ABSTRACT:
The method produces a plastic lens with an antireflection film which have the advantages of good adhesion of the antireflection film to any type of hard coat film that underlies it and good abrasion resistance and provides a plastic lens with an antireflection film. The method includes the steps of applying water or an aqueous solution to a plastic lens with an organosilicon compound-containing hard coat film to form a liquid film of water or the aqueous solution on the surface of the hard coat film, then allowing ozone gas to contact with the liquid film to treat the surface of the hard coat film with the ozone gas, and thereafter forming an antireflection film on the surface of the hard coat film through vapor deposition.
