DEFINITION

Classification: 351/90

(under subclass 41) Subject matter wherein lens holding rims connected by a bridge are divided or separated at one point on their periphery.

(1) Note. Usually the rims are split at their temporal sides and have endpieces or lugs which serve to lock the rim members around the lenses and also carry temple supporting hinges. The above rims may be formed from metal or plastic material. The rim-splits may be in line with, above or set at an angle to the center of the lenses.
