Document Type and Number:
Japanese Patent JP2015094804
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To manufacture a spectacle lens of a shape that matches a spectacle frame.SOLUTION: A spectacle lens manufacturing system includes: an order-placing computer that transmits first information about a two-dimensional shape and dimension of an outer periphery of a spectacle lens having at least a lens shape; an order-taking computer that calculates third information about a three-dimensional shape and dimension of the outer periphery of the spectacle lens having the lens shape on the basis of the first information transmitted from the order-placing computer and second information about a curve value of a curve surface of the spectacle lens having the lens shape; and a spectacle lens processing device that manufactures the spectacle lens on the basis of the third information.
