Optical lens coloring system and method of coloring optical lens

摘要

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