There's absolutely nothing. I've been blind my entire life, so I have no concept of vision. My eyes are always closed, and even if I manually force them open, there's nothing except an uncomfortable feeling which most likely stems from keeping my eyelids open.

Since I have no concept of vision, I have nothing to compare it to. I can feel my eyes are a part of my body, but that's about it. They serve no other purpose. My brain has never experienced visual input, so there's just nothing there. I imagine it's quite different for someone with low vision or someone who had full vision and either had it reduced or taken away completely because you still have an idea in your mind. Maybe that makes sense?

What I see, is quite plainly, nothing.  I was born blind, and thus have never seen a thing.  That's the best I can honestly say.  Of course, it is hard to conceptualise nothing, because even as a concept, nothing becomes something.  As close as you can get to this is to ask yourself, what is inside an empty box?
That doesn't mean look around the interior of the box, either.  It just means what it is.  What's inside an empty box?  If it is truly empty?  There is nothing in it.  That's what I see.  Some people call it darkness because they need to find some way to understand it.  I feel this is a misrepresentation, because from all I've ever heard sighted people say you can clearly distinguish between light and darkness, thus making darkness something you can see, and something is not nothing.

its like asking a deaf person to describe the sound, the brain cant abel to form the idea of the something that it never experienced
i've seen light in the passed, though it dicipaded over time, though i still can see it if i consentrate on it, though you dont notice the loss since its loozing gradualy

What do I see? I don't see at all. I don't have that sense. I don't see darkness, I don't see blackness, I don't see clearness, because I don't have the sense of sight. I don't see nothing either, because I don't see. I have zero/zero eye acuity in both eyes and always have.
Also, kinda off topic, but I feel like 2020 jokes are going to get really old, really fast next year. Thoughts?

I have had the same experience as chris. Open or closed my eyes give me no sense of anything.

hi,
Well, for me when My eyes are closed I don't really see anything. When open, I only see light, just enough to tell if say, a b*lb is on / off or if the sun is out, and only when my right eye is open.

I had light perception for twenty years.
Back then, when I closed my eyes, it was dim, like the sun was heavily filtered. When my eyes were open, I could see different qualities of light - sunny, stormy, snow clouds. Obviously, someone had to tell me what they were, but I could distinguish them.

Now I can't see anything. I lost my light perception withint welve hours.
When my eyes are open, it's 99.99999% dark, almost as if my optic nerve is trying so hard to see light that it remembers. But my retinas won't cooperate.
When I close my eyes now, it's blackness.

Totally blind since birth here.

First, dreams. I don't see in my dreams, having never had the feedback to establish what should be happening there. Sometimes I can taste or smell things, but mostly it's audible and tactile feedback.
Second, light. I don't see light, but if you shine a flashlight in my face, it hurts. I can't stare at the sun while in a car because it makes me squint. I think it's the heat on my eyeballs or something. When I go to the dentist, they have to give me those glasses that help protect your eyes; probably just run-of-the-mill sunglasses.
So I don't see anything. Not black, not dark, not anything.

If you want to explain it to a sighted person, get them to perform the following experiment. This isn't perfect but it's as close as they're gonna get.
1. Close both your eyes.
2. Open one eye of your choosing, while keeping the other closed.
3. What do you see out of your closed eye?

Do not explain the following until -after the experiment. It is imperative that they do this experiment "blind", as it were.

Generally speaking, someone with usable vision will focus on what's available. The brain is synaptically greedy in cases like this, and selective. If you perform the above experiment, what's going to happen is that the brain is going to flood one side of your field of vision (the open-eye side) with the input it normally gets, and for whatever reason it shuts off the other side completely, because there's no input there. My partner told me about this, I've tried it on well over a dozen people now, and virtually every single one of them says some version of "What the hell? It's like my eye didn't even exist!". It just...ceases to feed input, so the brain forgets it.
And then, of course, you tell them that this is what you see every day, all the time, out of both eyes, without exception.

The issue is, sighted people are not going to understand that concept. If they close their eyes, and it's sunny out, they'll see a sort of peculiar reddish darkness which is the sun shining through their closed eyelids. Even in pitch black, sighted people believe they see darkness or blackness. They are contrasting it against what they normally see. You have to short-circuit that comparison with an experiment like the one I described in a previous post, or else they're still going to stare and go "Uh, I don't really get it".

when you have a defect, you can't think about the fixed defect

Have you ever gone to the dentist and pulled a tooth? in99% of the cases your lips were numbed. Of course, to unleash your curiosity, you bit your lips because you wanted to know what was going on. When you realised you didn't feel anything, you most likely bit your lips harder because you wanted to discover how far it could go. The same situation happens with sight. The whole sense doesn't work; that is, it doesn't perform the function it is designed for. That's how I can explain it to anyone both visually impaired or sighted.
The concept of darkness is completely wrong. If you see darkness it means you can see something. There is some kind of existence or presence or activity in darkness. However, if you're fully blind, you can't even experience the darkness we think of.

I don't smell or taste anything in my dreams. Smell and taste honestly aren't that important in my view. My perception of the world is 99% sound with a little bit of tactile thrown in.

Jade, That's an interesting experiment. I'll have to try it on some people at some point. That's still the best way I can explain it... there's nothing. It's not necessarily a bad thing, it's just what it is. I like to think of it like not having knowledge of something in my brain. I don't know what I'm missing because I don't have it or care. I'd be really curious to know what people think after going from full vision to none at all. I won't include visually impaired, because you aren't blind, your vision is impaired. You still have at least some concept of vision or light, so it's not the same. I'm not visually impaired, I'm blind. My vision is nonfunctional, not slightly impaired. Anyway, I wonder what that must be like? I'm sure the concept of vision is still in the brain, but since the eyes are unable to communicate with the brain anymore, what happens? I assume someone in that situation would say nothing as well, but I have no idea.
