They greatly reduce harmful UV radiation transmitting to the corneal surface and into the eye. One thing to remember is: UV-absorbing contact lenses are not a substitute for protective UV eyewear such as UV-absorbing sunglasses or goggles because they do not totaly cover the eye and general area. You should still use UV-absorbing eyewear as directed. Warning: Lengthy exposure to UV radiation is a risk factor related to cataracts. The degree of risk is based on a many things such as environmental conditions (cloud cover, geography, altitude ) and lifestyle factors (time spent outdoors and the nature of that activity). UV-Blocking contact lenses help against harmful UV rays, but formal studies have not been done to prove wearing UV-Blocking contact lenses helps reduce the risk of cataracts or other ocular problems. Ask your contact lens fitter for more information. |
