  • HOLDING STRUCTURES FOR SPECTACLE LENSES, SPECTACLES, AND METHOD OF MANUFACTURING SPECTACLES
    Publication number: 20110037940
    Abstract: A circumferentially elongated flat recessed portion (13) is formed in the outer edge surface (2c-h) of a spectacle lens (2). The distal end of a lens holding portion (9) is bent in a J shape to form an insertion portion (9A). The insertion portion (9A) is inserted into the recessed portion (13) and fixed in position using an adhesive (15). Thus, the spectacle lens (2) can be reliably held by the lens holding portion (9) with strong bonding between the spectacle lens (2) and the lens holding portion (9) free from the possibility of a reduction in bonding strength or fall-off upon twisting.
