Magnifier eyewear features a 1.5 dioper, clear lens that is scratch-resistant and filters 99 percent of U.V. radiation. One-piece wraparound lens will not obstruct your vision. The tight fit allows you maximum safety and almost zero percent of your vision outside lens view. Comfort is enhanced by the flexible temples. Nonslip rubber head grips on the temples are notched and ready for a clip-on breakaway cord (sold separately). Total orbital seal provides superior protection for people needing magnifying lens. Evenly balanced polycarbonate lens features a Duramass scratch-resistant coating. Eyewear meets or exceeds ANSI Z87.1 safety standards
