<div> Atomic Aquatics revolutionized the dive industry with UltraClear lenses. Before UltraClear, all dive mask lenses were made from low-quality float glass with a visible green tint caused by iron particles remaining in the glass after processing. These green iron particles significantly block light transmission through the lens. All Atomic Aquatics masks utilize a higher quality optical glass that significantly improves underwater vision allowing up to 96% of light transmission-UltraClear glass. </div> <div> <br /> </div> <div> The UltraClear lens in the Venom mask is made by the Schott Glass Company in Germany. The Venom gives you the highest purity grade UltraClear glass available. That means you get incredible clarity and high light transmission that isnt available in other masks-even those who claim to be ultra-clear. After all, the main reason you dive is to See whats down there! The new Venom dive mask lets you see more&amp; and youll look great doing it. </div> <div> <br /> </div> <div> <b>Features:</b> </div> <div> <ul> <li>New UltraClear Schott Superwite glass lens with exceptional optical clarity.</li> <li>Patented SubFrame design with hydrodynamic styling and no external frame.</li> <li>Double-layer, dual-color silicone skirt keeps the mask comfortably secure.</li> <li>One-window / low volume design for unobstructed forward vision and wide viewing angles.</li> <li>Simple squeeze-to-adjust mask strap</li> <li>Lifetime warranty against frame breakage.</li> </ul> </div>
