Abstract
A manufacturing method of a spectacle lens improving a manufacturing yield and a production efficiency is provided. The manufacturing method of the spectacle lens in which necessary information for a frame machining of a spectacle lens (progressive-power lens) including spectacle rim related information is obtained, and both surfaces of a convex surface and a concave surface are edge/polish machined from a spectacle lens blanks. When the convex surface or the concave surface is polish machined, and thereafter, the next surface is machined, the spectacle rim related information and layout information of the edge machining are obtained, and first provisional reference position markstoand second provisional reference position markstoguiding a geometrical horizontal reference and a geometrical perpendicular reference of the lens are inscribed at positions outside of an edge shapeas identification marks for the machined surface being polished as a provisional reference marking process, an optical layout is performed for the surface to be machined next based on these provisional reference position marks to perform a lens block to a lens machining tool.
