PLASTIC OPTICAL PRODUCT AND PLASTIC SPECTACLE LENS

A plastic optical product 1 includes optical multilayer films 6 formed via intermediate films 4 on both surfaces of a plastic base 2. In each optical multilayer film 6, SiO2 layers 10 made of SiO2 and ZrO2 layers 12 made of ZrO2 alternate such that a total number of the SiO2 layers 10 and the ZrO2 layers 12 is seven and a layer closest to the base 2 is the SiO2 layer. The SiO2 layer 10 disposed at a third layer L3 counting from the base 2 has a physical film thickness of not less than 210 nm and not greater than 270 nm. The ZrO2 layer 12 disposed at a second layer L2 counting from the base 2 has a physical film thickness of not less than 7 nm and not greater than 12 nm.
