1. A head mounted display system for displaying image content to a user, the display system comprising:
at least one display configured to be worn by a user to present virtual content to first and second eyes of a user;
a first inward facing camera configured to image the first eye of the user;
a second inward facing camera configured to image the second eye of the user; and
processing electronics in communication with the first and second inward-facing cameras and the at least one display, the processing electronics configured to:
present virtual content to the user on the at least one display;
using the first inward-facing camera, determine that the first eye is at least partially closed;
using the second inward-facing camera, determine that the second eye is at least partially closed;
determine a gaze direction of the first and second eyes;
determine a vergence of the first and second eyes; and
based on (i) the determination that the first and second eyes of the user are at least partially closed, (ii) the gaze direction of the first and second eyes, and (iii) the vergence of the first and second eyes, alter a state of the head mounted display system so as to modify the virtual content presented to the user, a manner in which virtual content is presented to the user, a performance feature of the head mounted display system apparent to the user, or any combination thereof.
