UV420 CUT Lens
The UV420 CUT lens is able to block harmful HEV (high-energy visible light in the 400 to 420 nm spectrum) which causes oxidative stress and deterioration of *lutein in your eye. Lutein is said to act as natural sunglasses. It is present as a pigment in the retina, a crucial part of the eye that receives light and allows you to see. The UV420 lens prevents cumulative macular degeneration by blocking 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. Lighting can alter the appearance of a tunnel. Orange light make objects more visible by increasing the contrast of its shadowed edges. White light increases overall visibility by generally illuminating everything brighter. As in the orange-lit tunnel, our previous UV400 Amber lens increases contrast, while the UV420 CUT lens provides a brighter visual such as with white LED light.
Eye Behind an Ordinary Lens
Light tends to cause oxidative stress and lutein (pigment) deterioration. Eye Behind a UV420 CUT Lens Protection of lutein reduces oxidative stress:less pigment deterioration. Two Types of High-Performance Lenses UV420 CUT Aqua Lens UV420 CUT eye protection blocks out harmful UV and near infrared rays. Cutting out near infrared rays helps preserve the composition of lutein which is crucial for healthy vision. Overall visibility is effectively enhanced by the bluish tint offering a brighter field of vision. Super Clear Lens Enables greater clarity than standard glass. Objects are seen more clearly. By rigorously removing impurities from the glass, light transmittance is maximized. Skirt reflections on the lens are also minimized with a clear silicone mask. The UV 420 CUT Difference
Low Volume Volume：
140cc*2 Weight： 246g Low volume further improves the excellent arc of vision you get with the single-lens design. Enjoy a wide view that’s great for any form of diving. *2 Measured using Gull standard procedures
No Center Frame
The benefit of a lens undivided by a center frame is the overlapping of the arcs of vision of the right and left eyes. You get a bright, broad field of view and less feeling of restriction. Made for high performance in diving situations where field of view is crucial.
