Full-frame safety glasses provide an increased level of coverage from dangerous tools to everyday dust and debris. Scratch-resistant lenses filter 99.9 percent of harmful UVA, UVB and UVC rays for safe, outdoor use. Full-frame design features a flexible nylon frame and strong polycarbonate temple construction for increased durability. Nonslip, rubber temple components and nose pads keep these glasses in a comfortable position and resist perspiration. Integrated temple accessory receptors also improve airflow when not in use. For enhanced safety, the temples can be attached to an elastic retainer strap or foam gasket insert (each sold separately). Glasses are tested to ANSI Z87.1+ High Velocity Impact Protection and optical requirements. Glasses are also tested to MIL-PRF-32432 Ballistic Fragmentation, Class 1.
