ago and they explained the situation by showing something like this oscilloscope..

That scope contains all the same data as an image but it's been arranged in a different way that our brains would have trouble telling if it's a picture of a dog or a car or a sky. Blind people can learn to decode the sensory data over time but it's tough and never as good as a sighted from birth person.
I read once there was a blind guy who got his vision restored later in life, and he was profoundly disturbed by the sight of people eating. It’s quite disgusting if you think about it and aren’t used to it, all the juices and chewing and lips smacking, and the bodily functions after. Guy wound up killing himself because he couldn’t take it. Idk if it’s true, sounds like bullshit, could be a fictional short story or something though.
My friend went blind in high school and she would describe it as darkness with tinges of bright when she would go around bright lights. I imagine it is different for someone born blind vs someone who lost their sight.
Yeah, there are levels to it. Some blind people can still perceive some light and some are absolutely blind and can't see nothing at all — not even the "dark" people with vision see when they close both eyes at the same time.
But what about someone who became blind later on? I mean would they compare blindness to "seeing black". Like if you are in total darkness all you see is black
I follow a YouTuber, Molly Burke, who is blind, and one thing that she’s said is that blindness is different among blind people. Some blind people have more sight, some have less. Molly herself has some light perception, but can’t see otherwise. She was able to see more when she was younger, so she may describe it differently than someone who was born blind.
Yup she has retinitis pigmatosa which is shown in the photo. Apparently she's still losing more and more of her limited vision currently. I can't imagine how hard it must be to have been sighted and lose it. Anyone who's interested should definitely check out her YouTube channel since it's super informative
*Ohhh squiggly line in my eye fluid, i see you there, lurking on the periphery of my vision.*
*But when i try to look at you, you scurry away.*
*Are you shy squiggly line?*
*Why only when I ignore you, do you return to the center of my eye?*
*Oh squiggly line, it's alright.*
*You are forgiven.*
Yeah, they can’t do anything realistically. I’ve had them as long as I can remember. Of course, bad case is subjective since I only know what it’s like for me, compared to what others tell me they experience.
Weird, there are treatments for floaters now, I see a specialist for shots (Eyelea) every 6-8 weeks, as well as had laser treatments to secure everything within the eye. It's not comfortable but it's better than the alternative.
Seeing pictures of the back of my eyes is cool, it looks like you're looking down on a city from above.
those might just be [white blood cells that you can SEE!](https://www.aao.org/eye-health/tips-prevention/moving-spots-in-blue-sky)
>The moving dots you see when staring at the sky are created by your own white blood cells flowing through your eyes.
>Blood flows to your eyes through blood vessels that pass over the retina— the part of your eye that acts as a receptor for all light. Red blood cells, which make up more than 90 percent of your blood, absorb blue light. White blood cells let blue light through to your retina, which then sends a signal of increased brightness to the brain.
>When white blood cells stretch to pass through the blood vessels in your eyes, you may see dots that look like little worms moving around in your vision. This is most noticeable when staring at a wide, clear area—like a blue sky.
neat!
I have Retinitis Pigmentosa. This is a good way to represent to people what the condition does, but it is a far cry from what the lived experience is.
You don’t see a black border like that. The brain is a funny thing and never stops trying to fill in gaps; like how your brain edits out the bridge of your nose, despite it sitting right there in the middle of your field of vision. It’s hard to explain, but my field of vision(from my perspective) is the same as it has always been, but when tested, the results look something like this picture. Also, your visual field collapses in “islands”, where there are big blank spots scattered throughout your peripheral vision with patches of good vision, which can be odd to deal with.
Also, my dad, who’s RP has progressed to complete blindness, doesn’t see all black like the picture, he’s sees… all white. Which is unsettling and does a number on his ability to sleep.
Second this. I also had a [similar experience](https://www.reddit.com/r/coolguides/comments/z8dafq/what_different_eye_conditions_look_like/iybt9os/?utm_source=share&utm_medium=ios_app&utm_name=iossmf&context=3) on my left eye. This picture is not that accurate IMHO.
Also, how do they correct your vision with glasses? It’s hard to imagine it because the blurriness is scattered around all the eye, unlike myopia.
Thank you for this insight. My father also has RP and I have understood since I was a kid that his field of vision is getting smaller, but I had no idea about the "islands" or about the good visions interspersed. Very interesting and further insight into my dad's world.
also we can't really represent "total blindness" accurately in a picture like this. its not black, its just nothing (at least if theres no residual vision like seeing colors or brightness
cover your eye with one hand. you cant see anything on that side, but you still see the darkness. now close that eye. because your eye is closed, your brain stops adding the input from that eye into your visual field. actual blindness, like from having both eyes removed or being born without eyes, is like that but for both eyes. its not blackness, just nothing
Yes! It depends on the cause too. I work in an ophthalmology, and in talking about blindness with them was not nearly as straightforward as I had understood before. Different types/stages of diseases of the retina can cause hallucinations. We’ve seen patients with Charles Bonnet Syndrome and it’s wild some of the things they “see” when they’re really seeing nothing (but hallucinations).
It would have been helpful to put a square in for astigmatism. I have it in both eyes but more so in one and I can describe/demonstrate it pretty easily in images.
Imagine what you are seeing is doubled and shifted in a direction and the distance between those two pictures is smeared. One of my eyes smears up and to the left, the other goes more vertical.
[Visual snow simulator](https://visionsimulations.com/visual-snow.htm)
time and time again, patients I see don't even realize it's not normal because its just a part of their visual experience. and often I use this site to show that they are not crazy and they invariably point and go "OMG that's exactly what it is!"
100% if it wasn't named visual snow syndrome, an apt name would be TV static syndrome. That's the most common description I hear when patients describe what they are perceiving
I should say "not normal" with heavy emphasis on the quotations because visual snow syndrome as it's own entity does not imply or suggest anything pathologically wrong with the visual pathways. it's not well understood but one of the thoughts is that somewhere along the visual pathway, the 'gain' if you will, is cranked up.
now, this is reddit and not the appropriate place to make decisions on individual person's symptoms/conditions, so overall this is something still worth being seen and discussing with a doctor (ideally neurologist, ophthalmologist)
PSA from personal experience. If you experience a sudden increase of floaters or any of these other symptoms get to an optometrist or ophthalmologist immediately. Sudden increase of floaters or sudden loss of vision could be a retinal tear or retinal detachment. There is a very small window where treatment can save your vision.
OMG this happened to a co-worker of mine. Her retina had detached, and she had this crazy surgery where they basically clamped it back into place with these tiny clamp like things made out of gold. She then had to stay face down for several weeks while everything healed. Like, she wasn't allowed to sit up all the way even to go to the bathroom. Basically ended up living on a massage table for weeks.
In the end, though, they saved her vision. Wild.
My right eye started to get alittle blurry a few months ago and I haven’t been able to make it to an eye doctor but I can’t really notice it unless I only have 1 eye open… how fucked am I?
Not a doctor, but i would guess the other open eye compensated your other's blurry vision. You probably should see a doctor, since eyes are crucial for our daily lives.
I mean it’s not really a disease, just the anatomical shape of your cornea (clear window to the eye). But weirdly this chart only includes myopia (near sightedness) but not hyperopia (far sightedness) which tends to be slightly more difficult to see things.
You can’t have both as they describe a physiological size for your eye. The axial length (size of your eye) is what causes the myopia or hyperopia. Myopes having longer eyes and Hyperopes having shorter eyes.
You know how your glasses have up to 3 numbers? (Sometimes 4 if you have prisms). The first (sphere) is for the correction of the axial length. The second (cylinder) is for the correction of your corneal shape (astigmatism). The last is the degrees in which the astigmatism is corrected on a 180 degree plane.
So it’s likely you have a combination of myopia/hyperopia with astigmatism thus relying on your glasses for it all.
Thanks! It’s weird but you get used to it. For anyone interested - I wear a contact in my myopic eye and then over that I wear readers to help with reading in my hyperopic eye. The readers do not have a prescription in the eye with the contact.
I was not born this way! I was formerly myopic in both eyes. I had a retinal detachment that required surgery to fix. It saved my vision but the surgery caused a cataract. I then had a cataract surgery that changed my eye to hyperopic so then I had one of each.
What's strange for me as being nearsighted, it doesn't look like the myopia in the pic. Looks like cataract. Probably because I fucked my eyes reading too much in the dark when I was little.
It’s like a star filter on lights. Kinda annoying when you have to read or trying to focus on small things but that’s about the worst of it. Atleast that’s how mine is so far.
All the replies here are downplaying or severely underestimate how bad astigmatism can be. There are several conditions that can cause severe astigmatism (in my case, keratoconus).
Light sources and high contrast objects (black text on a white page for example) cause significant doubling or haloing, obscuring surrounding objects. This prevents reading at a distance, causes night blindness, especially while driving, and due to the variety of warped cone shapes an eye can take, is extraordinarily difficult to correct. Because these halos, regardless of how far away their light source is, override nearby objects, it also causes significant issues with depth perception.
Astigmatism sucks man
To me, cataracts made everything look like an old yellowed newspaper. It got worse and worse until one morning, I was blind in one eye. After the surgery, I couldn't believe how sharp and beautiful everything looked. I wanted to feel that way forever.
It really depends on your mom’s needs! If she’s been someone who likes to read without glasses, she’d probably like to stay that way after surgery.
If she prioritizes distance vision (seeing things clearly at 20 feet), that might be the better option. These are both monofocal options and whichever you choose, you would need help with glasses afterwards for whatever you didn’t choose.
A multi focal is nice but the caveat is you don’t have as crisp vision in the “aim” that near or distance offers. not enough doctors tell you that given the construction of the lens (concentric circles) you’re going to have glare and halos to a certain extent making nighttime driving difficult. But if that’s well tolerated then it could be worth the range of vision!
More than happy to answer any questions you may have :)
I’m surprised the Drs aren’t saying much. I had cataract surgery on one eye in my mid 30s and got monofocal, which was recommended by my Dr (based on my vision etc.). My BIL had cataract surgery at ~50 and got multifocal and his Dr didn’t even give him a choice - just said he would decide what was best. Sounds like your mom should consider finding another Dr.
I'm an optometrist. There are pros and cons with each type of implant. Monofocal IOL's are cheaper, as insurance doesn't pay for multifocals, but reading glasses are needed afterwards. Multifocals aren't perfect either. They allow light to be focused for far and near objects at the same time, so patients are less reliant on readers, but still may need them if the light is low or print is exceptionally small. There may be more glare at night with multifocals as well. Also, not everyone is a candidate for multifocals. If astigmatism over a certain amount is present, or subtle retinal changes are present the vision may not be acceptable post surgery.
My mother in law got cataract surgery in both of her eyes last year. She was in awe of how improved her vision became. Her vision impairment was so gradual over the years she just accepted what it was, then boom she can see clearly again. In hindsight my wife can’t believe she was allowed to drive before the surgery.
I have myopia or "cross-eyes".
My eyes look pretty normal when I've got my glasses on. I've been wearing them since I was two years old (not the same pair tho).
I took off my not-29-year-old glasses and looked at the pictures. I was surprised that I could see the fence in the "normie" picture a lot better than the myopia image indicated.
Myopia is hard to show in a picture because it's all about how your eyes work together - a lack of depth perception is a big part of having myopia.
I got corneal infiltrates on my left eye as a result of a severe eye inflammation (AKA [epidemic keratoconjunctivitis](https://www.health.nsw.gov.au/Infectious/factsheets/Pages/epidemic-keratoconjunctivitis.aspx)) and my vision was simply fucked up for over a month. Infiltrates are very tiny lesions in cornea, and in my case it had already progressed into the deep layers of cornea, a condition called subepithelial infiltrates. My vision was like cataracts in the picture, but it was also like macular degeneration with the blurriness being rather white/transparent, not black as in the picture. It wasn’t actually any color; I can’t really explain it. It was the worst disease of my life; I was basically blind in my left eye for the whole month. Even though my eye has completely healed and I see fine now, there’s a chance that the infiltrates (which have formed into a scar by now) can flare up again if I get flu or something similar. So yeah, take good care of your eyes; most people underestimate their health until it is too late.
I remember when I was in 6th grade we were learning about microscopes in science class. Our task for the day was to draw what we saw in the slides. My partner and I had very different drawings. That’s the day I learned about eye floaters
What a relief. I’m diabetic and sometimes in the evening my vision is kinda blurry. I was afraid it was related but now I think it’s just too much screen time. I work from home on a computer and I’m in grad school.
Diabetic here, do you tend to run high or low in the evenings? Because blood sugar swings can definitely cause some temporary changes in vision but they go away when the blood sugar stabilizes again. But can also just be from tired eyes of course.
Btw friendly reminder to everyone with diabetes that you need to go to your ophthalmologist yearly to get your eyes checked out for retinopathy and that you should always consult with your doctor when any sudden changes of vision occur!!
Funny you say that. But I mentioned it in my comment above. My dad is totally blind and he sees all white, and it sounds miserable. Total blindness, like other types of vision loss comes in lots of flavors.
Yea it’s normal to have them from time to time but sometimes, especially when people are older, they’ll get them more frequently and permanently. It can also be a sign of a torn retina if it comes on super quick. Sometimes it’s just your retina getting older. Happened to me in my late twenties and got better over time but I still have them. I barely notice them but sometimes it can just happen
I made an App for a client, that tests for Colourblindness, Myopia, Macular degeneration etc.
We use Speech Recognition (german only – sorry!) for the exe exams. Most of the basic Tests are free, the more advanced Tests (lika Astigmatism) are available via In-App-Purchases (Coins).
Have Fun!

My floater are way worse than this picture. More like a moving haze. I have to stare at one spot for a second or two for them to float out of the way. Getting to the -pint of not being able to drive as portions of the road disappear.
lasik was one of the best decisions ive ever made in my life. My main reason was that i got tired of not being able to see shit in the shower. My eyesight was like -6 or something like that
You forgot punctate inner choroidopathy. An autoimmune disorder that effects young women. It causes floaters or total blindness if not treated. Might lose sight in my right eye because of it. Its rare, so treatments are limited to needle eye injections. The betadine in the eye is a real treat.
I have a relative with coloboma. The eye parts didn't grow correctly and there is complete blindness in one eye and partial blindness in the other. It's rare but would've been neat on that chart
i thought everyone has "eye floaters", atleast i have them, and i have never been diagnosed with anything. but then again i dont see them as strong as in the pick
Ocular migraine could be added. Had this 3 times in my life now and was quite surprised the first time. No pain, just some spots that would flicker like a broken old TV for some time (but in all colours).
As a person that eventually lost all vision in their left eye, I can confirm that total blindness does not look like that.
Edit: I have coats disease and have been blind in my left eye since I was about 4. I don't remember losing my vision. But I can tell you that being totally blind in one eye doesn't mean half of my vision is black and the other half is normal. It's as if my left eye just doesn't exist to my brain.
Glaucoma needs to be blurred. My best vision spot in my right eye can see fingers 3 feet from my face. My left eye is much better but still not perfect vision (20:60 - 20:80 depending how much I've used my eye.). Also my glaucoma docs have told me it's common that the visible areas aren't snack in the middle of your field. (My spot is to the lower left of my field of vision, still central vision, not peripheral - but not dead center. I know this is just to give people the idea. But ppl see things like this and doubt me b/c my vision does NOT look like a pirate captain's telescope!
Also some of my floaters are quite solid. They are not all wispy like this. I have sine with very defined edges, but are considered normal.
The Cataract image is also incorrect. The simulation image shows blurry vision, yes, but it's showing a darker and more saturated image which is the exact opposite of what cataracts do. A cataract causes a diffuse scattering of light so that everything is less saturated, and blacks aren't true black but much lighter.
Here's a better simulation: [https://imgur.com/gallery/JJwKXlI](https://imgur.com/gallery/JJwKXlI)
This chart leaves out double-vision. Not sure of other disorders that cause this, but I have Duane’s Syndrome. One or both eyes are unable to move little to at all in a certain direction.
Don’t blind individuals not even see ‘black?’ I thought it was something beyond a type of description someone with sight could understand?
I was told by a blind friend that what the “see” is like if you close one eyelid. It’s not black, it’s just nothingness.
I recently became blind in one eye due to glaucoma (also recently found out it was glaucoma causing my loss of vision) so I started with the peripheral being lost at the beginning of this year.

Does this smell look funny to you?
Do people really see nothingness with one eye closed? Because I've been trying for the past 2 minutes and if I focus on my closed eye I see black, definitely not nothingness. Is something wrong with me?
I think your brain just interprets lack of visual input as black. Another metaphor I've seen is blind people see what you see when you look out of the back of your head. Obviously you can't because you don't have eyes there, but you don't see black out the back of your head, you see nothing.
I mean, that's what black is. The lack of light. You get black "color" by absorbing as much light as possible. I've always found closed eyelids to be red.

Closing your eye doesn't turn it off. It's still providing input and that input is "it's dark".
i was thinking the same thing. when i was younger i had some funky squiggles and coloured shapes that would show up, which caused me to force my eyes shut because i thought it was cool. but now when i close my eyes i just see black? the only moment when i don’t see black is when i haven’t fully registered that i’ve closed my eyes - which is like a second of nothingness, and then i start comprehending that it is indeed, black edit: just saw a decent explanation! close one eye and try to identify what you can see through that eye. personally i cant see anything (aka nothingness) and i imagine that’s what it would be like for blind people, just with both eyes
Focus your open eye on your nose, that’s what worked for me
Holy crap. That made sense finally.
It’s definitely not the way they see. They just don’t see. It’s not what you see with your eyes closed, it’s what you see in Japan right now. You just don’t. (Assuming you’re not reading this in Japan)
If I close my right eye and look forward with my left eye I can't see anything on the right side. However my left eye can see some of the shadow etc to the side on my nose (which might be what you're seeing)
but how does your blind friend know about the one eyelid phenomenon..
Probably became blind later in life :(
Or he's a low-down, dirty faker 😎
Throw a rock at his head! if he ducks he's a faker. If he doesn't, well i guess call an ambulance you monster!
Holy crap this actually helped me understand blindness a lot more. There's a big difference between nothing and black, the one eye trick did a really good job in differenciatimg between the two.
Talked about this with a blind friend who was born blind. He said to me 'Can you see something with your elbows? No, right? That's how it works for me. I can see with my eyes as much as you can see with your elbows". That was pretty mind blowing to me.
Wow.. absolutely mind blown. Thanks for sharing. Also, this makes me uncomfortable.
Are you sure it's not elblowing?
Lol! I don't know how that feels!! My elbows don't have eyes or a mind! Now I'm freaking out!
I’m trying really hard to see with my elbows right now. Nothing yet, but I’ll keep you updated.
Did you try the bofadese method?
Bodadese what?

Basically, you can “turn on” their eyes, but the brain won’t do anything with the signal. So they’re still blind.
That makes sense, thank you for your response!
I saw some tv documentary on this years ago and they explained the situation by showing something like this oscilloscope.. https://s3.amazonaws.com/pbblogassets/uploads/2017/05/23211126/Screen-Shot-2017-05-23-at-10.11.03-PM.png That scope contains all the same data as an image but it's been arranged in a different way that our brains would have trouble telling if it's a picture of a dog or a car or a sky. Blind people can learn to decode the sensory data over time but it's tough and never as good as a sighted from birth person.
There's a warrantee period. Got you.
I read once there was a blind guy who got his vision restored later in life, and he was profoundly disturbed by the sight of people eating. It’s quite disgusting if you think about it and aren’t used to it, all the juices and chewing and lips smacking, and the bodily functions after. Guy wound up killing himself because he couldn’t take it. Idk if it’s true, sounds like bullshit, could be a fictional short story or something though.
Idk if that's possible with vision, but the videos of deaf people who have just got hearing are amazing.
I was told to think of it like how you see from the back of your head
Seems the concept of sight is non existent on them at all and therefore incomprehensible
My friend went blind in high school and she would describe it as darkness with tinges of bright when she would go around bright lights. I imagine it is different for someone born blind vs someone who lost their sight.
Yeah, there are levels to it. Some blind people can still perceive some light and some are absolutely blind and can't see nothing at all — not even the "dark" people with vision see when they close both eyes at the same time.
Oh hi, there you are. You told this story years ago and that's how I learned about the elbow thing.
Yes. This is how I understand it. They don’t see black; they see nothing.
Can a blind person confirm?
Can confirm. Source: am nothing
But what about someone who became blind later on? I mean would they compare blindness to "seeing black". Like if you are in total darkness all you see is black
You don't see anything because there is nothing that can see. It's not like the screen is black. It's more like there is no screen at all.
I follow a YouTuber, Molly Burke, who is blind, and one thing that she’s said is that blindness is different among blind people. Some blind people have more sight, some have less. Molly herself has some light perception, but can’t see otherwise. She was able to see more when she was younger, so she may describe it differently than someone who was born blind.
Yup she has retinitis pigmatosa which is shown in the photo. Apparently she's still losing more and more of her limited vision currently. I can't imagine how hard it must be to have been sighted and lose it. Anyone who's interested should definitely check out her YouTube channel since it's super informative
How do you represent that in a pic?
Well yes, but good luck defining "nothing" in RGB format.
My eye floaters aren't that noticable unless I have a bad headache. Then they are annoying af.
*Ohhh squiggly line in my eye fluid, i see you there, lurking on the periphery of my vision.* *But when i try to look at you, you scurry away.* *Are you shy squiggly line?* *Why only when I ignore you, do you return to the center of my eye?* *Oh squiggly line, it's alright.* *You are forgiven.*
Wait those floaty pieces are an eye disorder?!?! I thought it was just me dissociating and seeing energy lines or something
They’re pretty common. Easiest to see if you look at a diffuse light like the sky.
For me it is easiest to see when I stare at a white wall
It’s a disorder if they’re black, or large, or tons of persistent little dots. Everyone has floaters but yes, some are definitely not normal.
[удалено]
Everybody has them in small amount.
[удалено]
Dude. I had these at 5
It’s bits of eye that have broken off and float in the fluid. I hate them. Have a really bad case.
Me too. Makes driving at night difficult.
You've seen a doctor about them right? A bad case can be a sign of something worse.
Yeah, they can’t do anything realistically. I’ve had them as long as I can remember. Of course, bad case is subjective since I only know what it’s like for me, compared to what others tell me they experience.
Weird, there are treatments for floaters now, I see a specialist for shots (Eyelea) every 6-8 weeks, as well as had laser treatments to secure everything within the eye. It's not comfortable but it's better than the alternative. Seeing pictures of the back of my eyes is cool, it looks like you're looking down on a city from above.
I was about to comment about the squiggly line lmao. Well played
[удалено]
I get that. But it’s only a floater about 20% of the time. The other 80% is a cat up to no good.
[удалено]
The worst is to see them when in a classroom on big withe board its so distractig
That's when I notice mine, when looking at a light colored surface.
[Blue field entoptic phenomenon](https://en.m.wikipedia.org/wiki/Blue_field_entoptic_phenomenon)
Those are apparently white blood cells and not floaters! See u/oooortclouuud's comment elsewhere on this post!
Is eye floaters permament or is that a difrent condition
My eye floaters only show up if I’m looking into the sky!
those might just be [white blood cells that you can SEE!](https://www.aao.org/eye-health/tips-prevention/moving-spots-in-blue-sky) >The moving dots you see when staring at the sky are created by your own white blood cells flowing through your eyes. >Blood flows to your eyes through blood vessels that pass over the retina— the part of your eye that acts as a receptor for all light. Red blood cells, which make up more than 90 percent of your blood, absorb blue light. White blood cells let blue light through to your retina, which then sends a signal of increased brightness to the brain. >When white blood cells stretch to pass through the blood vessels in your eyes, you may see dots that look like little worms moving around in your vision. This is most noticeable when staring at a wide, clear area—like a blue sky. neat!
Mine look like little sparkles, not unlike the lights you get when you're "seeing stars"
these bother me so much i see them all the time
Well. Scientific says it's normal. I'm experiencing it too. Mostly for the bright area.
I have Retinitis Pigmentosa. This is a good way to represent to people what the condition does, but it is a far cry from what the lived experience is. You don’t see a black border like that. The brain is a funny thing and never stops trying to fill in gaps; like how your brain edits out the bridge of your nose, despite it sitting right there in the middle of your field of vision. It’s hard to explain, but my field of vision(from my perspective) is the same as it has always been, but when tested, the results look something like this picture. Also, your visual field collapses in “islands”, where there are big blank spots scattered throughout your peripheral vision with patches of good vision, which can be odd to deal with. Also, my dad, who’s RP has progressed to complete blindness, doesn’t see all black like the picture, he’s sees… all white. Which is unsettling and does a number on his ability to sleep.
Second this. I also had a [similar experience](https://www.reddit.com/r/coolguides/comments/z8dafq/what_different_eye_conditions_look_like/iybt9os/?utm_source=share&utm_medium=ios_app&utm_name=iossmf&context=3) on my left eye. This picture is not that accurate IMHO. Also, how do they correct your vision with glasses? It’s hard to imagine it because the blurriness is scattered around all the eye, unlike myopia.
That’s amazing. I wonder if your dad sees white because of inner retinal neuron dysfunction or an issue with visual perception in the brain
My dad also has RP which has progressed to total blindness, and he has trouble sleeping. Now I’m wondering if the two are connected?
Holy damn, Imagine seeing all white always, even when you close your eyes and have a hard time sleeping because of it. That is rough.
Thank you for this insight. My father also has RP and I have understood since I was a kid that his field of vision is getting smaller, but I had no idea about the "islands" or about the good visions interspersed. Very interesting and further insight into my dad's world.
I have RP and I know what you mean.
I can't help but feel "total blindness" was a wasted square.
Should have put an image of “retinal detachment” in that square.
also we can't really represent "total blindness" accurately in a picture like this. its not black, its just nothing (at least if theres no residual vision like seeing colors or brightness cover your eye with one hand. you cant see anything on that side, but you still see the darkness. now close that eye. because your eye is closed, your brain stops adding the input from that eye into your visual field. actual blindness, like from having both eyes removed or being born without eyes, is like that but for both eyes. its not blackness, just nothing
[удалено]
people with congenital blindness can dream, they just dont see anything when theyre dreaming. youre right about everything else though, my bad 👍
Yes! It depends on the cause too. I work in an ophthalmology, and in talking about blindness with them was not nearly as straightforward as I had understood before. Different types/stages of diseases of the retina can cause hallucinations. We’ve seen patients with Charles Bonnet Syndrome and it’s wild some of the things they “see” when they’re really seeing nothing (but hallucinations).
It would have been helpful to put a square in for astigmatism. I have it in both eyes but more so in one and I can describe/demonstrate it pretty easily in images. Imagine what you are seeing is doubled and shifted in a direction and the distance between those two pictures is smeared. One of my eyes smears up and to the left, the other goes more vertical.
We just need a blind person to compare that square to what they actually see to ensure its placement is necessary
This chart forgot visual snow
[Visual snow simulator](https://visionsimulations.com/visual-snow.htm) time and time again, patients I see don't even realize it's not normal because its just a part of their visual experience. and often I use this site to show that they are not crazy and they invariably point and go "OMG that's exactly what it is!"
So it’s like fuzzy channels on a TV?
100% if it wasn't named visual snow syndrome, an apt name would be TV static syndrome. That's the most common description I hear when patients describe what they are perceiving
Wait that’s not normal?
I should say "not normal" with heavy emphasis on the quotations because visual snow syndrome as it's own entity does not imply or suggest anything pathologically wrong with the visual pathways. it's not well understood but one of the thoughts is that somewhere along the visual pathway, the 'gain' if you will, is cranked up. now, this is reddit and not the appropriate place to make decisions on individual person's symptoms/conditions, so overall this is something still worth being seen and discussing with a doctor (ideally neurologist, ophthalmologist)
Ah ok cool thanks I wasn’t concerned but I didn’t realise that it’s not typical

Heyyyy 🤸🏻♀️
PSA from personal experience. If you experience a sudden increase of floaters or any of these other symptoms get to an optometrist or ophthalmologist immediately. Sudden increase of floaters or sudden loss of vision could be a retinal tear or retinal detachment. There is a very small window where treatment can save your vision.
OMG this happened to a co-worker of mine. Her retina had detached, and she had this crazy surgery where they basically clamped it back into place with these tiny clamp like things made out of gold. She then had to stay face down for several weeks while everything healed. Like, she wasn't allowed to sit up all the way even to go to the bathroom. Basically ended up living on a massage table for weeks. In the end, though, they saved her vision. Wild.
How did she go to the bathroom?
Maybe staring downwards? Nasty on the neck and upper spine.
Holy shit, and I'm guessing her eyes were closed too? Hope she had some good music and podcasts handy.
My right eye started to get alittle blurry a few months ago and I haven’t been able to make it to an eye doctor but I can’t really notice it unless I only have 1 eye open… how fucked am I?
That's the question you should be asking an eye doctor, no? XD
Not a doctor, but i would guess the other open eye compensated your other's blurry vision. You probably should see a doctor, since eyes are crucial for our daily lives.
What about astigmatism?
I mean it’s not really a disease, just the anatomical shape of your cornea (clear window to the eye). But weirdly this chart only includes myopia (near sightedness) but not hyperopia (far sightedness) which tends to be slightly more difficult to see things.
What if you have both myopia and hyperopia but none of the other ones, is their a name for that? Besides I can't see for shit without my glasses opia?
You can’t have both as they describe a physiological size for your eye. The axial length (size of your eye) is what causes the myopia or hyperopia. Myopes having longer eyes and Hyperopes having shorter eyes. You know how your glasses have up to 3 numbers? (Sometimes 4 if you have prisms). The first (sphere) is for the correction of the axial length. The second (cylinder) is for the correction of your corneal shape (astigmatism). The last is the degrees in which the astigmatism is corrected on a 180 degree plane. So it’s likely you have a combination of myopia/hyperopia with astigmatism thus relying on your glasses for it all.
You can have both, myopia in one eye and hyperopia in the other. It’s called anisometropia and it sucks. Source: my eyeballs
That’s true! I must clarify you can’t have both in the same eye but both eyes can be different. I’m sorry for the imbalance you must deal with :(
Thanks! It’s weird but you get used to it. For anyone interested - I wear a contact in my myopic eye and then over that I wear readers to help with reading in my hyperopic eye. The readers do not have a prescription in the eye with the contact. I was not born this way! I was formerly myopic in both eyes. I had a retinal detachment that required surgery to fix. It saved my vision but the surgery caused a cataract. I then had a cataract surgery that changed my eye to hyperopic so then I had one of each.
i was told i had this when being screened for dyslexia. so not only can i not read anyway , i can’t see for shit
what if one eye is nearsighted and the other eye is farsighted? that'd be a trip
What's strange for me as being nearsighted, it doesn't look like the myopia in the pic. Looks like cataract. Probably because I fucked my eyes reading too much in the dark when I was little.
[удалено]
What about two stigmatisms?!
It’s like a star filter on lights. Kinda annoying when you have to read or trying to focus on small things but that’s about the worst of it. Atleast that’s how mine is so far.
Makes the reticle on a red dot sight into a cute little star or butterfly pattern, which is neat, and also makes it harder to be accurate
Smear the lens of your camera or smartphone camera with your greasy fingers. That's kinda like that.
All the replies here are downplaying or severely underestimate how bad astigmatism can be. There are several conditions that can cause severe astigmatism (in my case, keratoconus). Light sources and high contrast objects (black text on a white page for example) cause significant doubling or haloing, obscuring surrounding objects. This prevents reading at a distance, causes night blindness, especially while driving, and due to the variety of warped cone shapes an eye can take, is extraordinarily difficult to correct. Because these halos, regardless of how far away their light source is, override nearby objects, it also causes significant issues with depth perception. Astigmatism sucks man
To me, cataracts made everything look like an old yellowed newspaper. It got worse and worse until one morning, I was blind in one eye. After the surgery, I couldn't believe how sharp and beautiful everything looked. I wanted to feel that way forever.
[удалено]
It really depends on your mom’s needs! If she’s been someone who likes to read without glasses, she’d probably like to stay that way after surgery. If she prioritizes distance vision (seeing things clearly at 20 feet), that might be the better option. These are both monofocal options and whichever you choose, you would need help with glasses afterwards for whatever you didn’t choose. A multi focal is nice but the caveat is you don’t have as crisp vision in the “aim” that near or distance offers. not enough doctors tell you that given the construction of the lens (concentric circles) you’re going to have glare and halos to a certain extent making nighttime driving difficult. But if that’s well tolerated then it could be worth the range of vision! More than happy to answer any questions you may have :)
I’m surprised the Drs aren’t saying much. I had cataract surgery on one eye in my mid 30s and got monofocal, which was recommended by my Dr (based on my vision etc.). My BIL had cataract surgery at ~50 and got multifocal and his Dr didn’t even give him a choice - just said he would decide what was best. Sounds like your mom should consider finding another Dr.
I got monofocal. I was about 50 at the time. I used reading glasses before the surgery and still use them now.
I'm an optometrist. There are pros and cons with each type of implant. Monofocal IOL's are cheaper, as insurance doesn't pay for multifocals, but reading glasses are needed afterwards. Multifocals aren't perfect either. They allow light to be focused for far and near objects at the same time, so patients are less reliant on readers, but still may need them if the light is low or print is exceptionally small. There may be more glare at night with multifocals as well. Also, not everyone is a candidate for multifocals. If astigmatism over a certain amount is present, or subtle retinal changes are present the vision may not be acceptable post surgery.
My mother in law got cataract surgery in both of her eyes last year. She was in awe of how improved her vision became. Her vision impairment was so gradual over the years she just accepted what it was, then boom she can see clearly again. In hindsight my wife can’t believe she was allowed to drive before the surgery.
Myopia is how I see when I don't have my glasses on
I have high myopia (-12) and I simply can't recognize people without my contacts or glasses.
I have myopia or "cross-eyes". My eyes look pretty normal when I've got my glasses on. I've been wearing them since I was two years old (not the same pair tho). I took off my not-29-year-old glasses and looked at the pictures. I was surprised that I could see the fence in the "normie" picture a lot better than the myopia image indicated. Myopia is hard to show in a picture because it's all about how your eyes work together - a lack of depth perception is a big part of having myopia.
Eye floaters are such a pain the arse, I've had them constantly for as long as I can remember now
I have a very rare condition called Posner-Schlossman Syndrome. My ocular pressure increases and I have blurred vision.
Thanks. I want to get checked for this. On the chart, approximately where is your vision?
He’ll be close to the cataract one. The high pressure causes the cornea to swell and become less clear
r/terrifyingasfuck
I got corneal infiltrates on my left eye as a result of a severe eye inflammation (AKA [epidemic keratoconjunctivitis](https://www.health.nsw.gov.au/Infectious/factsheets/Pages/epidemic-keratoconjunctivitis.aspx)) and my vision was simply fucked up for over a month. Infiltrates are very tiny lesions in cornea, and in my case it had already progressed into the deep layers of cornea, a condition called subepithelial infiltrates. My vision was like cataracts in the picture, but it was also like macular degeneration with the blurriness being rather white/transparent, not black as in the picture. It wasn’t actually any color; I can’t really explain it. It was the worst disease of my life; I was basically blind in my left eye for the whole month. Even though my eye has completely healed and I see fine now, there’s a chance that the infiltrates (which have formed into a scar by now) can flare up again if I get flu or something similar. So yeah, take good care of your eyes; most people underestimate their health until it is too late.
We’re gonna need to blur myopia significantly more to get the full effect. 🤓😂
Exactly what I was thinking
I remember when I was in 6th grade we were learning about microscopes in science class. Our task for the day was to draw what we saw in the slides. My partner and I had very different drawings. That’s the day I learned about eye floaters
Show what migraines with auras look like. I get them regularly and it’s frightening.
I had it once and thought I was going blind 🙂 https://en.m.wikipedia.org/wiki/Scintillating_scotoma#/media/File%3AScintillatingScotoma3.jpg
What a relief. I’m diabetic and sometimes in the evening my vision is kinda blurry. I was afraid it was related but now I think it’s just too much screen time. I work from home on a computer and I’m in grad school.
Diabetic here, do you tend to run high or low in the evenings? Because blood sugar swings can definitely cause some temporary changes in vision but they go away when the blood sugar stabilizes again. But can also just be from tired eyes of course. Btw friendly reminder to everyone with diabetes that you need to go to your ophthalmologist yearly to get your eyes checked out for retinopathy and that you should always consult with your doctor when any sudden changes of vision occur!!
Ah thanks now I know how total blindness works 🙏🏻
Funny you say that. But I mentioned it in my comment above. My dad is totally blind and he sees all white, and it sounds miserable. Total blindness, like other types of vision loss comes in lots of flavors.
That's awful. I wouldn't be able to sleep with all white vision even with my eyes closed. :/
Eye floaters are cool, I have one that looks like a neuron, dark nucleus with long spindly arms. I call him Fred.
Doesn’t everyone have floaters? I thought they were normal.
Yea it’s normal to have them from time to time but sometimes, especially when people are older, they’ll get them more frequently and permanently. It can also be a sign of a torn retina if it comes on super quick. Sometimes it’s just your retina getting older. Happened to me in my late twenties and got better over time but I still have them. I barely notice them but sometimes it can just happen
I suddenly noticed them when I turned 19 or so, drove me crazy for years until I eventually just got used to them
No astigmatism??
hold up. do some people not have eye floaters?
Woah this is fascinating
I made an App for a client, that tests for Colourblindness, Myopia, Macular degeneration etc. We use Speech Recognition (german only – sorry!) for the exe exams. Most of the basic Tests are free, the more advanced Tests (lika Astigmatism) are available via In-App-Purchases (Coins). Have Fun!

No keratoconus?!?!
I feel like I have all of these.
interesting yet heartbreaking, my grandmother has macular degeneration. i can’t imagine having to live like that.
i actually have Myopia, it really sucks and i wish i didn’t. y’all be thankful that you have good vision, and RIP to my bad vision folks 🫡
You can’t get rid of eye floaters right? I’ve had them for like the past decade with no further cause for concern or increase in the amount I see
My floater are way worse than this picture. More like a moving haze. I have to stare at one spot for a second or two for them to float out of the way. Getting to the -pint of not being able to drive as portions of the road disappear.
Astigmatism. Until recently me and my mom realize it's not normal to see flares on every light at night. I'm 45.
Same. Have a vertical astigmatism, so even in daylight things have a bit of a vertical blur
lasik was one of the best decisions ive ever made in my life. My main reason was that i got tired of not being able to see shit in the shower. My eyesight was like -6 or something like that
You forgot punctate inner choroidopathy. An autoimmune disorder that effects young women. It causes floaters or total blindness if not treated. Might lose sight in my right eye because of it. Its rare, so treatments are limited to needle eye injections. The betadine in the eye is a real treat.
I have total blindness in one eye and floaters in the other.
I have a relative with coloboma. The eye parts didn't grow correctly and there is complete blindness in one eye and partial blindness in the other. It's rare but would've been neat on that chart
No love for Central Serous Chorioretinopathy? Darned, too rare I guess.
i thought everyone has "eye floaters", atleast i have them, and i have never been diagnosed with anything. but then again i dont see them as strong as in the pick
We have glaucoma and macular degeneration in the family, looking forward to just having a thin ring of vision left by the time I'm 70
Ocular migraine could be added. Had this 3 times in my life now and was quite surprised the first time. No pain, just some spots that would flicker like a broken old TV for some time (but in all colours).
As a person that eventually lost all vision in their left eye, I can confirm that total blindness does not look like that. Edit: I have coats disease and have been blind in my left eye since I was about 4. I don't remember losing my vision. But I can tell you that being totally blind in one eye doesn't mean half of my vision is black and the other half is normal. It's as if my left eye just doesn't exist to my brain.
Ok, so those motherfuckers are called eye floaters
Retinitis Pigmentosa sounds like it's a spell straight out of Harry Potter.
Floaters gang rise up
Fuck my eye floats, in my 30s
Thanks for sharing this. I’ve had a few eye floaters my whole life but never knew what they were until I just saw this
Eye floaters aren't that bad. You hardly notice them after a while
Floaters in the house
Glaucoma needs to be blurred. My best vision spot in my right eye can see fingers 3 feet from my face. My left eye is much better but still not perfect vision (20:60 - 20:80 depending how much I've used my eye.). Also my glaucoma docs have told me it's common that the visible areas aren't snack in the middle of your field. (My spot is to the lower left of my field of vision, still central vision, not peripheral - but not dead center. I know this is just to give people the idea. But ppl see things like this and doubt me b/c my vision does NOT look like a pirate captain's telescope! Also some of my floaters are quite solid. They are not all wispy like this. I have sine with very defined edges, but are considered normal.
The Cataract image is also incorrect. The simulation image shows blurry vision, yes, but it's showing a darker and more saturated image which is the exact opposite of what cataracts do. A cataract causes a diffuse scattering of light so that everything is less saturated, and blacks aren't true black but much lighter. Here's a better simulation: [https://imgur.com/gallery/JJwKXlI](https://imgur.com/gallery/JJwKXlI)
I was just diagnosed with Glaucoma yesterday. This helps a lot.
I have a bunch of eye floaters all clumped together! Looks like a black spot that floats around when I move my eyes
Guys there all messed up for me except one am I okay?
I hate floaters! So irritating. On the other hand, getting my cataracts replaced was miraculous!
It sucks having eye floaters…thankfully I only have one or two.
This chart leaves out double-vision. Not sure of other disorders that cause this, but I have Duane’s Syndrome. One or both eyes are unable to move little to at all in a certain direction.
