Abstract: A process is provided whereby a photocurable coating agent is applied to a surface of a plastic lens having a central area less than 2 mm in thickness and thinner than the peripheral area, and the coating agent is cured to produce an objective coated plastic lens without any special cooling apparatus, with high productivity and without deforming the lens. The process for producing a lens includes: holding a lens on a lens holder, the lens having an uncured coating of a photocurable composition on its surface, the lens holder having a lens-contact member composed of an elastic material, the lens-contact member having a surface configuration substantially conforming with a back surface of the lens, the lens being held such that the back surface of the lens is in close contact with the lens-contact part; and curing the uncured coating by irradiation.
