Abstract: In an example method for forming a variable optical viewing optics assembly (VOA) for a head mounted display, a prepolymer is deposited onto a substrate having a first optical element for the VOA. Further, a mold is applied to the prepolymer to conform the prepolymer to a curved surface of the mold on a first side of the prepolymer and to conform the prepolymer to a surface of the substrate on a second side of the prepolymer opposite the first side. Further, the prepolymer is exposed to actinic radiation sufficient to form a solid polymer from the prepolymer, such that the solid polymer forms an ophthalmic lens having a curved surface corresponding to the curved surface of the mold, and the substrate and the ophthalmic lens form an integrated optical component. The mold is released from the solid polymer, and the VOA is assembled using the integrated optical component.
