Laminated lenses with anti-fogging functionality
First Claim
1. A lens for eyewear comprising:
- an anti-fog layer configured to resist accumulation of condensate, wherein the anti-fog layer comprises a hydrophilic material, wherein the anti-fog layer is proximal to a wearer when the eyewear is worn;
an interface layer comprising an inorganic material with ceramic bulk properties; and
a lens component, wherein the interface layer is configured to facilitate attachment of the anti-fog layer to the lens component.

Abstract
Eyewear can include a laminated lens that has anti-fogging functionality. The lens can include an anti-fog layer configured to resist accumulation of condensate on a posterior surface of the lens and an interface layer comprising a thin layer of inorganic material with ceramic bulk properties. The interface layer can be disposed between the anti-fog layer and an adhesive layer configured to adhere to adjacent layers of the laminated lens. The adhesive layer can be disposed between two lens elements. One of the lens elements can include a polymer layer that provides stiffness to the lens and an electrically conductive layer deposited on the polymer layer. When electric current is applied across the electrically conductive layer via one or more electrodes, the lens can be heated.
