Patent attributes
An eyeglass lens processing method for processing a hole for attaching a rimless frame to an eyeglass lens, the method includes: selecting a pattern used for a processing from a plurality of hole patterns; selecting a first drilling in which an angle of the processed hole is normal at least to a lens surface of a demo lens or a second drilling in which the angle of the processed hole is normal to a lens surface of the eyeglass lens; and when the first drilling is selected, (a) inputting a surface curve of the demo lens, (b) inputting hole position data of the demo lens for the selected pattern, (c) determining an hole angle and a hole position for the eyeglass lens based on the surface curve of the demo lens and the hole position data to obtain drilling data.
