Apparatus for grinding eyeglass lens

An eyeglass lens grinding apparatus for grinding right and left eyeglass lenses such that they fit into an eyeglass frame, said apparatus comprising:

• processing information providing means for providing processing information about the right and left eyeglass lenses based on information about a configuration of the eyeglass frame and information about a layout of each eyeglass lens with respect to the eyeglass frame;
• memory means for storing the processing information about the right and left eyeglass lenses even after their processing has ended, and said processing information for one of said right and left eyeglass lenses retrievable after processing said other of said right and left eyeglass lenses;
• corrective information input means for entering corrective information about size correction to modify the processing information, wherein the corrective information input means includes a selection switch for selecting and retrieving processing information to be corrected from the processing information stored in said memory means for said right and left lenses;
• computing means for providing lens corrective processing information based on the entered corrective information and the processing information stored in said memory means;
• grinding means for grinding eyeglass lenses;
• processing control means which controls said grinding means in accordance with said processing information to grind eyeglass lenses, and which controls said grinding means in accordance with said lens corrective processing information to perform corrective processing;
• and
• a switch which deletes all of the processing information, stored in the memory means, for the right and left lenses,
• whereby the corrective processing can be performed on demand after the right and left eyeglass lenses have been processed consecutively based on the processing information provided by said processing information providing means.
