I've never trained in anything, but I want to start just to learn/have fun - I wouldn't plan to ever compete. I am interested in muay thai/bjj, and there is a place nearby that offers lessons in both. My only problem is that I wear glasses, and without them I can't see at all. My eyes are very sensitive so I've never gotten contacts, and I feel if I wanted to start training I would need to get contacts. Will it be too hard to train having glasses, and if I can't wear contacts I guess there isn't much hope for me?
