More than 90% of blind people can see the sun. In the us blind means you vision cannot be corrected to better than 20/200, without glasses my vision is worse than that, so if I can do it without glasses some blind can as well. (Of course my vision is correctable to perfection)

Interesting, I only ever imagined blindness to be total darkness and absence of sight. One great example among many of how you can't effectively design accommodations for a particular disability without getting input from someone who has that disability.

Fun fact! Unless you have no eyes or no optic nerve, you'll basically always see something. Even 100% blind people can still see shadows, movement, the sun, etc.

Most of the "blind" definition is around driving and reading.

I'm blind with only light perception, but I cannot see movement or shadows. Another fun fact I guess.

Other blind people see a flashing shifting colorful mess in their field of vision. I know someone who can even mentally control the perception of the visual disruption to an extent, like making it flash different colors.

The visual system from the eye to the brain and everything between is incredibly complex and can fail in all kinds of different ways.
