The Skullerz® Kvasir Safety Glasses are versatile medium frame glasses, named after the Norse God of Poetry. These protective work safety sunglasses feature tough scratch-resistant lenses filter 99.9 percent of harmful UVA, UVB and UVC rays to keep your eyes safe in the sun. The durable frames bend and flex without breaking. Non-slip rubber temples keep the glasses secure and prevent slipping. The integrated accessory receptors at each temple also improve airflow when not in use. For added safety, an elastic retainer strap or foam gasket insert (both sold separately) can be attached to the temples. TESTED & APPROVED These impact-resistant safety glasses are tested to ANSI Z87.1+ High-Velocity Impact Protection and optical requirements. ANSI Z87.1 is the US standard for Personal Eye and Face Protection Devices and is listed on the frame. Skullerz® glasses are also tested to MIL-PRF-32432 Ballistic Fragmentation, Class 1, which is the US Military Combat Eye Protection System Performance Specification for eyewear. To pass the military standard, safety glasses must withstand a steel projectile shot at 660 ft / 201m per second which is 4x faster than the Z87+ standard. Lenses must not puncture, crack or shatter. Frames must retain the lenses and not break. These good looking safety sunglasses are great for protecting your eyes during outdoor work like construction, carpentry/woodworking or landscaping.
