1. A method of manufacturing a lens for use in a wearable heads-up display, the method comprising:
providing a photopolymer film;
providing a light directing element in contact with the photopolymer film while the photopolymer film is planar, the light directing element compensating for an optical effect of at least a curvature subsequently applied to the photopolymer film;
integrating the photopolymer film into the lens by at least one of:
molding the photopolymer film into the lens; or
adhering a surface of a first portion of the lens and a surface of a second portion of the lens to the photopolymer film.
