  • Dyeing method of dyeing plastic lens, dyeing device and dyeing jig
    Patent number: 6554873
    Abstract: A dyeing method of dyeing a plastic lens includes: a step of placing the lens in a predetermined position in a vacuum vapor-deposition device; a step of placing base bodies to be used for a dyeing operation in the vapor-deposition device, each of the base bodies being applied with dyeing solutions each containing a dissolved or fine-grained dispersed sublimatable dye to form a dye application area on each base body, and the base bodies being arranged in opposite positions to each other with respect to the lens so that the dye application area faces each surface of the lens without contact therewith; and a step of heating the base bodies by heat sources under vacuum in the vapor-deposition device, thereby sublimating the dye of the dye application areas to vapor-deposit the sublimated dye on the lens.
