1. A display system comprising:
an eye-tracking camera;
a display;
non-transitory data storage configured to store a plurality of calibrations for the display, calibrations in the plurality of calibrations associated with respective calibration positions relative to the display; and
a hardware processor in communication with the eye-tracking camera, the display, and the non-transitory data storage, the hardware processor programmed to:
determine, based on information from the eye-tracking camera, an eye position, relative to the display, of the user of the display;
access, based at least partly on the determined eye position, one or more of the plurality of calibrations;
calculate, based at least in part on the one or more of the plurality of calibrations, a correction to apply to the display to at least partially correct for an imperfection in the display; and
apply the correction to the display,
wherein the calibration in the plurality of calibrations corrects for a spatial imperfection of the display.
