You seem to be under the impression that all blindness is exactly the same. There are people who have serious difficulties reading at normal screen distances, but still have enough sight to appreciate a painting.
Yes, and that impression is correct because "blind" means someone who can't see. At all. The people you mention are usually referred to as "visually impaired" or "legally blind".
This thread is about people who need visual accommodations to use websites, not completely blind people exclusively. You're the one who's been talking like they're the same thing.
