DEFINITION
Classification: 351/69
(under subclass 65) Subject matter including a resilient bridge or a bridge having resilient portions, the lenses being capable of swinging movement so that a separating motion of the nose grips is produced.
(1) Note. The above noted spring-bridges may have loops arranged in front or in the rear of the lens planes whereby the elasticity of the bridge material produces pressure on the nose grip to retain the glasses in position.
