text: eye floaters at age 20? how can that be if someone if in perfect health and several doctors told him all is good? i know they don't go away again, but still, it's scary. can they get worse during major hormonal changes? are they inherited?  any advise? though eye floaters can occasionally be a symptom of something serious, they are generally annoying, but harmless.  i have had floaters for as long as i can remember, definitely since i was your age.  here are a couple of websites that should help you figure out if you need to get them checked.  i hope this helps.
