Black Retro-Vintage Acetate Cat-Eye Tinted Sunglasses with 。Such a gorgeous pair of browline cat eye sunglasses/eyeglass frames. 1 pair available. A catty browline that mimics a Shuron or Rayban frame. A well made frame in acetate and silver tone hardware that you won\'t find in any department store. Discontinued 1990\'s line. Self adjusting nose pads. Gradient UV lenses tinted in a purply color. Temple marked 51-18-145, but I measured the width of the lens across the center of the frame coming up with 48mm rather than 51mm. Please read all the measurements below and compare them to a pair you already wear for size comparison. Refer to diagram which shows you how to measure yours, it\'s where I measured these. Just relying on your eye size or stamped size NEVER indicates a sure fit. Space between the hinges is VERY important for a good fit too.
