Contact lens habits and hygiene Never sleep in contact lenses unless advised to do so by an eye care provider. Keep all water away from contact lenses. Avoid showering while wearing contact lenses, remove them before using a hot tub or swimming, and never rinse or store contact lenses in water. Contact lenses and supplies Replace contact lenses as often as recommended by an eye care provider. Discard used solution from the contact lens case and clean it with fresh solution, never water, every day. Store contact lens case upside down with the caps off after each use. Replace the contact lens case at least once every 3 months. Eye care provider involvement Visit an eye care provider as often as recommended by your primary health care provider. Remove contact lenses immediately and call an eye care provider if you are experiencing eye pain, discomfort, redness, or blurred vision. Be prepared Carry a backup pair of glasses with a current prescription in case contact lenses need to be removed.
