MANTIS LV

Delivering refined styling with maximized performance, this is the ideal twin-lens mask for skin and scuba divers.

Equipped with UV420 lenses and a skirt uniquely designed for increased comfort. MANTIS LV’s exclusive lens shape, low-volume construction, and optimized inclination angle allow for an extended field of view.

High-Performance Lens

• UV420 CUT AR Amber Lens

  UV420 CUT AR lenses offer protection against UV & HEV rays preventing deterioration of Lutein (responsible for protecting the eye tissues from sunlight damage). The amber coloring enhances visibility by increasing contrast to better see objects underwater.

  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.

  

  AR (Anti-Reflection)

  Conventional lenses reflect a significant portion of light, resulting in a lower light transmittance of about 92%. UV420 AR lenses, with single-side AR coating, allow roughly 95% of light to pass through. This ensures a clearer and brighter vision, more akin to the naked eye.
  Anti-reflection is also an important safety feature, facilitating ease of eye contact when underwater.

  

  UV420CUT Lens Function

  Protects eyes from UV rays (up to 400nm),and HEV light (400-420nm), that contribute to oxidative stress and deterioration of lutein*.

  An Eye Behind an Ordinary Lens

  Light tends to cause oxidative stress and lutein (pigment) deterioration.

  An Eye Protected by a UV420 Cut Lens

  Protection of lutein reduces oxidative stress: less pigment deterioration.

  *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.

  Comparing Orange and White (LED) Light Effects in a Tunnel

  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 UV420 amber lens increases contrast.
