I have been amused/entertained my my floaters at least since the
first grade. (Extremely near sighted if that makes a difference.)

My understanding has always been that they are 'loose' cells floating
in the vitreous humor just in front of the retina, casting a shadow
thereon. Sometimes form strings of cells.
