<P>PROBLEM TO BE SOLVED: To provide a plastic lens including an anti-reflection layer made of an organic material, which is applicable to substrates in a wide range from a highly versatile low-refractive index substrate to a high-refractive index substrate. <P>SOLUTION: A plastic lens 10 includes a base material 1 made of plastics, a hard coat layer 2, and the anti-reflection layer made of the organic material where a first anti-reflection layer 3 being a lower layer and a second anti-reflection layer 4 being an upper layer are laminated. A thickness of at least one of two anti-reflection layers 3 and 4 is <100 nm, and a refractive index x of the first anti-reflection layer 3 and a refractive index y of the second anti-reflection layer 4 satisfy relations of x>y and a formula (1). <P>COPYRIGHT: (C)2010,JPO&INPIT |
