These are the aviator sunglasses that use advanced optic technology developed by NASA to protect astronaut’s eyes and make objects appear more vivid. The polarized lenses block blue and violet rays that impair vision yet allow sight-enhancing green, yellow, orange, and red rays to reach the retina. They also help improve visual clarity by blocking 99.9% of harmful UVA and UVB rays, and blue light, while enhancing vision and diminishing distortion. The frame is crafted from memory flex alloy and stainless steel, which allows it to be bent or twisted, yet return to its original shape. The coated lenses resist glare, scratches, dust, and smudges, and repel water. Includes zippered case, cleaning pouch, and anti-fog cleaning kit. Imported. Black/Gold or Silver/Blue. (8 oz.)
