Abstract: Provided is a method for producing an optical lens in which a processed pattern can be accurately formed on a lens surface at a predetermined position of a lens substrate without limiting the material. A mark adapted to perform position alignment is formed outside a lens region set in a lens substrate (11). A masking layer (21) is pattern-formed above one principal surface of the lens substrate (11) by an inkjet method while formation position of the masking layer (21) is controlled with the mark as a reference, wherein the masking layer (21) has an aperture pattern (21a) at a predetermined position in the lens region. A selective process with respect to a surface exposed from the aperture pattern (21a) of the masking layer (21) is performed by performing a process from above the masking layer (21). The masking layer (21) is removed from above the lens substrate (11) to form a transparent pattern (19a), as the processed pattern, by the selective process on the side of the one principal surface of the lens substrate (11).

Abstract: A dyeing device dyes a resin body by vaporizing and depositing a sublimation dye adhered to a dyeing base to a resin body provided in an installing unit and fixing the dye to the resin body. The dyeing device lowers the pressure inside a closed chamber that closes the periphery of the resin body by a pump (S27). In the state where the adhesion surface of the dyeing base to which the dye is adhered faces the resin body without contact, by heating the dye adhered to the dyeing base inside the closed chamber of which the pressure is lowered, the dye is sublimated, vaporized, and deposited on the resin body (S28). The pressure inside the closed chamber is raised higher than the pressure at the vaporizing and depositing time (S30). By irradiating the resin body on which the dye is vaporized and deposited with electromagnetic wave, the resin body is heated and the dye is and fixed (S36).
