These Pyramex Avante® safety glasses come with a cord which can be used for convenience and easy storage. Aside from its cord convenience, these glasses provide reliable protection against 99.9% of harmful UVA/UVB rays with its hard-coated polycarbonate lenses. The lenses are also highly scratch-resistant and protect the wearer from dust, the wind, and other forms of airborne debris. Moisture? No problem! These frames won’t fog since they’re highly-ventilated. And no slipping either with the built-in rubber nose pads. The Avante safety glasses have straight back, flexible temples, and are contoured for a comfortable fit.
