Abstract
A method for producing a mold for molding a lens wherein the upper surface of a glass material to be molded is molded by a thermal sag method using a continuous heating furnace. A mold having a curvature distribution on the molding surface is used, the highest temperature direction from the geometric center of the molding surface to the highest temperature point in the furnace is determined in one or more regions by measuring the temperature at a plurality of measuring points on the molding surface and the mold is rotated during the forming of the mold in which an eyeglass lens is subsequently molded.
