They're called "floaters". They are dead cells, bacteria, and other
organic debris within the vitreous or aqueous humor of the eyeball.
People have varying numbers of them, and you tend to collect more of
them as you get older. They drift around by Brownian motion within
the eyeball, and if they come into the eye's focal plane just right,
you can see them as irregular strings or blobs.
