<p>A method for supplying the lens of eyeglasses having a correct finish circumferential length at all times by managing the difference between the circumferential length of lens shape of the frame and the circumferential length of a processed lens to fall within a correct range at all times. The method for supplying the lens of eyeglasses while processing the circumferential edge of a not yet processed lens of eyeglasses based on the specified lens shape data of a frame, comprises a step (S2) for processing the circumferential edge of the lens of eyeglasses based on the lens shape data of the frame and specified processing conditions, a step (S3) for measuring the circumferential length of the lens subjected to processing of the circumferential edge by this lens processing step, a step (S4) for calculating the difference between the circumferential length of lens determined by the circumferential length measuring step and the circumferential length of lens shape of the frame, and steps (S5-S11) for correcting the circumferential length correction value stored for each processing condition such that the difference of the circumferential length falls within a specified range.</p> |
