I wonder how this would work for people with the inability to visualize objects in their mind
not blind spots or blindness, but i have aphantasia and when i wear an eyepatch to help with hemiplegic migraines, my brain still fills in that ""peripheral vision" on that side. its really disorienting sometimes because it wont include things like my arm, but will be known static patterns my brain recognizes like my porch, my desk... hope this helps!
I got costume finger extensions and after wearing them for a few hours a day multiple days in a row my brain started "accepting" them as part of me, and it would cause migraines trying to feel things with them and i would feel disoriented when id take them off.
Brains be dumb
You know, this is totally cringe internet self treatment behavior on my part, but it's cheap and easy to see if an eyepatch will help with my hemiplegic migraines so thanks for the idea. And as far as I know it's not super dangerous unless I'm driving.
If you know someone you can try that.
Personally I don’t think this would affect them because the effect described isn’t something that only happens to people that lose sight. It’s in general how our brain processes images. Our retina is inside of the eye, so it needs to have a connection to outside of the eye. Everyone has a blind spot where the retina leaves the eye. Our brains just add in information from around that. There are blind spot test images you can google. You cover one eye and look at the left of 2 objects in the image on a plain background. At a certain distance the right object will vanish and replaced by the Color of the background. So a person that lacks visual thinking would walk around with 2 black spots at all times if it wasn’t working for them. Also you can see your nose at all times. Your brain just edits it out because it’s not helpful.
My personal guess is that our ability to see is a lot more important than the visual thinking in terms of evolution. You can’t survive in Stone Age worlds without proper vision but not having developed visual thinking is not required.
Also you can see your nose at all times.
Is this the new "You are now breathing manually"?
They still have a blind spot- so yes it would still happen. Everyone with normal eyesight already has a small spot where their brain makes up the image. There are some.. tests? that can prove it to you
I'm unable to visualize objects in my mind but this optical illusion worked for me -- my brain filled in missing information (and not so well at all).
Personally I feel it stops me from intentionally visualising things, but if my brain wants to make things up (blindspot/dreaming) I can still see things.
Well all humans have a blind spot in their vision. In your right eye, it's somewhere to the right of the center of your vision. I have aphantasia and frankly nothing about the blind spot seems different than the description given by normal people. I don't normally see the blind spot and my brain fills it in just fine. I do have it, however. I would have never realized we had that spot had I not read a post that taught you how to check it.
If you don't know, imagine two dots placed horizontally from one another. Close your left eye, look at the left dot and move back and forth. At a certain point, the right dot will disappear from your vision. That's your blind spot

Yeah, I was also wondering about the accuracy. My mum has macular degeneration, worse in one eye than the other. Her worse eye gives her a zigzag view of the world which her brain has learned to cope with better over time, but it's still nothing like what's suggested in this video.
Our brains aren’t exactly hard coded. In computer terms when we are born we only have a bios installed but all our hardware has no clue what it is doing or supposed to do. Our brains simply learn patterns in the information organs send it and eventually it can draw useful information from it. It can even swap the image our eyes send just because the world is less confusing that way. All this means that every eye illness and even the pattern itself will cause different coping mechanisms by the brain to make the best out of it.
Basically, we make our own drivers
Yes exactly! That’s also the basic idea behind stuff like neuralink(just talking about the concept here, no clue if musk is actually making progress here and I frankly don’t care). Because our brains work like that we can in theory add things to our neural network and our brain can potentially learn to use that device. Retina implants work like that already. If your nerve is still intact you can get a camera hooked up to your optic nerve and your brain will eventually use its data to see again on that eye. Cochlea implants work in the same way. For all of them we need a working nerve tho. So in computer slang we currently don’t have enough pcie lanes to attach more devices into our system. That’s why most of that stuff needs a chip directly in the brain. If we give that enough time stuff like cyberpunk isn’t even crazy anymore.
Especially with smartphones, smartwatches and ar technology is getting closer to our bodies as time goes on. And there have already been ideas for smart contact lenses. Which would be quiet annoying in a lot of ways but the idea has appeal.
Yeah, I knew this video was BS immediatly when I saw how it showed macular degeneration which my grandma suffers, I know it varies between individuals which was explained to her and my mother and aunts who have been with my grandma to the ophthalmologist (since she can't drive anymore) and retold things. In the case of my grandma, her vision is parted, disaligned, she can read text but only in specific positions where she can see it together, while in others she sees it incomplete or parted or deformed; she can still see faces and her case isn't too bad but she has described how it's weird how the faces of people warp. You can see her read menus in restaurants but she tilts it and moves it around to read along, will sometimes ask to be sure she is reading something right.
My grandma has also adjusted to this over time and is still very independent, living alone, and her cooking has not suffered one bit as she remembers the recipes and can still manage to read the labels.
So it’s like the Photoshop “context-aware fill” tool?

This is also the reason for the effect where you quickly glance at a clock and it seems like the second hand repeats itself or goes backwards a second, it's because your brain guessed wrong
And because my other eye probably sees it?!
Sometimes, but not always. Give it a Google, you can easily make a black dot on a white page "disappear" entirely, because your brain just fills your blind spot with "more white page"
What you are describing is called Charles Bonnet syndrome. It is common but by no means guaranteed in patients with significant vision loss; I wouldnt call this video inaccurate at all. Many many patients with these conditions just experience scotomas (ie dark or gray spots).
in AMD patients don't generally experience the scotoma per se. they often report blurriness, but usually it turns out that they are describing the degraded margins of the scotoma. the interior kind of vanishes from experience - it's rarely described as having any qualities at all, much less darkness - though it can reappear under some conditions, and it sometimes is involved in hallucinations. but usually there's just... nothing there.
this is a good paper that details the situation: https://pubmed.ncbi.nlm.nih.gov/22863789/
with glaucoma, too, it's often a problem with patients that they don't notice how much they've lost. it's not like tunnel vision (as it is with RP patients, who are very aware) as illustrated here, more like a very very gradual reduction in contrast..
sudden vision loss, though, like a retinal detachment, does certainly appear like "a curtain falling over the eyes".
Using acronyms doesn’t help people understand what you are talking about.
You lost me at the second “word” of your post
Maybe I can help relieve your understandable frustration with unexplained acronyms.
AMD means Age Related Macular Degeneration, and RP means Retinitis Pigmentosa.
Dude. Thanks for sharing . I had no idea .
Agreed. With 5°ish of vision left due to RP, I don’t see black; it’s that my entire visual field is just what I can see. There’s no way to tell what’s actually missing.
Ah thank you …after reading your comment; finally it makes sense (no diss), I’m watching this video and it just didn’t add up with what I’ve been described.
Just wanna add that people who lost 100% of their vision due to an accident don't see black at all. My friend lost his sight (both eyeballs removed) and he describes what he see as nothingess. Like the AV cable is unplugged or something. He's seen the color black for 30 years before the accident and that's not what he sees. He sees something that is impossible to explain.
This is called Charles Bonnet Syndrome and is incredibly interesting. I’ve worked in ophthalmology for many years. Many patients were unaware of this syndrome and did not mention what they saw (often as strange as small people dressed in costume) for fear of their mental health being judged. The utter relief these patients expressed once this syndrome was explained was amazing.

My aunt would see piles of stones in her path (macular dystrophy). It was very annoying. Eventually she went almost profoundly blind, and it stopped.
Man, it's so frustrating when a viral video with misinformation is gaining traction. I've been on a crusade to stop people from buying colorblind glasses, because viral marketing of their scam is keeping them in business. Everyone wants to see people crying when they see "color for the first time"
But you're able to see this post and type?
The clown typed that /s
They need to make glasses with clowns on them.
It's still much better than believing that blind people only see the darkness, right?
Should probably be titled "how blind people's eyes work" with some additional info like yours to supplement that.
The amount of time I take looking around a room when someone calls my name is crazy. Everything looks normal until I look exactly at the person then the scenery changes.
So I have a blind spot and for me it’s more like nothing is there. Like when I look at the board at the eye doctor the spot where one of the letters is just gets all blurry like using old photoshop blend tool. It kinda grabs the parts of the blind spot from around it and fills it in. Luckily it’s at like the top left part of my vision and not directly in the center.
Hello fellow person with Charles Bonnet syndrome!
i have a little crack in my VR headset which results in a little black area like in one of his glasses and i literally can't see it ( or rather process it ) anymore 1h+ into wearing the headset
What you are describing as far as the hallucinations is Charles Bonnet Syndrome.
I once was paid $80 USD to do a survey regarding this syndrome as I am also legally blind.
I mostly get kind of super slow motion fireworks inside of a hole of nothingness. But for me nothingness is like grey not black.
Yeah as someone who is near legally blind in their left eye (but wasn’t always) that’s exactly what happens. I constantly think I’m seeing shit in the periphery on my left side only to look and see nothing there or nothing close to what I thought it was. It’s actually the reason I don’t have a drivers license because I constantly get the impression there’s a car to my left and it makes me super anxious and so I can’t pay attention to the road.
Agree on the "your brain makes shit up" element. Legible, no. Sparkly and weird, yes (also hallucinations too)
your brain MAKES SHIT UP for the black areas in this video with what it reckons should be there
THIS.
Here's proof that you're right: The human eye sees upside down. Your brain flips the image, because your brain has learned enough to know that it's wrong. Experiments have been done with participants wearing upside-down glasses, and their brains stopped flipping the image (meaning, with glasses that flipped the image, their brains learned they were seeing "correctly," so their brains didn't flip the image to correct it). And when they took the upside-down glasses off, they saw the world upside down until their brains figured it out and corrected it (by flipping the image again).
Your brain does all kinds of things like this subconsciously, all the time.
Here's an easy experiment you can do to notice something your brain does, subconsciously, which is actually amazing: Go to the movies... but before you do, set an alarm in your phone to go off when the movie ends.
When you first walk into the theater, notice how strong the popcorn smell is. It's almost overwhelming, right? Try to notice the smell when the alarm goes off. It's barely there... except, it's actually just as strong as before, but your brain realized the smell isn't harmful, so your brain tries to factor out the popcorn smell, to pay attention in case any harmful smells are in the air. It's a self defense mechanism usually referred to as Olfactory Fatigue.
As if the visuals weren’t terrifying enough…, thanks for the new unlocked fear mate!
I've lost the left side peripheral vision in my left eye due to surgery, and it's just like you say. I don't see black I see what my brain thinks is there. As I sit here now I can 'see' the bookshelves to my left.
It's most disconcerting in supermarkets, it's like a heist movie where the bad guys have hung a photo in front of a surveillance camera. I'm there just checking out the cheese section, with no one to my left, then someone appears suddenly out of nowhere, far too close, all the while my brain had been showing me an empty aisle to my left.
This is such a perfect set up for a good horror story. What if all those things your brain is “making up” are actually there! You just can’t touch them… you know, yet.
Yeh, as a blind person this always drives me nuts.
Everyone has two blind spots where the optic nerve is. But if I drew two black circles and said 'this is how normal vision looks' you'd all think that was crazy.
I have a shit-ton of those, but I cannot see them. Now it is getting much worse and my peripheral vision is screwed, I do get what Id call a general feeling of oppression in my visual field. Almost like visualised doom. But my brain does its best to make up for it, and at its worst this has included walking in front of a double decker bus having just one step before been "certain' that the road was clear.
So then are completely blind people tripping balls all the time?
I've got fucked up optical nerves, which affects a small area in the center or my sight. The worst part about having your brain make shit up is that it becomes super tough to actually figure out where objects starts and ends.
Well, this post gave me anxiety and your comment gave me some more.
Even those with healthy eyes can see how this "brain filling in" effect works. In a very small scale.
We all have a blindspot in our vision, off to the outer side of each eye. This is because the ocular nerve leaves the eye slightly on the inner side of each eye, and there's no sensory cells in this spot.
The brain uses the other eye to compensate for this spot usually, but if that's not available it just fills in the "background" as you said, so you don't see a literal black spot.
https://www.scientificamerican.com/article/find-your-blind-spot/
Im not sure if Im shocked or scared
I actually searched before posting to see if this might be a repost. I didn’t find it so posted.
Some people do see black holes.
1/6 of my right eye has a blind spot and I literally see nothing but black black there, and I did not get it until my teenage years.
So your post is highly innacurate. Sure, thanks for the extra information but don't state that other people's life experiences are false without actually knowing for sure.

What about the illegal blind
Believe it or not, jail.
Do not pass go.
Late for a dentist appointment? Jail
We have the best patients in the world....because of jail
I don't know what this world is coming to, see that guy over there, we arrested him for mopery
With intent to creep.
From the Legally Blonde universe and the minds of Legally Blonde and Legally Blonde 2, comes the brand new 2024 summer hit
Illegally Blind!
*Starring a corporeal voice
Becoming blind die to greed
I think whats important is that there are way way more legally blind folks than those with truly no light perception in either eye. So the average “blind person” may have some bits of vision as depicted in this video.
I find this tremendously useful for public education, as everyone seems to assume a person claiming to be blind have no light perception, then notice they might be able to read very large print as if its a “gotcha”. They are still extemely limited even if they have some vision remaining.
Understanding what it's like to be "legally blind" also helps make some other things make sense.
I remember seeing a video some years back (can't remember who made it or where I saw it) where they were talking to a guy who was blind, he could see a very, very small space of light, and what he could see was blurred beyond recognition. Basically, he couldn't make out any shapes. Even large print type, wouldn't be able to read it. But he could see that a color was present in his very limited scope of vision.
And he said that was why color-coding those crosswalk entrances and exits was so important. He'd met people who understood why there were bumps, so someone could feel when they were on one, but couldn't understand why they couldn't be the same color as the sidewalk. In fact, in some places, they were. But it's really, really helpful to have more information. Crossing a busy street is nerve-wracking enough. Add in being nearly totally blind. Knowing what color the, "Cross the road here," part of the sidewalk is going to be really helps. And there are a lot of other small accessibility features like that a lot of people see and don't understand the purpose of.
My blindness/legal blindness is huge black puddles and the parts not like that are like Vaseline in most of my eyes but for one very small circle of vision in left eye. I can make stuff out, kind of, like read a text if I hold phone up to left eye at a specific angle.
People on the bus have tried to shame me as a faker. They have trouble with anyone in dark glasses using a white cane who sees even the tiniest sliver of anything beyond pitch black.
It gets annoying for sure.
You are just saying the same thing over and over. Hey, did you know that not all blind people are completely blind???
I think the point is, though, that one can be legally blind and not be fully blind. Not all blind people have completely dark vision. They can have some vision, and not be fully blind.
Exactly. Blind is blind, there are many ways people can be impared.

Also, those numbers are with best possible correction. So there isn't actually any "without my glasses I'm legally blind".
So are they blind?
Yes, they meet the legal definition of blindness, which is 6/60 in Australia because we use the metric system, but in the US that would convert to 20/200 (as opposed to 20/20 which is average vision).
Although they can also be legally blind if their visual acuity is 10/20 but their peripheral vision has decreased to less than 10 degrees of vision. Our standard peripheral field is 120 degrees, but someone whose field of view has decreased so much that they have less than 10 degrees of their field remaining, they obviously would also have an incredibly difficult hard time living life normally when there are so many hazards and objects they cannot see at all in their field of vision. So these people are also classified as legally blind.
How accurate is this?
As someone who is legally blind I watched this video multiple times and have no idea how accurate it is
As someone who is illegally blind I didn't have time to watch the video. The cops are closing in on me and it's hard to run because I keep running into the wall.
Ask me again in 40 more cake days

Optometrist here. They're not perfect but certainly fairly reasonable depictions. The most accurate are definitely the cataract (the one in this video depicts a very advanced cataract) and the glaucoma ones.
I am legally blind with a condition similar to macular degeneration.
It's central vision loss which is the main issue. All of your ability to see very fine details happens within a very small area in the center of your vision, around 10 degrees or so. This is the reason your eyes have to track left to right while reading, try staring at one word in a book and try to read another word a few lines away without moving your eyes.
Losing that central part of your vision has a massive impact on your ability to see fine details but really doesn't affect your ability to say see stairs coming up or notice a person walking towards you. It will affect your ability to read the billboard posted next to the stairs or notice if the person who is walking towards you is looking at you or not.
I have to get pretty close to a person to read their face, like within a couple feet. But witihin that distance I still can perceive their face pretty much normally. I'm writing this with my face 8 inches from a 32 inch monitor and am still using windows zoom feature at large degree. This "O" is about the size of my pinky nail for reference.
The diabetic one isnt very accurate. Those dark spots are there but they are small and float around, they are easy to confuse as eye floaters. That's basically what they are. Only there are alot of them. They are small and easy to ignore unless your looking at bright surfaces. They don't stay in one spot. It's basically like eye floaters that get more numerous instead of growing that large. I have hundreds of them but they aren't that apparent unless I'm looking at a blue sky or something. They might get that large but it'll still be non stationary and there will be more rather than bigger.
Dark spots for diabetic retinopathy would be accurate in the case of diabetic macular edema, which is not what you are describing. You are referring to vitreous hemorrhage, which is a different subtype of diabetic retinopathy.
Time for some Avastin!
Diabetic retinopathy is highly variable. Many patients dont get many small floaters like you describe, but rather large bulky ones; it tends to depend on the nature if their bleeding and consistency of their vitreous gel inside their eye. Some get total blackout with their floaters because their hemorrhages are so severe.
In any case whats depicted in the video may be supposed to simulate macular edema which is stationary blurry spots in your vision.
happy cake day
My roommate is blind and from what she described me her vision looks like, this isn‘t accurate at all.
Fairly accurate. Also have to understand that each individual is different even if they have the same eye condition/vision impairment.
I work for a Low Vision device company. It’s pretty incredible stuff and I’ve had plenty of tear jerker moments working with visually impaired people.
Thanks for the pitch black example. We had no clue what that looked like lol.
Do truly blind people even see black or absolute nothing? wtf would complete nothing look like?🤯
People born blind see nothing.
Actually, you can see nothing, too. If you close both of your eyes, you see the inside of your eyelid. If you close one of your eyes, the eye that's closed sees nothing.
no i can distinctly focus on the closed eye and i see black/inside of my eyelid
Fine. What you can see out of the back of your head is what blind from birth people see.
🤯🤯
Is that like how you can see what it's like to see through things if you hold your forearm up to your nose? lol \s
Or like how if your hand is bigger than your face you have cancer
\smack**
Look at something with your elbow.
It’s like that.
I am a mutant so this example doesn't work for me.
What if you close one eye?
You don’t see black… it’s just “nothing”. I believe that is what’s been described as total blindness.
Heard this one before: point your elbow at something and tell me what your elbow sees. Kind of gives you an idea
Blind Person here. Actual ebeicbejwixbwksoykwnwoypfjebfixuebxiejwbxixosbauybahwufbfeo
I'd imagine it looks like nothing.
Nah the brain would still be creating imagery in that part of the brain, it's just the information source has been cut off. It's probably like when your eyes are closed going to bed at night thinking about stuff. Black but maybe some sparklies from nerve activity and whatnot.
I read (or heard?) once that when you're completely blind you don't see black either but more like what one eye sees when you close it, yet leave the other open. It's sort of "nothing" more than it's black.
I read a blind guy’s explanation and he said (paraphrasing) “What do you see when you look out of your knee cap? Is it all black? No? You don’t see anything out of your knee cap because your knee cap doesn’t communicate with your brain that way. Same goes for my eyes.” That really blew my mind
Our brains are very good at adapting. Your nose is useless information being in frame at all times so the brain edits it out. If your eyes stop delivering useful information it makes sense that would not see black but nothing like your nose being invisible unless someone points out you can see your nose 24/7

I would think they still have a visual processing core it's just not receiving any stimulation so it would be black.
This is an incredible tool to help us all understand other people better. There should be a whole series like this.
The vision simulator glasses are from my company lol
Surprised no one asked yet, what’s it called? What do you do?

Both incredibly fascinating and incredibly terrifying. Getting old is no fun and no joke. It feels like we’re already doing so much to try to maintain other types of health, are there dietary things we’re supposed to do for Eyehealth?
My optometrist told me to eat kale. Can't hurt.
Leafy greens for the win. Got it. Thank you.
How do you respond to the posts from people in this thread that showing black spots is inaccurate - rather these regions are filled in with hallucinationed guesses by the blind person's brain?
I go by clinical studies and what low vision specialists (aka my accounts) share with me. But I don’t dismiss what others are saying, every individual is different even if they have the same eye condition.
I'm a web developer, and it's transformative to try to use a website with a screen reader. Accessibility is something that more people should be passionate about. For us, we only prioritized it when the government and Microsoft made us.

This should be in high school health classes. We did some dumbass beer goggles that absolutely were nothing like being drunk but this is awesome.
Can anyone who is blind confirm that these glasses are correct?
I need a way to relate to my wife's tiny hands. She is constantly dropping and breaking stuff and I feel irritated at her. Intellectually I understand it's her baby hands, and it's not that she doesn't care. But I know if I could walk a day in her hands (you know what I mean), it would engender true empathy. I want to be free of the irrational irritation, I walk myself though it in my mind, tell myself all the words and it's fine. But I just don't wanna feel that knee jerk jump of frustration, I want a knee jerk feeling of compassion towards her.
Not sure how to pull this off. Replace everything in our house and make it 40% larger? TV remote, coffee cups, toilet paper. It's just not feasible.
God, all of those look so torturous. Blindness is one of those impairments that I would never wish upon my greatest enemy, especially now that I can better understand what blind people go through on a daily basis.
I wish this guy would make one for Snow Syndrome. I have it badly, no fix. Every day I live with seeing the world like there’s tv static/a grain filter over top, with occasional moments of blindness in portions of my vision.
Also severely vulnerable to light… you know when you look at REAAAALLLY bright headlights from a car at night and it kinda stays in your visions for half a second when you look away?
Try minutes now, and not just bright light, like the light in a conference room for example… awesome.
Apparently it’s something wrong with the way the brain perceives information it gets from the eyes, and not the eyes itself.
I've had mild visual snow my whole life, and I was never entirely certain if it was an issue with my eyes or my brain.
Well, I lost part of my vision in one eye; I have a blind spot that I'm able to perceive. But I still have visual snow in that blind spot! So, now I know it's definitely caused by my brain.
You aren't alone, I have it all my life too, alongside tinnitus. My brain can "forget" both as long as there are other stimuli, but I can't really see the stars during the night for example.
This is what it looks like for anyone wondering. Another example.

Have you ever taken any psychedelics? Some more intense visual distortions on LSD or shrooms can create static-like waves in people's fields of view. I wonder if it would cancel out or magnify the intensity.
I just had cataract surgery and that is an accurate view of my vision pre surgery. Post surgery it is 20/20...
He said 50% of population will get this by age 75. If you get surgery, you reduce your risk of dementia by 30%.

It takes ten minutes to perform and is local anesthesia. It's an easily solved issue that should not affect half of the elderly.
Glaucoma representation made me feel claustrophobic for the first time in my life
To be fair that’s what end-stage glaucoma looks like. There’s a lot of steps to get there usually.
I have diabetic retinopathy and need injections in my eyeballs every 4 months to prevent it from getting worse. It's so scary to think I could fully lose my vision.
Me too. Do you get laser?
I got laser in the beginning, and holy shit that hurts! I've been lucky that the retinopathy hasn't really worsened so we just maintain with injections. Laser again would be if it suddenly got worse. Sucks to be a diabetic and hear a cure is coming "in 5 years", every year, since I was diagnosed in 1997!
Thank god for the injections huh? I worked in a retina clinic, those injections are one of the most amazing things to happen to medicine in a long time.
Left out Retinitis Pigmentosa.
Poke a small hole in a piece of paper and look through it. Basically extreme tunnel vision near the end of its cycle. Very slow degeneration blindness in most cases. I once could drive, now I have basically zero periphery and can only see with one eye and only exactly what I’m looking at.
So sorry to hear that. RP is a horrible disease. Hope you’ve got a good retina doctor!
Yea, I was the cataract person. Now I have 20/20 vision with a little wavy pattern on either side. But it’s all good 👍
I have diabetic retinopathy, it's not like this. It's more like eye floaters but there are a bunch of them going all directions at once. Like there are a bunch of flies around. The spots are never in the same place all the time, and they aren't that big. More smaller spots that pop up more with time.
This seems incredibly misleading.
How so?
Because these are illnesses that cause mostly blindness, AKA "legal blindness."
Usually when we say "blind," we mean people who were born blind and literally see nothing. This video doesn't mention those people. So it can lead to a misconception that "blind" people can partially see, even though many of them can't. It depends on if you define "blind" as legally blind or actually blind.
I've seen some pretty amazing advancements in restoring sight . Basically a camera lens tied to receptors . Look how primitive the medical field was 100 years ago. It bums me out I won't see what amazing advancements will be made in the next 100.
With smartphones, smart watches and more and more breakthroughs about prosthetics being controlled by the brain via a chip, I don’t think we have to wait 100 years for the first brains being able to connect to the internet
Fuck that would be incredibly frustrating
This video made me so uncomfortable.
This should be shown to every kid in high school to reiterate taking care of your eyes. Eye protection is seriously important, even sunglasses.
my grandnan was legally blind. she could just barely make out like 3/4 inch large font bold lettered words if she used a magnifier with a light on it, and even then it was only out of the top corner of her right eye.
she could knit literally with her eyes closed. one year her and her friends knit over 200 or 400 scarves and such for the home for battered women, and made the paper. she didn’t want to be in the photo tho, she didn’t need publicity or recognition.
My grandnan was illegally blind, she was on the run for years. The police could never catch her, so she became quite confident, started taking risks. When they finally caught her by setting up a trap, she didn't see it coming.
While raising awareness for various forms of blindness is a good idea, these glasses do not represent 'what blind people see'. With time the brain will adapt to partial blindness, which no glasses can simulate.
Take macular degeneration. Yes, your central vision is impaired, even absent. But your brain uses details in your peripheral vision to 'stitch together' a complete picture anyway. There's not much indication which assumptions your brain is making might be wrong.
- If you looked directly at a tree on an empty park, you would not see a tree, because your brain would 'stitch' the grass either side together.
- If you looked at an even row of fence-posts and focus on the open gate, you would see a long stretch of fence, because your brain assumes the pattern of posts continues uninterrupted.
- A person walking towards you might look like a slight shimmer as you detect the edges of their clothing, but your brain expects the footpath is still clear until they're nearly on top of you.
- A room seems well-lit, but the sconce on the wall doesn't exist until you turn away from it.
My mother has severe macular degeneration, and these examples are hers. She had to stop cycling because quiet electric cars started 'appearing' in front of her. And she has an Amsler grid to monitor how progression.
Did anyone else just become insanely grateful for their vision?
I went to the eye doctor the other day cause I was seeing a returning black spot from a few weeks ago. Turned out to just be a weird different kind of floater, one that’s dark and fuzzy and not a crystaline worm.
I blind guy I once met has told me that, if you are really really blind, you actually do bot see black, but nothing at all. It is hard to comprehend for us, but it's like there are no eyes. At least I was told so by him.
Wow thanks so much for sharing this
Stevie Wonder dropped and caught his microphone on stage once. This caused a lot of people to call him a faker. Idk what kind of blindness he has but I know his optical nerves work. So he's not that small percentage of people mentioned at the beginning.
I have retinopathy. But instead of black I have white. I would so much rather ir be dark.
There’s also retinitis pigmentosa which is kind of the reverse of the last one shown.
I remember someone here who was blind saying that they don't see black. They see nothing. They tried to explain like "it's like trying to see out of your kneecap, it just isn't there" and I still don't fully understand it but it blew my mind.
my grandmother had macular degenration and I don't think that's a good example of it
She basically just had voids in her visual recognition, it was never diagnosed as if it was dimmed, it was like literal blindspots that she wasn't aware were there
I don’t have a cataract. I’ve got a rincoln continental
It really blew my mind that i totally know nothing about blind people
The vast majority of people don't. It makes things challenging for us to be called fakers because rely heavily on our phones (technology is great, I cannot imagine being visually impaired even 10 years ago)
Most of us can see 'something' but it isn't usual vision. And that 'something' isn't the same for any two people. And it can vary throughout the day, or depending on conditions.
Thanks for being honest, and I hope that helps a bit.
It seems that with all of these there is something physically wrong with the eyes. Is there a surgery for some? I'm pretty sure cataracts have a surgery but I'm not sure about the rest.
Cataracts can be fixed yes. Glaucoma is irreversible. Macular degeneration is too for the most part, but both of these can be halted or slowed if caught on time.
Macular is not reversible. More false information...
That's what I said, it's irreversible like glaucoma
Wet macular degeneration is often partially reversible in modern time, but it takes frequent eye injections to do so
Cataracts can be fixed with surgery. In fact most people, at least in the u.s., will develop them eventually. And bonus, if you were near sighted before, it is often corrected with the cataract surgery.
...can you get a complete eye transplant from a donor?
We don’t have the technology to connect an eye to the optic nerve. There has been limited success with a robot eye that pairs with a brain implant chip.
…and the beer goggles??
Am I going to hell for making this remix?
This just applies to people that are legally blind and not what I consider "actually blind" those people don't see a damn thing. I throw stuff at them all the time, not one has caught a brick yet
Damn, something actually interesting!
What’s the medical explanation for seeing a shitty sidewalk in all these examples?
People use "partially sighted," "legally blind" or similar phrases for these sorts of things, not "blind."
So, not blind then?
Blind means blind.
Many blindnesses could be avoided with a simple annual check-up.
Why full blind people from birth will see black? They never saw nothing, I just assume they just didn't see, like nothing at all, like when you can't smell, 0.
False. I’m completely blind and I definitely disagree with all this. We can’t see. Anything. End of discussion.
This is garbage, stop spreading this crap
Someone doesn't know the difference between blind and visually impaired.
Blind means you see nothing.
The rest of that demonstration is visually impaired.
