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.

Abstract: Systems, devices, and methods for embedding a HOE in an eyeglass lens are described. A method of embedding a HOE in an eyeglass lens includes forming a world-side portion of the eyeglass lens, forming an eye-side portion of the eyeglass lens, physically coupling the eye-side portion of the eyeglass lens to the HOE with a low-temperature optically clear adhesive (“LT-OCA”), and physically coupling the world-side portion of the eyeglass lens to the HOE with LT-OCA. Forming the lens portions may include high-temperature processes, and the HOE may not be damaged by the high-temperature processes since the high-temperature processes may be performed on the lens portions prior to coupling the lens portions to the HOE.

Abstract: Systems, devices, and methods for aligning a diffractive element in a wearable heads-up display (“WHUD”) are described. A WHUD that includes a projector, a transparent combiner, a WHUD frame, and a diffractive optical element (DOE) embedded in the transparent combiner, requires alignment between the DOE and the eye of the user and/or the projector. A WHUD includes a DOE aligned with an eye of a user when the WHUD is worn on the head of the user. A method of aligning a DOE in a WHUD with an eye of a user when the WHUD is worn on a head of a user includes aligning a first part of the WHUD frame with a first part of the face of the user, and aligning the DOE with a second part of the WHUD frame.
