Method for supplying lens of eyeglasses

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 2 ) 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 3 ) to measure the circumference of the spectacle lens bevel-edged by the lens edging step, a circumference difference calculating step (S 4 ) 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 5 to S 11 ) to correct the circumference correction value stored for every edging condition so as to put the circumferential difference within a prescribed range.
