Research Abstract

Although it is not a lot of ultraviolet rays penetrate into the eye via the lens-back reflection of sunglasses, it may possible to induce ocular injury by invades ultraviolet rays from back side.
This kind of lens-back reflected UV cannot protect by sunglasses frame.
Non-UV-reflection courting effectively reduced 80% of ocular UV penetration from back side.
