Plastic lens for spectacles

Abstract

Provided is a plastic lens, for spectacles, which inhibits occurrence of abnormal outer appearance and has antibacterial property. A plastic lens 1 for spectacles includes: a plastic base 2; and a dielectric multilayer film 4 formed on a film formation surface M of the base 2. The dielectric multilayer film 4 includes one or more low refractive index dielectric layers 6, one or more high refractive index dielectric layers 8, and an antibacterial layer 10. The antibacterial layer 10 is a dielectric layer containing metal ion-carrying zeolite, and is disposed closer to an air side than all of the low refractive index dielectric layers 6 and all of the high refractive index dielectric layers 8 are. A physical film thickness of the antibacterial layer 10 is less than 50 nm.
