Abstract
An auto-focus head-mounted display (HMD) dynamically generates aberration-adjusted images based on measured accommodation of user's eye(s). 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. The aberration-adjusted image corrects the aberrations of the HMD and 'accounts' for the aberrations of the eye so that the resulting retinal image is free of optical aberrations due to the HMD but preserves correct eye optical aberrations that are correlated with a current accommodative state of the eye.
