UVB blocking contact lenses effectively block UVA and UVB light. (A) Protective UV-absorbing eyewear, such as sunglasses, alone are not able to protect the ocular surface from UV rays coming from the side direction (depicted in yellow arrows) (B). UV blocking contact lenses offer total protection of the cornea and the limbus and when combined with UV protective eyeware the entire ocular surface is protected. The UV blocking contact lenses tested, ACUVUE OASYS (senofilcon A) offer 10-fold more protection for UVA and 17-fold for UVB, reaching 96% and 100% blocking of UVA (C) and UVB (D) respectively compared to contact lenses without a UV blocker, namely Air Optix Night & Day (lotrafilcon A).
