Wear contacts? A full 99% of us don't clean them properly, a 2012 study found. Here's a quick refresher in lens hygiene: Don't sleep in lenses! Research shows it's about eight times riskier to sleep in them than without them. Do take them out before swimming or showering. Water can get trapped under your contact lens, causing a fungal infection. Do rub your lenses, even if your solution says "no-rub," just to be sure you've gotten the dirt off.
