The Gemstone Onyx Y85 protective flame resistant foam lined safety glasses series feature a removable foam lining in a matte black nylon frame with adjustable bayonet temples and anti-fog polycarbonate lenses. The most unique feature of the Gemstone Onyx Y85 Series is its dual vent systems. Without the foam carrier, it is a direct vent spectacle; with the foam carrier, it becomes an indirect vent spectacle. Each pair of scratch resistant glasses meets the ANSI Z87.1-2010 high impact standards, absorbs 99.9% of harmful UV rays and comes complete with a black adjustable strap that is easily attached or removed depending on the end users need. Replacement gaskets available (Y85FM).
