Eyewear with multiple functional layers

Abstract

Embodiments disclosed herein include eyewear that has one or more laminates applied to a lens body. In some embodiments, the lens body is constructed from a substantially rigid material having a curved shape. The lens body can have any desired curvature, including, for example, cylindrical, spherical or toroidal. A laminate can include a substantially flexible substrate and one or more functional layers or coatings applied to the substrate. In addition, one or more functional layers or coatings can be applied directly to the lens body. In certain embodiments, a bonding layer bonds a laminate to a convex and/or concave surface of the lens body. Examples of functional layers or coatings that can be applied to a laminate include anti-reflection coatings, interference stacks, hard coatings, flash mirrors, anti-static coatings, anti-fog coatings, other functional layers, or a combination of functional layers.
