ABSTRACT:
A plastic lens comprising the first acrylic hard coated layer formed on the outside surface of a plastic lens base and, on the inside surface, an antifogging coated layer while interposing of the second acrylic hard coated layer is obtained by coating both sides of a plastic lens base with an acrylic hard coating agent, masking the outside surface with a peelable masking agent (e.g., a coating composition containing poly(vinyl chloride) or a vinyl chloride-vinyl acetate copolymer), coating at least the inside surface with an antifogging agent, and removing the masking layer. As the hard coating agent or antifogging agent, use can be made of an ultraviolet-curable resin composition, and as the masking agent, a coating composition containing a poly-(vinyl chloride) or vinyl chloride-vinyl acetate copolymer may be employed.
