Claims20
A method comprising:
- receiving, via a first side of a partially reflective and partially transmissive optical element, image light produced by a display of a wearable head device, the image light associated with a focal distance;
- transmitting, via a second side of the partially reflective and partially transmissive optical element, the image light to an eye of a user of the wearable head device, wherein the second side of the partially reflective and partially transmissive optical element is different from the first side of the partially reflective and partially transmissive optical element;
- receiving eye-image light from the eye via the second side of the partially reflective and partially transmissive optical element, the eye-image light comprising image light reflected in the eye;
- and
- adjusting the focal distance of the image light based on a sharpness of the eye-image light.

A wearable head device comprising:
- a display;
- and
- a partially reflective and partially transmissive optical element comprising a first side and a second side;
- wherein the partially reflective and partially transmissive optical element is configured to:
- receive, via the first side, image light produced by the display, the image light associated with a focal distance,
- transmit, via the second side, the image light to an eye of a user of the wearable head device, and
- receive, via the second side, eye-image light from the eye, the eye-image light comprising image light reflected in the eye;
- and
- wherein the display is configured to adjust the focal distance of the image light based on a sharpness of the eye-image light.
