The Shatterproof Selenite Polycarbonate lenses meet all the MIL-PRF-32432 (GL) Ballistic Standards, ANSI Z87.1-2015 High Velocity and High Mass Impact standards that your profession may require. The flexible form fits your temples with non-slip rubber temple tips that feature a wire core. They can be easily adjusted for the perfect fit with or without hearing protection. The distortion free viewing meets ANSI Z87.1-2015 optical clarity standards, all while providing 100% UVA/UVB protection. The adjustable nosepiece allows the lenses to sit high to provide maximum coverage and an unobstructed view. These glasses also feature a quick release action in which the pivot lock is designed for rapid detachment of temples for ease of changing lenses. Finally the T-Shell premium scratch resistant hard coat exterior helps keep these lenses protected and the Foll anti-fog coating keeps them fog free.
