Premium polarized lens with a frosted finish. NIR lens technology is a polarized diffuse reflector that reduces internal reflections within the lens allowing for noticeably sharper clarity, while at the same time protecting the lens from scratching or exposure to harmful environmental conditions. Constructed from CR-39, our NIR lenses block 100% of harmful UV light and meet the optical and impact resistance requirements of ANSI z80.3. NIR lenses have oleophobic coatings on the front and back surfaces to resist oil and moisture and to make cleaning easier. The result is a durable lens with outstanding optics and a unique satin finish appearance.
