Links: Entoptic Phenomena
Do you ever see these little moving shapes in your eye, most noticeable on a clear blue sky?
They're called floaters, and there's not too much you can do about them. I've had the same floater shapes in my eye since I can remember. In a way, they're almost like a part of me - a floating, translucent part of me. :P
Floaters and other types of entoptic phenomena are described here.
I also experience the "blue field entoptic phenomena." Whenever I go to the beach, I see the moving dots the page talks about. I was really worried about that until I read that page. Sometimes the Web can actually teach you something useful.
