Abstract
A lens supply system has: an initial shape data obtaining unit that obtains initial shape data of a spectacle lens; a shape data correcting unit that corrects the initial shape data such that, when a base curve of an initial lens manufactured based on the initial shape data is defined as a first base curve, a predetermined lens having a second base curve lower than the first base curve is defined as a target spectacle lens, prismatic effects which light rays in respective visual line directions passing through a center of an eye assumed in optical design receive from the initial lens coincide with or approach prismatic effects which the light rays receive from the target spectacle lens; and a spectacle lens manufacturing unit that manufactures a spectacle lens based on the corrected initial shape data.
