1. An ocular imaging system comprising:
a substrate having a meta-surface formed thereon, the meta-surface comprising an imaging zone having a first plurality of meta-atoms, wherein the meta-surface is to be positioned to image a portion of an eye;
a light source to illuminate at least the portion of the eye; and
an array of photodetectors located at a focal surface of the meta-surface to detect an image of the portion of the eye that is formed by the imaging zone.
