qbert,
I'm no expert on this, but I found a link suggesting that:
1. There is not much you can do about existing floaters, but the brain learns to ignore them with time.
2. The real problem is how to stop new floaters from occuring. A quick scan of the internet indicates that diets high in sugar, poor blood sugar control and pre-diabetes or diabetes are associated with the formation of eye floaters and cataracts. So it appears that the "paleo" or low carb diet advocated on this blog may help at least prevent new floaters from forming. A low carb diet, with exercise and fasting, will tend to lower insulin and this favors a process called "autophagy" or "self-digestion". Sounds horrible, but it is in fact the natural process by which your cells eliminate damaged (oxidized, glycated or denatured) tissue. Since floaters consist of denatured protein in the vitreous layer of the eye, it is reasonable to hypothesize that lowering your insulin levels will inhibit and perhaps even reverse floaters.
