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 LENS.

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.

The TUSA mask features a round mold, special cross-sectionally shaped skirt fitting line (the outer end part of the silicone skirt touching the face) and molded by rolling the edge to the outside. When the skirt portion of the mask touches the face, the conventional mask is fitted with thin edge lines (Fig. 1), whereas with the TUSA mask, round-edge skirt is fitted on the face (Fig. 2), resulting in a soft-fit suppressing pressure and reducing creasing left on the face. This “planar fit, instead of linear fit” silicone skirt maintains a great seal 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.
