Spectacle lens manufacturing method and spectacle lens manufacturing system

A spectacle lens manufacturing system, comprising:

• an order placement-side computer processing and transmitting information required to order a spectacle lens including frame shape information;
• a manufacturing-side computer acquiring information required to manufacture the spectacle lens-related to the order by receiving the information transmitted by the order placement-side computer;
• and
• a spectacle lens manufacturing device manufacturing the spectacle lens-related to the order that is processed to have a shape settable in a frame by performing processes including formations of a curved surface and edge shape on a plastic material based on the information acquired by the manufacturing-side computer;
• wherein said spectacle lens manufacturing device uses, as the plastic material of a processing target, a lens blank being a partly finished product of which both surfaces are not yet processed to have a curved surface satisfying an ultimate optical specification but have a predetermined surface shape,
• wherein a processing center of the. lens. blank matches with a frame center of the edge shape to be processed, wherein said spectacle lens manufacturing device selects, out of plural lens blank of different outside diameters and/or lens thicknesses prepared in advance, the lens blank having the outside diameter and/or lens thickness size(s) allowing an appropriate processing for the spectacle lens-related to the order,
• wherein the selection of the outside diameter of the lens blank is conducted by specifying based on a distance from a frame center to a frame and the spectacle lens-related to the order is manufactured by processing the selected lens blank, and
• wherein the curved surface formation is performed to both the surfaces of the lens blank selected by the selection.
