摘要： A process which enables a plastic lenses having a refractive index of 1.7 or greater and, in particular, plastic lenses having a refractive index of 1.7 to 1.8 to be dyed uniformly to a great density without unevenness, which is, specifically, a process for producing a dyed plastic lens which comprises conducting following steps (1), (2) and (3) in this order: Step (1): a step comprising coating a substrate at 60° C. or lower with an ink comprising a sublimation dye; Step (2): a step comprising decreasing content of water in the ink comprising sublimation dye coating the substrate to 50% by mass or less of the entire ink; and Step (3): a step comprising, after placing a plastic lens in a manner such that a face for dying of the lens and a face of the substrate coated with the ink comprising a sublimation dye face each other, sublimating the sublimation dye in the ink comprising a sublimation dye coating the substrate by heating the substrate obtained after Step (2) under a degree of vacuum of about 1×104 Pa or smaller to dye the plastic lens.
