Abstract
Systems, devices, and methods for embedding a diffractive element in an eyeglass lens are described. A method of embedding a diffractive element in an eyeglass lens includes applying a protective layer to a diffractive element, applying an interface layer to the protective layer, and applying a lens layer to the interface layer. The interface layer and the lens layer are each comprised of a resin material that hardens when cured. The interface layer is of a shape and thickness that adheres well to the protective layer after the interface layer is cured. The lens layer is of a shape and thickness that achieves the desired component shape of the lens after the lens layer is cured.
