Lens for vehicle e.g. car, rearview mirror, has two coating layers including specific reflectivity and coated on respective surfaces of glass substrate, and anti-scraping coating layer coated on one of coating layers

摘要

The lens has a coating layer (20) including a specific reflectivity and coated on one surface of a glass substrate (10) and defining a transmission zone (21) that is not covered by the layer (20). Another coating layer (40) with a specific reflectivity is coated on whole area of another surface of the substrate. A back layer (50) is covered on the latter coating layer (40) and defines a transmission zone (51) that is not covered by the back layer. An anti-knocking coating layer (60) is covered on the back layer, and an anti-scraping coating layer (30) is coated on the former coating layer.
