The Tusa Visio Pro's lens is protected by a special edition two-piece chrome frame and black surgical grade silicone skirt.
In addition, the M-110SQB-CR features TUSA's patented Quick-Adjust Buckle System, 3-D Anatomical Strap and Round-Edge skirt technologies.

TUSA CrystalView Optical Glass Lens

TUSA's ClearView optical glass lenses provide superior clarity, colour and transmission of light over standard glass lenses used by the competition.
Up to 15% of available light can be lost with a standard glass lens due to impurities and reflectivity. TUSA's ClearView lenses transmit 92% of available light to the diver for clear crisp vision.

Anti-Reflective (A/R) Lens Treatment
Standard glass lenses can reflect up to 15% of available light reducing vision underwater.
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.

UV Lens Treatment
Increased exposure to UV light can damage the eyes especially in marine environments where reflectivity is high. TUSA's UV Lens Treatment provides 100% protection from harmful UVA and UVB rays. Blocking 100% of the ultraviolet spectrum (under 400 nm) provides greater eye protection without sacrificing light transmission or vision.

Tech Tip

Why Black or Opaque Skirt Diving and Snorkelling Masks Are Better

Clear silicone skirts on diving and snorkelling masks are popular because they minimise the claustrophobic feeling some people get when they wear a mask. Nevertheless, clear skirts actually interfere with vision. Extraneous light entering through the clear skirt makes it more difficult for the eye to focus and causes reflections that obscure vision. Demonstrate this by looking out a window from a lighted room at twilight. You will see better by cupping your hands around your eyes as you press your face to the window. For these reasons, knowledgeable scuba divers, spearos, freedivers, underwater photographers, and snorkellers seeking the best possible vision prefer masks with black or opaque silicone skirts.
