Abstract:
The present invention is a method for producing a spectacle lens from a lens material, and includes: a marking step (step S10) of marking an identification mark for identifying the spectacle lens, and a processing information mark which is used to process a lens blank and includes a tray identification 2D code, a tray identification code, a shape line and a position mark by forming a hole or a groove in a convex surface of the lens material by laser; and a concave surface machining processing step (step S13) of reading the processing information mark, and machining a concave surface of the lens blank based on the read processing information mark.
