Styled with beautiful curves, boasting high performance, whether you are scuba diving or skin diving, this single-lens mask is ideal.
Less than 400nm of ultraviolet rays of UV-A are cut 98%.Cutting near infrared rays helps preserve the composition of lutein.
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.
How a tunnel looks with different colored light Orange light makes objects more visible by in increasing the contrast of shadowed edges. White light increases overall visibility by generally lighting everything more brightly. As in the orange-lit tunnel, a UV400 amber lens increases contrast. Meanwhile, a UV420 lens lets everything remain brighter overall. White LED light
Light tends to cause oxidative stress and lutein (pigment) deterioration.
Protection of lutein reduces oxidative stress:less pigment deterioration.
