I go on the computer A LOT! I am 13, I go on several hours a day. I was curios if all of a sudden your vision can just dissapear. I woke up this morning and I was like hmm something isn't feeling right then I was like, not it's not. Wait I think that I am going blind for a milisecond each few seconds, then I began to panic. IS it possible to go blind for a milisecond each few seconds, why would this happen. I don't think I am going blind but since it's for a milisecond you really couldn't notice. So what are the signs before you go blind. my eyes are always kind of watery from the computer, thanks guys.
