Replace your contact lens case every two to three months

Lens cases get dirty, just like a toothbrush, says Steinemann. The forefinger and thumb method means you dont have to actually touch your eye. Place your hand or a towel under your eye to catch the lens. Place your forefinger on the center of the upper lid, and your thumb on the center of the lower lid and force a blink. The lens should fall out onto your hand or the towel.
