Designed with a little extra, these sunglasses provide a matte black frame with Polarizes Blue Mirror lens. Constructed with shatterproof Selenite polycarbonate lenses, they meet the ANSI Z87.1-2010 high velocity and high mass impact standards as well as the US Federal OSHA 1910.133 standards. They provide 100% UVA-UVB protection with distortion-free clarity. The T-Shell lens coating resists scratching in extreme conditions, and the removable facial cavity seal protects your eyes from fine dust, pollen, irritants, as well as peripheral light. The polarized blue lens color absorbs reflections across the mirror surface and aids in diminishing glare. They are ideal for bright conditions and allow 12-15% light transmission. Other features include a black zippered clamshell case, a leash cord with rubber temple grips, a microfiber cleaning cloth, and an instruction card. They fit head sizes medium to large. Available in brown.
