The one that started it all, the unmistakable Lazer Face® is the ULTIMATE statement piece utilizing a 2mm thick, 6C base single lens, that is curved on both the horizontal and vertical axis for optimal clarity. The lens is structurally supported by a durable polycarbonate sub-frame, which is positioned entirely behind the lens giving the Lazer Face® it's unique ALL-LENS look when worn. This mass impact and shatter resistant lens is secured to the frame using stainless steel hardware, allowing the Lazer Face® to meet ANSI Z.87 requirements, and Z.87+ with optional add-on side shields. The nose piece features a no-slip rubber-like insert made from extremely resilient and sustainable Hytrel® (TPC-ET thermoplastic elastomer) ensures the glasses stay comfortable in place on the face, while original Heat Wave radius arms wrap them securely around thehead. All parts are replaceable on the Lazer Face®, including the lens, nose piece, frame and arms.
