Bouton Airborne Safety Glasses feature a sleek and futuristic frameless design that offers a perfect fit and large field of vision. The Anti-Scratch/FogLess™ Coating is treated on the front and back with a clear, scratch-resistant coating for a much harder surface that is more resistant to scratching and eliminates the condensation of moisture on lenses that causes fogging, so your lenses and vision stay clear. Adjustable length temples are rubber co-molded to provide a secure, comfortable fit. Temples are also ratcheted for better angle adjustment. Molded nose bridge design to fit the vast majority of users. Extended wraparound single lens with a molded upper brow guard. Meets ANSI Z87.1+ and CSA Z94.3 Standards.
