1. A head-mounted display system configured to project light to an eye of a user to display augmented reality image content in a vision field of the user, the head-mounted display system comprising:
a frame configured to be supported on a head of the user;
an image projector configured to project images comprising image content;
at least one camera; and
an eyepiece supported by the frame, the eyepiece configured to direct the images into the eye of the user to display the image content in the vision field of the user, at least a portion of the eyepiece being transparent to enable the user to view an environment in front of the user while viewing the displayed image content, the eyepiece comprising:
a waveguide;
at least one in-coupling optical element configured such that light incident thereon is coupled into the waveguide and guided therein, wherein the incident light includes light reflected off a surface of the eye, wherein the at least one in-coupling optical element comprises a diffractive optical element having a coupling area for coupling the incident light into the waveguide, wherein the coupling area is a pinhole size coupling area having an average thickness in a range from 0.1 to 3 millimeters across; and
at least one out-coupling optical element configured to couple at least a portion of the light guided within the waveguide out of the waveguide to be captured by the at least one camera, wherein the at least one camera generates at least one image of the eye based on the captured light.
