An ordering terminal () installed on an order side of a spectacle lens has a correction function concerning a measurement error measured by a spectacle frame shape measurement device (), and transmits information necessary for machining the spectacle lens including the spectacle frame shape information to a spectacle lens manufacture control device () in a factory. When correcting the measurement error, the circumference of a reference frame () for which a reference circumference as a reference is determined in advance is measured by the spectacle frame shape measurement device (). A measurement circumference obtained on the basis of a measurement value of the circumference is compared with the reference circumference, and a correction value which corrects the spectacle frame shape information such that the measurement circumference approaches the reference circumference is employed as the correction value of the spectacle frame shape measurement device (). A measurement error of the lens frame of a spectacle frame () in which the spectacle lens is to be actually mounted is corrected using the correction value. Hence, the measurement error of the spectacle frame shape measurement device () need not be corrected on the factory.
