Method for supplying spectacle lens

Difference between a lens edge circumference and an edged lens circumference is controlled to be always within a prescribed range so that a spectacle lens of a properly finished circumference size can always be supplied.A method of supplying a spectacle lens by bevel-edging an uncut spectacle lens based on specified lens edge shape data includes a lens edging step (S) to rim machine a spectacle lens based on a lens edge shape data and a prescribed edging condition of the spectacle frame, a lens circumference measuring step (S) to measure the circumference of the spectacle lens bevel-edged by the lens edging step, a circumference difference calculating step (S) to calculate difference between the lens circumference obtained by the step of measuring the lens circumference and the lens edge circumference of the spectacle frame, and a correcting step (S to S) to correct the circumference correction value stored for every edging condition so as to put the circumferential difference within a prescribed range.
