Classy black pin up/diva cat-eye eyeglasses frames adorned with rhinestones, 50s NOS

Sferoflex Demi blonde cateye eyeglasses frames with golden metal bridge, hinges and temples. Very unique at the time were the spring hinges, a patent from Sferoflex, which is still running as a company today for this reason and has been purchased by Luxottica, like most profitable eyewear industries. The spring hinges make the frames stronger and with a better adaptation to the face. Today it seems nothing special, but at the time it was, and these frames were amongst the most expensive. Frames are in perfect condition, new and unworn from deadstock. cal 48-18 Overall width: 12.5 cm Lens width: 4.8 cm Temple length: 13.5 cm
