<P>PROBLEM TO BE SOLVED: To solve the problem that the impact resistance of a plastic lens obtained by forming a primer layer on a plastic base material, forming a hard coat layer on the primer layer, and forming a thicker anti-reflection film of prescribed layers on the hard coat layer so as to have a convex surface and a concave surface is low. <P>SOLUTION: The primer layer is formed on the plastic base material, and then the hard coat layer is formed on the primer layer, and furthermore, the anti-reflection film is formed on the hard coat layer so that an optical thickness of a specific low-refractive index layer on the convex surface side and an optical thickness of a specific low-refractive index layer on the concave surface side are within a prescribed range, whereby characteristics superior in hardness, film contact, interference color, and impact resistance can be obtained with respect to a convex surface of a plastic lens which is easily scratched. <P>COPYRIGHT: (C)2010,JPO&INPIT |
