Patent ID: 7448938

Claim:
A method of supplying a spectacle lens by bevel-edging an uncut spectacle lens based on lens edge shape data of a specified spectacle frame, the method comprising: a lens edging step of bevel-edging the spectacle lens based on the lens edge shape data of the spectacle frame, a predetermined edging condition selected from a plurality of edging conditions, and a circumference correction value that is stored for every edging condition and that is used for obtaining a lens edge circumference of the spectacle frame as a circumference of the spectacle lens, every time bevel-edging order of the spectacle lens occurs; a lens circumference measuring step of measuring the circumference of the spectacle lens which is bevel-edged in the lens edging step; a circumferential difference calculating step of obtaining a circumferential difference between the lens circumference which is obtained in the lens circumference measuring step and the lens edge circumference of the spectacle frame; and a correcting step of correcting the circumference correction value so as to keep the circumferential difference within a prescribed range.
