Abstract: A head-mounted device may have optical modules that present images to a user's left and right eyes. Each optical module may have a lens support structure that supports a display and a fixed lens. Vision correction lenses may be removably coupled to the fixed lenses to help customize the head-mounted device to the vision of a particular user. A user may view images on the displays through the removable and fixed lenses from eye boxes. The optical modules may include infrared light sources that supply infrared light to the eye boxes and infrared light sensors such as infrared cameras for gaze tracking and authentication. The lenses may have optical surfaces covered with coating that enhance optical performance and may have edge surfaces that are provided with structures to help reduce stray light reflections. The lenses may be configured to pass visible and infrared light.

Abstract: A lens module in a head-mounted device may include a fluid-filled chamber, a semi-rigid lens element that at least partially defines the fluid-filled chamber, and at least one actuator configured to selectively bend the semi-rigid lens element. The semi-rigid lens element may become rigid along a first axis when the lens element is curved along a second axis perpendicular to the first axis. Six actuators that are evenly distributed around the periphery of the semi-rigid lens element may be used to control the curvature of the semi-rigid lens element. The semi-rigid lens element may initially be planar or non-planar. For example, the semi-rigid lens element may initially have a spherically convex surface and a spherically concave surface. A tunable spherical lens may be incorporated into the lens module to offset a parasitic spherical lens power from the semi-rigid lens element.

Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.

Abstract: An electronic device may include a display with a concave surface. A linear polarizer may be formed on the concave surface. A quarter wave plate may receive light from the linear polarizer. A catadioptric lens may have first and second lens elements. The first lens element may have first and second opposing surfaces. The second lens element may have opposing third and fourth surfaces. The first surface may be convex and may face the display. The fourth surface may be concave. The second surface may be concave. The third surface may be convex and may match the second surface. An additional quarter wave plate may be formed as a coating on the third surface. A partially reflective coating may be formed on the first surface. A reflective polarizer may be formed as a coating on the fourth surface. An additional polarizer may be formed on the reflective polarizer.

Abstract: An electronic device display and a display cover layer may be coupled to a housing. The display may have an array of pixels that are configured to emit light. One or more light redirecting elements may be incorporated into the electronic device that redirect and thereby change the direction of light rays emitted from peripheral pixels in the display. The light redirecting elements may be used to enlarge the effective size of the display, to create images on sidewall surfaces of the display cover layer, and/or to create diffuse glowing areas around the periphery of the device. Light redirecting elements may be formed as integral portions of a display cover layer, as laminated optical films on a display cover layer, or as coating layers on a display cover layer. Afocal optical systems may be formed by placing first and second light redirecting elements on opposing first and second sides of a display cover layer.

Abstract: An electronic device such as a head-mounted device may have a head-mounted housing that separates an exterior region from an interior region. Optical modules may be mounted in alignment with openings in the rear of the housing. Each optical module may have a display and a lens through which an image on the display may be viewed. To protect the optical modules, the head-mounted device may be provided with photochromic lenses that darken and block sunlight when exposed to ultraviolet light and/or may be provided with shutters, lens caps, protective movable housing portions, tunable lenses that can be adjusted to defocus sunlight, and/or other protective structures for protecting lenses from scratches and for protecting displays from damage due to excessive sunlight exposure. Electrically adjustable protective structures may be operated based on sensor measurements.
