Ray-Ban Vintage Sidestreet Mirrored Sunglasses Bausch & Lomb

Ray-Ban Vintage Sidestreet Mirrored Sunglasses Bausch & Lomb  Please see last photo for slight wear to left lens. Otherwise amazing condition. Does not come with case.   The highly reflective Bausch & Lomb G-31 mirrored mineral glass lens was only used in a few vintage B&L Ray-Ban styles and mostly in their aviators, so the W2320 from the Sidestreet line is one of the few styles where you can get that iconic lens in a non-aviator.   The unisex Ray-Ban W2320 frame measuring approximately 5.25 temple to temple and G-31 silver mirror lenses measuring approximately 2.0 x 1.375 at the widest points with right lens laser etched Ray-Ban and both lenses laser etched BL near the hinges.   The rear of the nose bridge is impressed B&L Ray-Ban, the inside of one ear stem is marked B&L Ray-Ban, and on one ear pad has W2320 YSAS, though it is slightly worn off. It's a hard to find style from the early 1990’s.
