LENS PROCESSING SYSTEM, DEVICE AND METHOD FOR MANAGEMENT OF PROCESSING SIZE, AND METHOD FOR MANUFACTURING SPECTACLE LENS

PROBLEM TO BE SOLVED: To simplify the time and labor of size adjustment in processing to each processing machine, when a plurality of processing machines are present.SOLUTION: A lens processing system includes: a plurality of processing machines 10 for performing the edging of spectacle lenses; and a processing size management device 30 connected to these and used. The processing size management device 30 is provided with a memory means 33 for storing and retaining information concerning processing characteristics in the processing machines 10 in association with types of lens materials and types of processing tools for every model of the processing machines 10. The information stored and retained in the memory means 33 is information obtained by at least one of the plurality of processing machines 10. The processing machine 10 having the same type as at least one of them includes correcting means 12 for correcting parameters for processing, based on the information stored and retained in the memory means 33, when processing the lenses with the processing machine 10.
