Abstract

A lens for eyewear is configured to reduce the appearance of scratches on the lens and/or increase the durability of the lens. The lens can include a functional stack bonded to a lens body. The functional stack can include a functional layer, such as a thin film coating, sandwiched between the lens body and an optical-grade transparent film. The functional stack can increase abrasion resistance and environmental durability of the lens, and can reduce the appearance of scratches on the lens. The combined lens body and functional stack can increase the durability of the lens relative to a lens with a thin film coating (e.g., a gradient or mirror stack) on an external surface of the lens.
