Skullerz Odin Anti-Scratch & Enhanced Anti-Fog Safety Glasses feature a durable, full-frame design that bends and flexes without breaking. Tough, anti-scratch, anti-fog, polycarbonate lenses protect against impacts and filter 99.9 percent of harmful UVA, UVB and UVC rays. Nonslip, rubber nose piece and rubber temples keep glasses secure while resisting sweat. Integrated accessory receptors at each temple improve airflow when not in use. Fog-Off Plus technology delivers scratch-resistance and enhanced, anti-fog performance for improved clarity and durability. They are useful for those working with dust masks or in extreme temperature change. 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.
