Lens Technology
UV 420 Lens Treatment protects against harmful high-energy visible (HEV) light and its potential to damage the Retina.
HEV light is present not only on sunny days but also on overcast days. Therefore, protecting your eyes against UV and HEV light in all weather conditions when diving is imperative.
ANTI-REFLECTIVE (A/R) LENS TREATMENT
TUSA’s Anti-Reflective (A/R) Lens Treatment decreases internal and external reflected light. This reduction increases light transmission to 95% resulting in significantly enhanced colour, clarity, contrast and better overall vision underwater.
CRYSTAL VIEW OPTICAL GLASS
CrystalView optical glass lenses provide superior clarity, colour, and transmission of light over standard glass lenses used by the competition. Due to impurities and reflectivity, up to 15% of available light is lost with a standard glass lens. TUSA’s CrystalView lenses transmit up to 95% of available light to the diver for clear, crisp vision. CrystalView lenses are used in all PRO model’s masks.
