Abstract
A colored plastic lens includes a plastic substrate having first and second surfaces, a resin film with a pigment dispersed therein formed on one of the first and second surfaces of the plastic substrate, and a coating film, preferably a hard coat film, formed on the resin film and the surface of the lens on which the resin film is not formed. A method of forming the colored plastic lens includes providing a plastic substrate having first and second sides, dispersing a pigment in a resin vehicle, coating the pigment dispersed in the resin vehicle on one of the first and second sides of the plastic substrate to thereby form a resin film, and forming a coating film, preferably a hard coat film, on the resin film and the surface of the lens on which the resin film is not formed.
