If you get flashes of light in one of your eyes (particularly if middle-aged or older)...

13. Yes--but another common cause of floaters is dehydration.

I tend to get dehydrated easily, and this has caused me to suffer from floaters occasionally (I do get my eyes checked regularly, though). In each case thus far, my floaters were caused by dehydration, and drinking water made them go away.

Another common effect of dehydration is muscle crams--especially in the calves, ankles, and feet. Many people who suffer such cramps don't realize that might be the reason why.

Especially for those of us (and especially as we age) who don't want to have to run to the bathroom all the time, or who tend to get nauseated if we drink too much liquid at once, dehydration is a constant concern.

I can't drink more than 2 or 3 ounces of water at once without getting nauseated, so I have to be reminding myself all the time to drink a few swallows.
