Skullerz Saga Anti-Scratch & Enhanced Anti-Fog Safety Glasses feature a sleek, sporty, frameless design with a wide field of vision. Tough, anti-scratch, anti-fog, polycarbonate lenses protect against impacts and filter 99.9 percent of harmful UVA, UVB and UVC rays. Contoured nose bridge provides a comfortable fit that won't slip or pinch. Flex-fit, nonslip temples reduce pressure and headaches caused by tight-fitting glasses. Temple accessory slots are compatible with attachable lanyards (not included) and improve airflow when not in use. Fog-Off Plus technology delivers scratch-resistance and enhanced, anti-fog performance for clear viewing no matter the job. Impact-resistant safety glasses are tested to ANSI/ISEA Z87.1-2020 High-Velocity Impact Protection and optical requirements. Indoor/outdoor lenses with 50 percent VLT are ideal for indoor, nighttime, hazy and cloudy conditions.
