text: do we have creatures living on our eye balls? i've noticed, usually when staring up into a bright clear sky that i can see lots of little dots and squiggles swimming around in front of me. they seem to move around randomly and blinking seems to cause them to move too. am i seeing tiny creatures living on the surface of my eye ball or am i going mad? gah! i know this one!!!! my mom's an optometrist, so i even know the way right answer!!!!!!!!!1 eeeeeeeeeeeeeeeeee!!!!!!!!!!!!!!!!!!!!!   *breathes* okay. they're called "floaters". real artistic, i know. what they are is little bits of protein and whatnot from inside your eyeball that's broken loose (most people have one or two floaters - they break loose when you whack your head on something). if you have a considerable amount of them, do get checked out, but one or two are normal.  blinking makes them move because it moves your eyeball. and they don't move randomly - they're kind of stationary in your eyeball jelly, so when you move your eyes, it looks like they moved, but that's just because you moved your eyes. i.e., if your floater's in the lower left side of your vision, after you move your eye's focus, the floater will still be in the lower left of your vision, even though it's hanging over a new backdrop.
