If your contact lenses case is cracked or otherwise damaged, replace it immediately. Otherwise, if you've had the case more than three months, it's time for a new one. Lens cases can harbor germs and timely replacement lowers the risk of eye problems.
Replacing the case regularly could help protect your eyes from keratitis, a painful condition that leads to about 1 million doctor visits every year. Keratitis can cause ulcers on the cornea or even vision loss, and can occur when your cornea is injured and becomes vulnerable to infection from a virus or bacteria, fungi, or parasites in water.
To protect your lenses—and your eyes—change your contact lenses on schedule. (Tip: Write the date on the bottom with a marker.) And never wear them in the shower or pool, or overnight.
