Systems, articles, and methods for integrating holographic optical elements with eyeglass lenses
First Claim
1. A method of manufacturing a lens for use in a wearable heads-up display, the method comprising:
- providing a photopolymer film;
recording a hologram into the photopolymer film while the photopolymer film is planar;
applying a curvature to the photopolymer film;
molding a lens-forming fluid to produce a first portion of the lens having the photopolymer film embedded therein;
providing a second portion of the lens;
adhering a surface of the second portion of the lens and a first surface of the first portion of the lens together by a first portion of optical adhesive; and
applying an eyeglass prescription curvature to the lens, wherein recording a hologram into the photopolymer film includes recording a hologram that compensates for both an optical effect of the prescription curvature of the lens and an optical effect of the curvature applied to the photopolymer film.

Abstract
Systems, articles, and methods that integrate photopolymer film with eyeglass lenses are described. One or more hologram(s) may be recorded into/onto the photopolymer film to enable the lens to be used as a transparent holographic combiner in a wearable heads-up display employing an image source, such as a microdisplay or a scanning laser projector. The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lens around the photopolymer film; sandwiching photopolymer film in between two portions of a lens; applying photopolymer film to a concave surface of a lens; and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens. Respective lenses manufactured/adapted by each of these processes are also described.
