ABSTRACT:
To avoid excessive stressing of lenses and still facilitate the attaching and removing of the lens to the rim, a pair of eyeglasses has an improved rim lock member. The rim lock member has a two-parallel wire arrangement and a metal piece slidably movable thereon. The opposite ends of the loop hole of each rim are connected to the two parallel wire ends, and the space of the loop hole can be controlled by moving the metal piece on the two-parallel wire arrangement. Specifically the loop hole of each rim can be reduced by moving the metal piece toward the rim on the two-parallel wire arrangement until the circumferential length of time rim is shortened to wind tightly around the lens, thereby holding the lens fixedly. The bridge of the front of a pair of rimless eyeglasses has a similar parallel wire-and-metal assembly structure.
