Antireflective and Hard Multicoat Design for Allyl Diglycol Carbonate Plastic Spectacle Lenses

A design of coating with single, double, and three-layers for allyl diglycol carbonate (CR-39) spectacle lenses has been done. The coating included anti-reflection (AR) layers for back and front surfaces which allow the transmission to reach 99 % of incident light on the eye. This design shows spectacle lenses of higher contrast images, decreasing ghost images, and little driving glare at night as well as more cosmetic. The anti-reflection layers increased scratch resistance, and cleanability, and make lenses nearly invisible and durable Keywords: AR coating, thin-film coating, plastic glasses, hard multi-coating.
