Take the next step in comfort with SecureFit 400 Series Protective Eyewear. It features Pressure Diffusion Temple technology; soft, one-piece nose bridge; and dual-injected temples for optimal comfort. Curved temples apply pressure to the less sensitive portion of your head instead of your temples. Slotted ribs allow the temples to flex and self-adjust to your head size. Clear, anti-fog polycarbonate lenses absorb 99.9 percent of UVA/UVB/UVC rays. 2.5 plus reading diopter helps workers who have difficulty reading small print or engage in small, detailed work. Protective eyewear meets ANSI Z87 plus for impact-resistance and CSA Z94.3 requirements.
