1. A lens comprising:
a refractive lens layer including a lens surface having optical power, wherein the refractive lens layer includes an eyeward side and a backside to receive light from a display;
a reflective polarizer layer;
a linear polarizer layer disposed between the reflective polarizer layer and the refractive lens layer, wherein the linear polarizer layer includes surface waviness; and
a transparent optical layer disposed over the linear polarizer layer, wherein the transparent optical layer is a plastic film having a thickness of 300 microns or more that is disposed over the backside of the refractive lens layer and configured to smooth the surface waviness of the linear polarizer layer and wherein the transparent optical layer is disposed between the linear polarizer layer and the reflective polarizer layer.
