Abstract: A head mounted display (HMD) device and method of manufacturing the same. The HMD includes a frame housing a micro-display to project display light, a lightguide configured to receive the display light from the micro-display, and a corrective layer having a world-side surface coupled to the eye-side surface of the lightguide. The lightguide is further configured to have a world-side surface with a radius of curvature based on an ophthalmic corrective prescription and an eye-side surface having an outcoupler feature formed thereon such that the coupled lightguide and corrective layer form a lens configured to fit within the frame.
