Abstract:
A vision shift amount measuring method includes: forming a reference mark indicating a distance eye point on a surface of a spectacle lens attached to a spectacle frame practically worn by a wearer, and forming a plurality of opaque lines in an area expected to contain a shifted vision on the surface of the spectacle lens with a predetermined space between the adjoining lines; and allowing the wearer wearing the spectacle frame to select the line closest to a position through which the vision passes from the plural formed lines.
