1. A head-mounted device configured to generate images viewable by a user having an eye with refractive errors that is located at an eye position, comprising:
a display configured to display the images;
a lens through which the images are viewable;
a sensor having a waveguide configured to receive light from a light source and to provide the received light towards the eye position and having a camera configured to receive a reflected version of the light from the eye position, wherein the waveguide, the lens, and the display overlap the eye position along a same direction in front of the eye position;
a positioner coupled to the display; and
control circuitry configured to measure the refractive errors with the sensor and configured to adjust the positioner based on the measured refractive errors.
