The Light Sensitive Aviator Sunglasses

These are the sunglasses preferred by airline pilots and professional drivers for their ability to automatically adjust to changing light conditions, darkening in bright sunlight and lightening in overcast conditions to minimize glare, maximize visibility, and reduce eye fatigue. The glasses use photochromic lenses that block 95% to 100% of harmful UVA and UVB rays, and use an anti-reflective coating to block glare and back reflections, eliminating "veiling glare" caused by blue light waves. Chemically tempered for strength, the lenses are made from distortion-free precision ground and polished optical glass, resulting in scratch-resistant lenses that provide the clearest images available. Each lens has had a steel ball dropped on it from 4' during testing to ensure maximum impact protection, meeting both FDA and ANSI standards for shatter resistance. The unisex frames have a 140mm temple length that fit most faces, and are made of nickel-silver with spring hinges for durability and comfort. 6" W x 2" H. (7 1/2 oz.)
