OTOH, someone who fights blind voluntarily gives up other things, so I would let him do it.
Ah, but that's where we get horribly sneaky.
If I'm flanked by two rogues four levels higher than me, I close my eyes. Since I have Uncanny Dodge and they're effectively invisible, I don't lose my Dex bonus, and since I'm blind I can't be flanked... therefore I can't be sneak attacked.
Then, on my next action, I open my eyes, make my full attack with no penalties, and then close my eyes again.
The rogues have two options... make their full attacks as normal, with no sneak attack damage, or Ready an attack action to get a single shot in each while my eyes are open.
Under 3.5, I give up any chance to get in an AoO while my eyes are closed, but if they're Readying actions or Full Attacking, they won't be provoking many AoOs anyway...
