Re: Blind man learns Judo I've known ju jitsu people who have taught techniques to blind people. Also for part of my instructor's qualification test I had to pretend that the class was blind and teach them three techniques. It was quite a challenge at the time, but I ended up sticking to close-in locking techniques. The main challenge is keeping the lesson safe. As someone pointed out, however, most blind people have a better sense of space than sighted people with their eyes shut.
