I agree with rfsapiens, this doctor sounds like a douche, sorry but it's true, reminds me of my own doctor whom I visited 2 weeks ago and laughed at my problem

NO psychiatrist, I don't believe in psychiatrists, and I don't believe in anything that "treats" your "mental" problems.

But this is a whole other issue, and we're talking about floaters here which has NOTHING to do with your brain or some other stuff, it's something that exists, IT'S THERE, you don't "imagine" it, it's there in your eyes floating around

and no, NOT everyone has floaters, most people don't have floaters, I've talked to many people here in Greece and some even laughed at me...

change doctors, don't even waste any more time on this crap

just a friendly advise because I've been there... twice..
