ABSTRACT:
A method of manufacturing spectacles by obtaining accurate frame shape information without performing a frame shape measurement in the spectacle store. In this method, frame shape information is first obtained after a spectacle frame is manufactured in a factory. Moreover, frame-related information, which includes the obtained frame shape information, or readout information, according to which this frame-related information is read out, is preliminarily added to the spectacle frame. Thereafter, in a spectacle store, the frame-related information is read from the spectacle itself or from a storage unit or the like by using the information added to the spectacle frame as a key. Thus, frame shape information, which is needed when obtaining lens processing information, is obtained therein. The present invention further provides a spectacle frame for use in this method.
