I have some vision in one eye and I’m totally blind in the other. It’s literally as if you tried to look at something with the back of your hand or as you said your elbow. How can you describe what it’s like when there is nothing to describe. Any description of vision is going to involve descriptors such as color, shading, etc. If you have never been able to perceive the stimulus symbolized by these descriptors you cannot explain it. Please forgive how redundant that was but I’m too tired to go back and edit.

First, A good amount of blind people (unless they are weakened by the culture of being offended at everything) are not offended at the word see. The vocabulary does not change simply because of a lack of sight. To answer your question however, I see nothing. I don't know what black is unless it has been described to me which it has. I have floaters which are basically flashing lights that don't stop flashing but are scientifically parts of my damaged eyes floating around in the fluid. I don't always remember my dreams though I don't doubt that they have to do with either being incredibly wealthy or pritty girls but of course, I am 20 years old so it could be different for someone older. I hope this answers your question.

I can only perceive light. It's all I've ever known. I can almost always do more in my dreams than I can in real life, but there's never any extra visual input there. Sometimes I inexplicably know things whilst dreaming that, logically, I could only have picked up visually, but again there's no extra sense or anything.

I maintained I wouldn't want to see if I had the option for almost 2 decades. I was born blind and, having studied plenty of psycology, sociology, neurolinguistics and biology I had a pretty good idea that having to re-wire my brain would be a long, perhaps an impossible process. Sighted eye specialists cannot fathom that I can't consciously control my eye movement for example, even though this is learned behaviour from infancy and a little thought would save us all the embarrassment.

This question is asked nearly every day on Quora, too. Is it so hard to imagine?

I either don’t dream or don’t remember them.

I can see light and shadows.
