1. A contact lens comprising:
a biocompatible material suitable to be in contact with a human eye having an eye-side opposite an external side, wherein the eye-side is curved to fit a human eye;
a first substrate;
a light source configured to emit illumination light, wherein the light source is coupled to or disposed within the first substrate;
an optical system disposed to receive the illumination light from the light source and output the illumination light as an in-phase wavefront; and
a phase map disposed to receive the in-phase wavefront output from the optical system and to adjust a phase of the in-phase wavefront to form an image at a retina-distance in response to being illuminated by the in-phase wavefront output from the optical system, wherein the phase map includes a pre-recorded phase pattern disposed across a second substrate.
