Squiggly lines?

Whenever I look in the sky I see these sqiggly lines adjectives over the sky. Can anyone explain this?Squiggly lines?
You may sometimes see small specks or clouds moving in your paddock of vision. They are call floaters. You can often see them when looking at a plain perspective, like a blank wall or blue sky. Floaters are certainly tiny clumps of gel or cells inside the vitreous, the clear jelly-like fluid that fill the inside of your eye.
Floaters may look like specks, strands, web or other shapes. Actually, what you are seeing are the shadows of floaters cast on the retina, the light-sensitive cut of the eye.
I see it sometimes too...are u tired, exausted, sort of overheated when u see, because thats when i see them..
it might be stuff on your eyes. if you look at something and concentrate you can see the dust on your eyes and because it's so close to your eye it's big.i think near has to be wispy on your eye though so it's hard to see inside
these are call floaters. floaters tend to move as your eye moves and will settle at he bottom of your eye eventually. i've gotten pretty annoyed with them because every time i try to focus on one, it'd slowly drift away from my focus...and so i can never really center contained by on one.
floaters are part of the aging process. as the outer gel-like section of your eye, aka the vitreous, ages, it shrinks. with the shrinking, it get stringy, or squiggly, therefore cast shadows on your retina. the floaters you see are really just the shadows.
