This is an eyeglasses made-to-order system wherein an operator determines eyeglass specifications necessary for ordering eyeglasses, including necessary items relating to each structural member of the eyeglasses, with an interactive system using means including a computer-controlled display screen; wherein any of a plurality of types of basic frame designs prepared in advance is selected from the abovementioned display screen; and the optimum eyeglass specifications reflecting the consumer's preferences can be determined on and ordered from the display screen by arbitrary changes to the structural members of the eyeglasses, including frame type, lens shape, and parts, based on the selected basic frame design. Accordingly, eyeglasses with a design which are more reflective of the eyeglass consumer's preferences can be determined and ordered quickly using only the procedures deemed necessary by the operator.

Eyeglasses made-to-order system

The present invention makes it possible to perform machining that forms holes or grooves for the attachment of parts to the outer circumferential edge surfaces of lenses of various lens patterns, both accurately and with good reproducibility, by means of a simple operation. The spectacle lenses are positioned so that the machining areas of the spectacle lenses are maintained in a fixed positional relationship with the machining reference position of the machining apparatus by using spectacle lens fastening devices which can fasten the spectacle lenses with attached spectacle lens holding jigs in place, and adjust the positions of these spectacle lenses , to cause specified positions on the spectacle lenses to contact the reference surfaces of a positioning reference plate
