<P>PROBLEM TO BE SOLVED: To provide an optical article including an anti-reflection layer having low sheet resistance. <P>SOLUTION: A lens 10 includes: a plastic lens base material 1; and a transparent anti-reflection layer 3 formed on the base material 1 through a hard coat layer 2, wherein ion is radiated to the surface of one layer 32 of the anti-reflection layer 3 to introduce oxygen defect and improve the conductivity. The sheet resistance of the lens sample can be lowered to about 12th power or less, and it is possible to provide the optical article having satisfactory anti-static function to prevent adhesion of dust. <P>COPYRIGHT: (C)2011,JPO&INPIT |
