General information about the use of contact lenses

Contact Lenses and UV Light

Recent studies have proved a direct link between ultra-violet (UV) light to the formation of cataracts. Exposure to excessive UV light also results in a condition called photokeratitis. To counter this, many of the contact lenses include a UV blocking agent. This blocker is clear and not visible to the naked eye Moreover, it does not disturb your vision.

The contact lens packaging will typically specify if the product has a UV blocker. If not, you can also ask your eye doctor to verify.

UV blocking contacts are not in any way meant as a substitute for your sunglasses. A contact lens does not cover your whole eye, only the cornea. However, UV-blocking contact lenses do help protect the portion of the white of your eye that is covered from formation of growths such as pingueculae and pterygia. On the other hand, sunglasses cover more of your eye and the parts of your face that surround the eye. That's why contact lenses with UV blockers are designed to complement sunglass use as an added protection.
