Full-frame safety glasses quickly convert to sealed goggles to effectively reduce exposure to dust and debris when working in a variety of environments. Scratch-resistant lenses filter 99.9 percent of harmful UVA, UVB and UVC rays for safe, outdoor use. Flexible nylon frame and strong polycarbonate temple construction provide increased durability. Nonslip, rubber temple components and nose pads keep these glasses in a comfortable position and resist perspiration. Glasses and goggles 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.
