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.

2 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.

Superclear 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.

Specifications:

Volume: 110cc Weight: 220g

Inherits the form of the Mantis, but with reduced mask volume and even wider up‒down and L‒R arcs of vision. Wherever you dive, see across a wider field of view.

Left-Right: 117° Up-Down: 103° Inclination: 10

The inclination angle and shape of the lens work together to extend the downward field of vision. You can see better through the arc down to chest level, which is where most diving tasks are carried out.
