US 5,926,247 A · Method of manufacuturing spectacles, and spectacle frames used therefor

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.

Dependent claims

A spectacle manufacturing method of processing non-processed lenses into shapes conforming with a spectacle frame and setting the processed lenses in said spectacle frame to complete spectacles, said method comprising:

a first step of manufacturing a spectacle frame and of measuring configurations of lens-accommodating portions of the manufactured spectacle frame to obtain frame configuration information representative of the measured configurations;
a second step of storing frame-related information including said frame configuration obtained in the first step in information storage means;
a third step of obtaining prescription values for eves of a spectacle wearer;
a fourth step of reading out said frame-related information stored in said information storage means in the second step;
a fifth step of obtaining, on the basis of information including said frame configuration information obtained in the first step and said prescription values for said spectacle wearer's eyes obtained in the third step, lens processing information necessary for when non-processed lenses are processed into said shapes conforming with said spectacle frame and mounted in said spectacle frame,
a sixth step of processing non-processed lenses in accordance with said lens processing information obtained in the fifth step to produce spectacle lenses fittable into said spectacle frame;
and
a seventh step of setting the produced spectacle lenses in said spectacle frame to complete the spectacles.

A spectacle manufacturing method of obtaining lens processing information, necessary for processing spectacle lenses, on the basis of information including prescription values for eyes of a spectacle wearer and frame configuration information on a spectacle frame said spectacle wearer selects to choose and process spectacle lens material on the basis of the obtained lens processing information for producing spectacle lenses and of setting the produced spectacle lenses in said spectacle frame to manufacture spectacles, said spectacle manufacturing method comprising:

a first step of, on a factory side, manufacturing said spectacle frame and obtaining said frame configuration information on said spectacle frame;
a second step of, on said factory side, storing frame-related information including the obtained frame configuration information in information storage means to allow said frame-related information to be read out therefrom;
a third step of, on said factory side, adding reading information, on the basis of which said frame-related information stored in said storage means is read out therefrom, onto said spectacle frame;
and
a fourth step of obtaining said frame configuration information, needed for obtaining said lens processing information about said spectacle lenses to be set in said spectacle frame said wearer selects, by reading out said frame-related information from said storage means on the basis of said reading information added onto said spectacle frame on a spectacle store side.
