    Abstract: Eyeglass devices may include a frame shaped and sized to be worn by a user at least partially in front of the user's eyes, a varifocal optical element mounted to the frame, and an eye-tracking element mounted to the frame. The varifocal optical element may include a substantially transparent actuator positioned at least partially within an optical aperture of the varifocal optical element and configured to alter a shape of the varifocal optical element upon actuation. The eye-tracking element may be configured to track at least a gaze direction of the user's eyes, and the varifocal optical element may be configured to change, based on information from the eye-tracking element, in at least one optical property including a focal distance. Various other devices, systems, and methods are also disclosed.

    Abstract: An optical assembly for an eye-tracking camera includes an aperture stop, a first optical surface, and a second optical surface. The optical assembly is configured to receive non-visible light reflected or scattered by an eye and to direct the non-visible light to an image sensor along an optical path, where the non-visible light is received from an optical combiner of an eye-tracking system. The first optical surface is disposed on the optical path and is configured to correct for field-independent optical aberrations induced by the optical combiner. The second optical surface is disposed on the optical path and is configured to correct for field-dependent optical aberrations induced by the optical combiner.

    Abstract: An apparatus comprising (1) a conoscope configured to receive an image emitted by a display device through a corrective lens, (2) a variable compensation element coupled to the conoscope, wherein the variable compensation element is capable of selectively modifying the image emitted by the display device to compensate for an optical effect imparted by the corrective lens on the image, and (3) a controller coupled to the variable compensation element, wherein the controller (1) receives a compensation parameter representative of the optical effect imparted by the corrective lens on the image, (2) selects, based at least in part on the compensation parameter, a feature of the variable compensation element that compensates for the optical effect, and (3) causing the feature of the variable compensation element to be applied to the image. Various other apparatuses, systems, and methods are also disclosed.

    Abstract: A backlight device includes a first surface and a second surface that is opposite to the first surface. The backlight device is configured to emit light in a first optical band through the second surface toward a display panel of a head-mounted display (HMD). The display panel is configured to convert the light from the backlight device to image light. The backlight device is transparent to light in a second optical band that is different than the first optical band. An eye tracking system illuminates an eyebox with light in the second optical band. A camera assembly positioned adjacent to the first surface of the backlight device. The camera assembly is configured to capture images of the eye in the second optical band through the backlight device, the display panel. The eye tracking system determines eye tracking information based at least in part on the captured images.
