  • Patent number: 11360313
    Abstract: Systems and methods for auto-calibrating a virtual reality (VR) or augmented reality (AR) head-mounted display to a given user with a refractive condition without adding corrective lenses to optical elements of the head-mounted display and without requiring subjective refraction procedures. An autorefractor assembly of the head-mounted display, or a separate autorefractor headset, measures refractive error and communicates the measurements to a control system of the head-mounted display. Based on the refractive error measurements, the head-mounted display can adjust adaptive lenses and other adaptive optics to modify transmitted images; can make compensating adjustments to images displayed by a stereoscopic display device of the head-mounted display; or can make both types of adjustment. These automatic calibrations correct displayed images to compensate for refractive aberration in one or both eyes of the user.
