The blade-style Sharp Edge safety glasses from Edge Tactical Eyewear have a flexible, durable matte black half frame with soft thermoplastic rubber temple arms and adjustable nose pads for a comfortable, nonslip fit. The absence of a lower frame prevents sight obstruction, making the Sharp Edge ideal for many applications including shooting. Thin temples help provide comfort, functionality, and a sealed fit when worn with a helmet or noise-canceling headset. Smoke lenses provide the perfect all-around lens tint for bright light conditions and block sunrays without color distortion. The addition of military-grade Vapor Shield anti-fog technology keeps lenses completely fog free, even in extreme environments.
