Abstract: A lens coupling structure couples a bridge or a temple to a lens of rimless eyeglasses. A bridge or a temple is coupled through a flanged bush to the lens which is formed with a screw hole and a recess. The coupling portion of the bridge or temple and the flanged bush are formed with a screw hole. A fixing screw extends through the bridge or temple, the flanged bush and the lens. The flanged bush has a flange and a cylindrical portion received in the hole formed in the lens. The corresponding portion of the bridge or temple has a protrusion adapted to be received in a recess formed in the flanged bush. The protrusion may be provided on the fixing screw or a seating plate mounted between the flanged bush and the bridge or temple.
