First of all, fucking WHY? The smoke is one of the most putrid, foul things known to man from what I hear. Second of all, you would have to waste many grams of beautiful shrooms to even get remotely psychoactive effects.
In short, don't fucking do it.
edit: bleh, I should've read the post first. To answer your question, no the smoke won't make you go blind. That is ridiculous. But you shouldn't fucking be smoking mushrooms in the first place.
