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. One such method comprises determining, by a refraction headset in operative communication with a near-to-eye head-mounted display, a wavefront map of an eye of a user based on comparing a shape of a wavefront associated with the eye to a reference wavefront; controlling, by an imaging system of the near-to-eye head-mounted display, a stereoscopic display device based on the wavefront map to modify image light representative of a desired image for display to the user; and transmitting, without the use of user-customized corrective eyewear, the modified image light from the stereoscopic display device through optical elements of the near-to-eye head-mounted display toward the eye of the user.

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. A method comprises projecting a grid onto an eye of a user using a light source of a head-mounted display worn by the user, capturing the grid as-reflected from the eye using a camera of the head-mounted display, determining a pattern of a reflection of the grid based on the grid as-reflected, generating an aberration map based on a difference between the pattern as-reflected and the grid as-projected, and determining a correction to apply to at least one viewing lens of the head-mounted display worn by the user based on the aberration map.

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.
