Subject: Can 'floaters,' debris in intraocular fluids, vary in shape among people?

We have been comparing what we see within our own eyeballs when we lay on 
our backs and stare up at a monochromatic sky.  I've always thought of 
these "floaters" as bits of cell debris or proteins and to me they seem 
elongated and fuzzy, like fine roots. My son and wife, on the other hand, 
see round objects, or spheres.  So we ask:  Is this variation due to age, 
gender, genetics, what we ate or drank yesterday?  What are these objects 
we see?  Does their quantity or quality say anything about our vision or 
general health?  Do they ebb and flow or are they constant?  Finally, do 
they adversely affect our vision?  Thank you.  Fans of MAD SCIENTIST.`
