OPTICAL PLASTIC PRODUCT, AND PLASTIC SPECTACLE LENS AND SPECTACLES
First Claim
1. An optical plastic product having an optical multilayer film disposed on one or both surfaces of a base made of plastic, directly or via an intermediate film, whereinthe optical multilayer film includes a tensile-stress high-refractive-index layer having tensile stress as internal stress and made of a high refractive index material, and a low refractive index layer made of a low refractive index material, andthe tensile-stress high-refractive-index layer is disposed with a physical film thickness of not greater than 10 nm, in a first layer as counted from the base side in the optical multilayer film.

Abstract
An optical plastic product has an optical multilayer film formed on one or both surfaces of a base made of plastic, directly or via an intermediate film, wherein the optical multilayer film includes a tensile-stress high-refractive-index layer having tensile stress as internal stress and made of a high refractive index material, and a low refractive index layer made of a low refractive index material, and the tensile-stress high-refractive-index layer is disposed with a physical film thickness of not greater than 10 nm, in a first layer as counted from the base side in the optical multilayer film.
