To improve a rate of fitting in a spectacle frame of a spectacle lens after V-block processing and make possible supply of a V-block-processed spectacle lens with stable quality.
A controller 240 for instructing a lens processing machine to apply V-block processing to a spectacle lens on the basis of frame shape data to be output by a spectacle frame measuring machine comprises: recognition means 240a and 240b for recognizing a positional relationship between a groove shape of a spectacle frame for which the frame shape data is measured and a reference measurement point used as a reference when measuring the frame shape data, and recognizing a positional relationship between a reference processing instruction point used as a reference when instructing the lens processing machine to apply the V-block processing and a V-block shape obtained by the V-block processing; and processing amount correction means 240d for correcting a processing amount when instructing the lens processing machine to apply the V-block processing so that the V-block shape fits in the groove shape, on the basis of each positional relationship recognized by the recognition means 240a and 240b.
