First off, I am certainly not trying to discourage creativity or squash your hopes. But honestly, and this goes for anything from a permanant ailment like being mute or blind to giving yourself an insanity for no real reason, starting with a major detriments sounds really cool, and can be great RP if done really well, but eventually will always get to be a hassle if done on the long term. Almost anyone I've ever seen do this has eventually wanted to find a way to reverse it, and the fact that players can't fix this problem can be frustrating when they have the IG ability to do so. Trying to find a way to reverse it once its been going on for 6 months can also feel contrived.
For blindness in particular, I would think you would be restricted to the above requirements. Even if not, you'd never be able to read anything, so that knocks out puzzles or fun RP things and even writing on the IG boards (when healers and priests can fix blindness, I doubt Breill has been invented in the KR world). You'd never be able to use ranged abilities. Any Lore skill that required you to know something's appearance is out (monster lores, animal lores, etc). Metagaming would become an issue because when you CAN see things, its hard enough to pretend you don't see them normally, let alone if you can never see anything. And finally, no matter how see through that blind fold is, you will see nothing through it at night on a dark lit path or in the dimly lit inn.
Like I said, not trying to be discouraging, but those are just some of the real world issues I can see besides the listed limitations.
