ABSTRACT:
A method for dyeing an optical component such as a lens or filter. A coating of dyeing solution is formed on a surface of a lens and the lens is subjected to a nonuniform heating treatment in dependence on the position within the surface to obtain the desired color density gradient of the lens. In accordance with the positions within such surface, a nonuniform integrated heating amount distribution provides the desired color density gradient with excellent reproducibility.
