摘要：PROBLEM To provide a plastic optical product and a plastic lens for spectaclesthat have an optical multilayer film but are excellent in heat resistance. SOLUTION In aplastic optical product, an optical multilayer film 3 having seven layers is formed on asurface of a plastic substrate 1 directly or with an interlayer 2 interposed therebetween.In the layers of the optical multilayer film 3, a layer on the plastic substrate 1 side is a lowrefractive index layer, low refractive index layers and high refractive index layers arealternately disposed. At least the high refractive index layer at the center containssubstoichiometric titanium oxide. In a plastic lens for spectacles belonging to such aplastic optical product, the plastic substrate 1 is a plastic lens substrate for spectacles,the interlayer 2 is a hard coat film, and the optical multilayer film 3 is an anti-reflectivefilm.
