I can't wait to hear the answer to this, because I have noticed the exact same thing in my eyes!! Been there over a week now. It's on both sides, and it's a spot, white, but a tiny bit darker than the white of my eyes-it's noticeable. I thought at first it was some parasite in there (HORRORS!), but luckily it does not move around at all. I've rubbed it and it does not move. Very strange!
