These things, do they seem to float quickly in one place and then gradually float down? If you move your eye, do they seem to follow the direction of your eye though not precisely? Do they look like short dark strings or dots or dust bunnies sometimes surrounded by a liquid-transparent-aura-like distortion? Is it almost impossible to focus on them (Only see them indirectly while relaxingly looking at something else)?
If yes to all the above, I have those. I was told they were eye floaters (Only one eye has it). Though later I told my optometrist and she said I should not be able to see them.
Now I know she was wrong. I found this site that has a simulation you can download and install:

You can add floaters and move the mouse around to simulate eye movement and, in turn, see how the floaters move accordingly.
Mine look like dust strings.
