Designed to be worn as regular safety glasses or as safety goggles by removing the temples, attaching the included strap and adding the removable foam gasket for a dust-beating seal. These safety glasses feature tough anti-scratch and anti-fog polycarbonate lenses to protect against impacts and filter 99.9 percent of harmful UVA, UVB and UVC rays. Available in a variety of lenses to suit a range of tasks and light environments. The durable frames bend and flex without breaking. Non-slip rubber temples keep the glasses secure and resist sweat.
