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 color, clarity, contrast and better overall vision underwater.
Corrective Lenses are offered on several styles of masks. This option allows the diver to choose right and left lens powers in both a variety of diopters for maximum flexibility and for a custom fit.
Quick-Adjust Buckle System
The Quick-Adjust Buckle System incorporates a newly-designed low-profile buckle. The result is a compact, lightweight, technologically advanced mask design that can be easily and quickly adjusted for a perfect fit.
Round Edge Skirt
TUSA’s Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The “planar fit, instead of linear fit” silicone skirt maintains great fit and unprecedented comfort.
UV Lens Treatment
TUSA’s UV Lens Treatment provides 100% protection from harmful UVA and UVB rays. Blocking of the ultraviolet spectrum (under 400nm) provides greater eye protection without sacrificing light transmission or vision.
