Patent ID: 8295961

Claim:
A spectacle lens supply system including a spectacle frame shape measurement device which three-dimensionally measures a lens frame shape of a spectacle frame to generate three-dimensional spectacle frame shape information, an ordering terminal which generates order information based on the spectacle frame shape information generated by said spectacle frame shape measurement device and transmits the order information to a spectacle lens manufacturer, and a spectacle lens manufacture control device which generates machining information on the spectacle lens based on the order information transmitted from said ordering terminal, wherein said spectacle frame shape measurement device changes depending on an installation place, said ordering terminal comprises a measurement data correction unit which corrects a three-dimensional spectacle frame circumference using a correction value of a circumference of an inner peripheral surface of a lens of a spectacle frame corresponding to a machine type of said spectacle frame shape measurement device, the three-dimensional spectacle frame circumference being calculated from the spectacle frame shape information generated by said spectacle frame shape measurement device, said measurement data correction unit i) measures a right frame and a left frame of a reference frame having a predetermined reference circumference value by said spectacle frame shape measurement device to obtain three-dimensional shape measurement data then calculates a three-dimensional circumference value from the obtained measurement data, ii) calculates the three-dimensional circumference value a plurality of times to obtain a plurality of circumference values, iii) measures and calculates an average measurement circumference of the plurality of circumference values for each of the right frame and the left frame, iv) calculates an error between the calculated average measurement circumference and the predetermined reference circumference value for each of the right frame and the left frame, v) obtains an average value of the errors of right and left circumferences, and vi) outputs, as the correction value, a value obtained by dividing the obtained average value by 2π, and the spectacle frame shape data serving as the order information transmitted from said ordering terminal to said spectacle lens manufacture control device includes a circumference of a spectacle frame corrected by said measurement data correction unit.
