Summertime may find you sunbathing at the beach, garden or pool. But if you’re a contact lens wearer, there are things you should know about lenses that promise protection against ultraviolet (UV) rays. These contact lenses are not enough to keep your eyes safe from sun damage. Here's what you need to know to safeguard your eyes in all seasons. Contact lenses won't protect your eyes from the sun Contact lenses with various levels of UV protection are now available from brands such as Acuvue, Bausch & Lomb and CooperVision. Class 1 UV-blocking contact lenses claim to block 97% of UV-B and 81% of UV-A rays. But those claims convey a false sense of protection, eye experts say.“Contact lenses with UV-blocking technology may protect the part they cover from harmful radiation, but they leave the outside of the eye — including the eyelid, conjunctiva and surrounding skin — exposed,” says ophthalmologist and Academy member Claudia Perez Straziota, MD, a cornea and refractive surgery specialist. Exposure to UV light can increase your risk of developing several eye and skin conditions, including: growths on the eye, such as pterygium and pinguecula cancers on the conjunctiva, eyelid and/or skin surrounding the eyes such as basal cell carcinoma and squamous cell carcinoma, as well as ocular melanoma earlier or accelerated development of cataracts and age-related macular degeneration photokeratitis or “sunburn” on the cornea or conjunctiva (this is rare) Maximize your sun protection while wearing contact lenses Contact lenses are no substitute for protective UV-absorbing eyewear and head coverings.
