Skullerz Baldr Anti-Scratch & Enhanced Anti-Fog Safety Glasses feature a full-frame design and nonslip, rubber temples to keep glasses secure while resisting sweat. Tough, anti-scratch, anti-fog, polycarbonate lenses protect against impacts and filter 99.9 percent of harmful UVA, UVB and UVC rays. Durable frame bends and flexes without breaking. Integrated accessory receptors at each temple improve airflow when not in use. For added safety, attach an elastic retainer strap or foam gasket insert (none included) to the temples. Fog-Off Plus technology combines durable scratch-resistance and enhanced, anti-fog performance for clear viewing. Impact-resistant safety glasses are tested to ANSI/ISEA Z87.1-2020 High-Velocity Impact Protection and optical requirements. They are also tested to MIL-PRF-32432 Ballistic Fragmentation Class 1. Indoor/outdoor lenses with 50 percent VLT are perfect for indoor, nighttime, hazy and cloudy conditions.
