PURPOSE:To calculate accurately and output data after lens grinding work by inputting optical data of lenses of glasses, data of materials of lenses, data of the shape of a frame, etc. CONSTITUTION:Prescribed data is inputted from a data input part 220 to a data processing part 240, and processing results are outputted to an output part 280 after processing. Data 222 of materials of lenses, data 224 of refracting powers of lenses, data 226 of positions of optical axes of lenses, and data 228 of the position of edge thickness of lenses are inputted from the input part 220, and data 36 is inseted from a frame shape detecting part 100. Processings for arithmetic 242 of curved surface function of lenses, arithmetic 246 of weight, arithmetic 248 of edge thickness, and shape data generation 244 are performed in the processing part 240. In the output part 280, information of required glasses are printed by a printer 282 or outputted onto a CRT 286. Consequently, lenses after lens grinding work are grasped without an actual work. |
