Ray-Ban Blazer Multicolor Ambermatic Sunglasses 1 Vintage Ray-Ban Blazer sunglasses feature the rare multicolor red, yellow, and blue high performance nylon frame coupled with Bausch & Lomb Ambermatic lenses, a choice of professional and recreational skiers for over 25 years and stylish enough to wear to everything from formal to casual occasions. The B&L Ambermatic lens was one of the world's first "smart" lenses, with photochromatic properties infused into the glass versus a coating that can wear out or wear off. The lens will darken and lighten in varying light conditions, and the frame is so eye catching you're sure to get questions and complements most every time you wear them. The unisex Ray-Ban Blazer frame measures approximately 5.25" temple to temple, and the lenses measure approximately " x " at the widest points. You'll find the Ray-Ban logo in raised metal relief on the exterior of both ear stems, and the inside of one stem is marked impressed B&L Ray-Ban USA while the other stem is impressed Blazer. OBO
