    摘要: A lens grinding method of the present invention includes a first step for finding a lens-edge thickness over the en­tire circumference of a lens-edge vector radius locus of a lens to be cut , a second step for finding a lens-edge vertex position information for dividing the lens-edge into a desired ratio over the entire circumference thereof, and a third step for V-edge edging the lens-edge based on the V-­edge vertex position information. Also, a lens grinding ap­paratus of the present invention includes measuring means (12) for finding a lens-edge thickness over the entire circumference of a lens-edge vector radius locus of a lens to be cut , in­put means (16) for inputting a desired ratio, calculating means (15) for finding a positional information of a V-edge vertex for dividing the lens-edge at the input ratio over the entire circumference thereof, and controlling means for V-edge edging the lens-edge based on the V-edge vertex positional information.
    And according to the lens grinding method and the ap­paratus for carrying out the method, as the lens-edge thick­ness is measured over the entire circumference of the lens-­edge and the movement of the lens in the Z-axis direction is controlled such that the V-edge is formed at a desired ratio over the entire circumference of the lens-edge, the V-edge can be desirably positioned even if a lens having an aspheri­cal refracting surface like a progressive multifocus lens.
