ABSTRACT:
It is difficult to efficiently fabricate optical lenses on which gradation coloring is finely implemented. Gradation coloring is implemented on optical lenses by using an optical lens coloring system having an optical lens holding device for holding an optical lens, a coloring agent discharging device provided with one or a plurality of nozzles for discharging coloring agent for coloring the optical lens, and a relative position control device for controlling a relative position of the optical lens holding device and the coloring agent discharging device. The relative position control device controls the relative position of the optical lens holding device and the coloring agent discharging device such that coloring agent discharged out of the coloring agent discharging device arrives at a predetermined plane substantially from a direction normal to a predetermined plane of an optical lens held by the optical lens holding device.
