Unlike traditional sunglasses that darken your vision, these use optical technology developed by NASA to make objects appear more vivid while blocking 100% of UV rays and shading eyes from sunlight.
Based on the glasses designed by NASA's Jet Propulsion Laboratory to protect astronauts' eyes from solar radiation, the polarized lenses filter blue and violet light rays that can impair vision, yet allow sight-enhancing green, yellow, orange, and red light rays to reach your retina.
As a result, objects appear more distinct and distortion is greatly diminished. The stainless nickel-silver frames have a gunmetal finish, adjustable, non-slip nose pads, and spring hinges. The lenses meet CE, ANSI, and EN1836 standards and regulations for scratch and impact resistance. Includes hard case, soft pouch, and cleaning/maintenance kit.
