ABSTRACT:
An improved joint structure of frameless spectacles for connecting a joint section of a temple or a bridge to an associated lens is described. In order to improve productivity requiring no soldering and to prevent causing no stress in the lens, a bolt is inserted in an engagement aperture of the joint section of the temple or bridge, and in an engagement aperture made in the temple-to-lens or bridge-to-lens jointing area of the lens to be tightened by an associated nut. The engagement apertures and the bolt having such a shape that relative rotation may be prevented between the joint section, the lens and the bolt.
