<p>Aims to reduce the types of blanks such as a semi-finished lens blank, materials, and processing time. A spectacle lens design device 201 disposed at a factory 200 on a manufacturing side and a lens processing device connected thereto block an applicable semi-finished lens blank or lens blank so that a reference surface thereof tilts at a predetermined angle using a numerical-control curve generator based on order information sent from an order terminal 101 disposed at an spectacle store 100 on a order-placement side, and form both surfaces of a plastic material so that a geometric center of an edge shape positions at a center of a circle of a circular lens to thereby satisfy an optical specification of the spectacle lens-related to the order, and next, the circular lens is processed to have the edge shape of the spectacle lens-related to the order to thereby obtain the spectacle lens-related to the order.</p> |
