▎ 摘　　要

NOVELTY - Ophthalmic lens comprises an organic substrate having a front main face and a rear main face, and a multilayered interferential coating, which is coated on at least one of the front main face and the rear main face, where the multilayered interferential coating comprises at least one layer based on graphene. USE - The ophthalmic lens is useful in a spectacle lens, such as a polarized lens, a photochromic lens or a solar lens. ADVANTAGE - The ophthalmic lens has excellent electrical conductivity, impart antistatic performance, excellent barrier properties, diffusion barrier against oxygen and/or water, antireflective or reflective properties over visible range or infrared/near infrared or UV, abrasion and scratch resistance, and antifog properties, enhances stability of each layer, avoids dust deposition and is easy to clean. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing the lens, involving depositing the multilayered interferential coating on the organic substrate by chemical vapor deposition.
