GULL Vader UV420
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.
Two Types of High-Performance Lenses
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.
Water is most likely to flood the nose and mouth area when gaps open in the seal between mask and skin. This may happen, for example, if the mask rides up on the face, if leaking occurs at the cheeks by use of a mouthpiece, or at the corners of the mouth when grinning underwater. Here, the silicone form is optimized to avoid compromising the seal from facial muscle movement, maintaining a secured fit and great feel.

Even while inheriting the form of the VADER, the low-volume design makes it easier to exhale into the mask for equalization and mask clearing.
