I know exactly what you are talking about. This is something in the eyes that you've had from birth. Everyone does. My eye doctor said it was something that everyone needs for some reason (I forget why) until their eyes develop. I asked him because I was curious myself. The things you are seeing are on the inside of your eyeballs. If you notice a significant accumulation of them, go see an eyedoctor. Otherwise, they are harmless and everyone has them.
Ok, ive got another thing i can see in my eyes. But this is diffrent. If i squint my eyes, i can see this, "thing" its hard to explain. Its shape is kinda like a lightning bolt, its all jaggedy like that. And it look like its made up of tiny round things like bubbles. I cant really look directly at it because its fixed at a point beyond my direct view. So when i move my eyes it moves too. Does anybody know what it is?? If you dont know what im talking about, do this:
Look at something bright. Like daylight or a white paper. And squint enough to where your eyelashes cover your whole view but you can still see. Then still your eyes, and in the tangle of eyelashes, you should see it. Its kinda clear in color, and i already mentioned its look as best i can.
