These safety glasses are engineered with an innovative molding process that actually allows the frame to serve as a shock absorber that can diffuse and deflect impact. A ventilation channel between the frame and brow bumper directs airflow under the lens to reduce moisture build-up and fogging. 3-position ratchet lens inclination system with adjustable length temples allows you a custom fit. Uvextreme® anti-fog coating.
