Contact lenses can be convenient, but they must be used carefully. The Centers for Disease Control and Prevention explains that poor contact lens hygiene can increase the risk of eye infections, including serious infections that may affect vision. Read the guidance here: CDC contact lens safety guidance.
Contact lenses sit directly on the eye surface. This means hygiene is very important. A small mistake repeated every day can create risk.
Always wash and dry your hands before touching lenses. Do not use tap water to clean lenses. Do not put lenses in the mouth. Water and saliva can carry germs that may harm the eye.
Use only the solution recommended for your lenses. Do not reuse old solution in the case. Empty the case, rinse it with fresh solution if advised, and let it air dry.
Do not sleep in contact lenses unless your eye-care professional has specifically told you that your lenses are designed for overnight use. Sleeping in lenses can increase infection risk.
Do not continue wearing lenses if your eyes are red, painful, watery, sensitive to light or blurry. Remove the lenses and get advice.
Replace lenses on schedule. Daily, monthly and other lenses are made for different use periods. Wearing them longer than advised can increase deposits and discomfort.
Children and teenagers who use contact lenses need clear instructions and parental support. Good habits should start from the first day.
