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.
Claims15
A method of embedding a holographic optical element (“HOE”) in an eyeglass lens for use in a wearable heads-up display, the method comprising:
- forming an eye-side portion of the eyeglass lens;
- forming a world-side portion of the eyeglass lens;
- physically coupling a world-side surface of the eye-side portion of the eyeglass lens to an eye-side surface of the HOE with a first layer of low-temperature optically clear adhesive (“LT-OCA”);
- and
- physically coupling an eye-side surface of the world-side portion of the eyeglass lens to a world-side surface of the HOE with a second layer of LT-OCA.
