Abstract:
A lens dyeing method comprising the steps of: (a) determining a print area to be formed on a dyeing base body based on information entered to dye a predetermined area of a surface of a lens to be dyed with desired hue and almost uniform color density so that the print area has a diameter larger than that of the lens surface area and the color density of the print area concentrically changes from a central portion to a peripheral portion in a stepwise or linear manner; (b) applying a dyeing ink containing a sublimable dye onto the base body to form the determined print area on one surface of the base body; and (c) placing the base body and the lens so that the print area formed surface and the lens surface area to be dyed face each other in noncontact relation under substantially a vacuum condition, and heating the base body to deposit the dye onto the lens.
