Delivering both refined styling and maximized performance, this is the ideal twin-lens mask for skin diving and for scuba diving.
UV420 CUT lens
The UV420 Cut lens is able to block harmful HEV (high-energy 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.
UV420 Cut Aqua Lens
Get the following benefits from UV420 glass Eye Protection … Blocks harmful UV and near infrared wavelengths. Cutting near infrared rays helps preserve the composition of lutein, so important for healthy vision. Brighter field of vision…Overall visibility is effectively enhanced by the bluish tint (aqua color).
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.

An eye protected by a UV420 Cut lens:
Light tends to cause oxidative stress and lutein (pigment) deterioration.
Protection of lutein reduces oxidative stress:less pigment deterioration.

WIDE SIGHT IS SECURED - Inclination 10 degrees
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.
SOFT TOUCH - Skirt with curled lip and integrated strap clip
All-in-one design ensures firm but gentle contact with the face. When you pull on the strap, you get an effective seal that is less likely to leave impressions on your skin.
NO STRESS - Soft damper
Normally, due to pressure squeeze and other causes, mask frames designed to improve the downward arc of vision tend to exert more pressure on the cheekbones. The soft damper relieves this stress.
MINIMIZES WATER POOLING - Drain skirt
The drain skirt design improves water expulsion during mask clearance and minimizes water pooling.
WIDE FIELD OF VIEW - Low volume
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.
EASY ADJUST - DX spec mask buckle
While the mask is fitted, the release buckle and fine pitch strap adjustability make it easy to find the most comfortable fit. Even wearing thick gloves, you can easily adjust the mask using one hand.
