Skullerz Aegir Polarized Anti-Scratch & Anti-Fog Safety Glasses feature an oversized, blade-style design for superior eye protection and maximized field of vision. Tough, scratch-resistant, anti-fog, polycarbonate lenses protect against impacts and filter 99.9 percent of harmful UVA, UVB and UVC rays. High-strength frame is built for durability. Rubberized nose bridge and temples offer nonslip security and resist sweat for all-day comfort. Rubber temples easily bend and re-bend to accommodate a variety of head shapes and fit preferences. Polarized lenses reduce glare and eye fatigue around water, snow and other bright environments. They are useful for those working with dust masks or in extreme temperature change. Safety glasses are tested to ANSI/ISEA Z87.1-2020 High-Velocity Impact Protection and optical requirements. Blue mirror lenses with 15 percent VLT are ideal in outdoor, bright-light and glare conditions.
