What does a totally blind person see?
A person with total blindness won’t be able to see anything. But a person with low vision may be able to see not only light, but colors and shapes too. However, they may have trouble reading street signs, recognizing faces, or matching colors to each other. If you have low vision, your vision may be unclear or hazy.
Do blind people know darkness?
Went Totally Blind: People who have lost their sight have different experiences. Some describe seeing complete darkness, like being in a cave. Some people see sparks or experience vivid visual hallucinations that may take the form of recognizable shapes, random shapes, and colors, or flashes of light.
How do blind people sleep?
Most blind people with no perception of light, however, experience continual circadian desynchrony through a failure of light information to reach the hypothalamic circadian clock, resulting in cyclical episodes of poor sleep and daytime dysfunction.
Can blind people tell the difference between light and dark?
While only 18 percent of people with significant visual impairments are actually totally blind, most can at least perceive light. In other words, although we cannot see colors, shapes or people, we can still tell the difference between light and dark.
What do totally blind people really see?

While only 18 percent of people with significant visual impairments are actually totally blind, most can at least perceive light.
What does it mean when you have no light perception?
Total blindness describes people with eye disorders who have no light perception (NLP). That is, a person who’s totally blind doesn’t see any light at all. Total blindness can be the result of trauma, injury, or even conditions like end stage glaucoma or end stage diabetic retinopathy.
Does being blind equal being black?
The logical assumption is that when sight is snuffed out, a person must be left in darkness. If you dive under the bed covers you can’t see anything at all. If you close your eyes then everything turns to black. So, blind equals black? It makes sense, right? Apparently not.
