What makes our new glass so special? Atomic Aquatics has revolutionized the diving industry with its lenses. Prior to UltraClear, all scuba 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 the transmission of light through the lens. All Atomic Aquatics goggles use premium optical glass which significantly improves underwater vision Our UltraClear PLUS lens in the VENOM snorkel mask is made by the Schott Glass Company in Germany. The Venom gives you the highest purity grade UltraClear glass available. This means you get incredible clarity and high light transmission that isn't available in other goggles, even those that claim to be ultra - clear. This mask has been manufactured in accordance with the requirements of the EC 2016 / 425 regulation for PPE (category 1) according to standard NF EN 16805.
