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: The disclosure describes artificial reality (AR) systems and techniques that enable a change in focus of virtual image content without substantially changing magnification of real-world content. For example, an AR system includes a virtual image content output device, a first tunable lens on a real-world side of the virtual image content output device, a second tunable lens on an eye side of the virtual image content output device, and at least one compensating lens. The at least one compensating lens is configured to substantially eliminate magnification changes of real-world light between a real-world end of the optical system and an eye-side end of the optical system as a focal power of at least one of the first tunable lens or the second tunable lens changes.

Abstract: A device includes a light source configured to emit an image light. The device also includes an optical assembly configured to direct the image light to an eye-box of the device. The optical assembly includes a first optical element portion configured to focus a first portion of the image light propagating through the first optical element portion. The optical assembly also includes a second optical element portion configured to focus a second portion of the image light propagating through the second optical element portion. The second optical element portion includes a liquid crystal (“LC”) lens having an adjustable optical power.

Abstract: A display device includes a display panel having a first emission region and one or more second emission regions disposed adjacent to the first emission region. The display device includes a plurality of light emitters, arranged in the first emission region, corresponding to a first color gamut and a plurality of light emitters, arranged in the one or more second emission regions, corresponding to a second color gamut that is distinct from the first color gamut. A method for making a display device with a plurality of light emitters corresponding to a first color gamut in a first emission region and a plurality of light emitters corresponding to a second color gamut in a second emission region is also described.
