UV420 CUT lens
The UV420 Cut lens is able to block harmful HEV (highenergy visible light in 400 to 420 nm spectrum) which causes oxidative stress and deterioration of lutein.* * People say that lutein acts like natural sunglasses. It is present as a pigment in the retina, the crucial part of the eye that receives light and lets you see. Here, helping to prevent cumulative macular degeneration, it blocks harmful light and has an anti-oxidant effect. Lutein is destroyed when it absorbs harmful light. Its presence in the retina is limited and, because the body cannot make lutein, it can only be replaced by eating lutein-rich food.
