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. Fog-Off Plus technology combines scratch-resistance on the exterior and enhanced, anti-fog performance on the interior for clear viewing. 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.
