re: How to fix a blind man up with a woman

From a woman's perspective is tell you this. Most women have a caretaker instinct, and if your friend is charming and funny and okay with life, then I don't see a lot of women not being able to overlook his ability to not see. What I think the biggest red flag is in what you described, is the fact that he's a grown man that lives with his mother and isn't holding down some sort of job, even if it doesn't pay the bills, at least it would get him out of the house and make him productive and aware of the world in a more visceral way.
Does he talk about wanting a girlfriend? If you guys are very close then it shouldn't be too hard for you to explain to him how much women value confidence and independence in a man, and that learning those things would help him meet someone who can see past what he can't. good luck to you.
