The blade-style Sharp Edge is a lightweight pair of range glasses that are ideal for any tactical activity. The flexible and durable soft-touch matte black frame is equipped with soft thermoplastic rubber temple arms and adjustable nose pads to create a comfortable, nonslip fit. The absence of a lower frame prevents sight obstruction, making it great for shooting. Thin temples provide comfort and functionality when worn with a helmet or ear pro and keep a sealed fit with noise reduction headsets. G-15 lens technology was pioneered for U.S. Air Force pilots and features a green-colored tint that has cooling properties for the eyes. These lenses provide excellent contrast and image definition while maintaining a neutral, true-to-life perspective. G-15 lenses are perfect for a variety of bright light conditions. The addition of Vapor Shield military grade anti-fog technology keeps these lenses completely resistant to fog, even in extreme environments. Edge Tactical Eyewear glasses are tested in independent laboratories to ensure their compliance with ANSI Z87.1+2015, Military Ballistic MCEPS GL-PD 10-12, and EN166 F CE standards.
