Abstract
An auto-focus head-mounted display (HMD) dynamically generates aberration-adjusted images based on the position and/or orientation of an eye of the user. An aberration-adjusted image is an image distorted to correct aberrations that would otherwise occur at a retina of the user due to image light passing through optics of the HMD that contains one or more optical imperfections. The aberration-adjusted image corrects the aberrations caused by these optical imperfections so that the resulting retinal image is free of optical aberrations due to the HMD while preserving correct eye optical aberrations that correlate with a current accommodative state of the eye.
