  • METHOD OF MANUFACTURING MULTIFOCAL LENS AND MULTIFOCAL LENS
    Publication number: 20070195263
    Abstract: A multifocal lens includes a group including M layered lenses. M-kinds (M is an integer of two or more) of lens materials having glass deformation point temperatures of At1, At2, . . . , AtM, are used and diluted by a heat press method. A contact surface of an N?1th lens (N is an arbitrary integer of two or more and M or less) contacted with an Nth lens is a concave face, a contact surface of the Nth lens contacted with the N?1th lens is a convex face. The glass deformation point temperatures have a relation of AtN-1>AtN.
