Do blind people see black?
Just as blind people do not sense the color black, we do not sense anything at all in place of our lack of sensations for magnetic fields or ultraviolet light. We don’t know what we’re missing. To try to understand what it might be like to be blind, think about how it “looks” behind your head.

What if you accidentally look at the sun?
First, staring directly at the sun can damage a part of the retina — which is responsible for the center of your vision — causing a condition called solar retinopathy. Solar retinopathy is like a sunburn on the retina, a layer of tissue at the back of your eye, Habash tells BuzzFeed Health.
Can naked eye see solar eclipse?
But according to NASA and four other science and medical organizations, it’s OK to look at a total solar eclipse with the naked eye — but only when the face of the sun is totally obscured by the moon. A total solar eclipse happens when the central disk of the sun is completely covered by the moon.

Why can we look at the moon but not the sun?
This means that the moon is still up there, but we can’t see it in the daytime, because all of the sun’s light is getting reflected away from us. As the moon continues in its orbit around the Earth, away from the sun, increasingly more of its sunlit surface is visible.
Can you really go blind from looking at the sun?
You might not go blind by staring at the Sun, but please don’t test it! It’s possible, but the hazard is often exaggerated. Even at midday, a normal eye will only let in enough light to heat the retina by about 4°C. You need at least 10°C to cause thermal damage.
How long would it take to go blind staring at the sun?
Permanent retinal damage can occur when someone looks at the sun for 100 seconds or less. This is under two minutes. Ultimately, how long it takes for damage to occur depends on several factors, such as the dilation of the pupil and the sun’s intensity on that specific day.
