Polycarbonate lens provides impact resistance and 99.9% UVA/UVB protection. Rubber tipped temples and a soft rubber nose piece give these glasses a secure fit for all day wear. Designed with IQuity™ semi-permanent, anti-fog and anti-scratch hydrophilic coating that lasts longer than hydrophobic coatings (washable up to 20 times more). The water-based coating lasts much longer because the anti-fog and anti-scratch properties are built into the lens for long-term wear and durability. Environmentally friendly, non-toxic and non-flammable, unlike highly toxic solvent-based coatings. All IQuity safety eyewear meet the ANSI Z87.1+ requirements for impact resistance.
