Abstract
An eyeglass lens grinding apparatus, which is designed to process an eyeglass lens so that the lens fits into an eyeglass frame. Frame shape data of an eyeglass frame is input, and a lens edge position on the lens is measured based on said frame shape data. Lens processing data is calculated based on the lens edge position and the frame shape data. The processing data is stored. The grinding wheels are controlled to process a plurality of lenses consecutively based on the same processing data until a signal requiring different processing data is issued. If a next set of lenses are to be processed, i.e. a different processing data is required, a made is switch to measure a lens edge position to newly obtain processing data.
