Side shield for eyeglasses with spring-hinge temple bar
View Patent ↗A side shield for eyeglasses with a spring-hinge temple bar comprising a side wall having a rear edge, front edge, and inside surface. The side shield has a relief structure extending forwardly from the rear edge of the side shield. A fastening structure is located on the relief structure towards the rear edge of the side shield, the fastening structure securing the relief structure to the temple bar of the eyeglasses. The relief structure allows outward deflection of the spring-hinge temple bar when biased outwardly without significantly displacing the side shield from its normal assembled position.
