PROBLEM TO BE SOLVED: To provide a device that can measure a lens refracting surface shape with simpler constitution and performs lens processing with high precision.SOLUTION: A spectacle lens processing device includes lens rotating means of rotating a lens chuck shaft, chuck shaft moving means of moving the lens chuck shaft in an axial direction, a processing tool, lens shape measuring means having a gage head holding unit for holding a gage head brought into contact with a lens refracting surface and detecting means of detecting a movement position of the gage head in a lens chuck axial direction, lens moving means of moving a lens relatively in a direction in which the distance between the lens chuck shaft and gage head is varied, and control means of controlling the lens rotating means and lens moving means according to a lens shape so as to control the chuck shaft moving means so that the position of the gage head in the lens chuck axial direction enters a predetermined range during the lens shape measurement. |
