Abstract: An electronic device may have back-to-back displays. A user-facing display may have microlenses, tunable lens structures, holograms, lasers, and other structures for displaying images in multiple eye boxes while the electronic device is being worn on the head of a user. In some configurations, a switchable diffuser may be incorporated into the user-facing display. In one mode, the switchable diffuser allows microlenses of the pixels of the user-facing display to provide images to eye boxes in which images from the display are viewable. In another mode, the switchable diffuser diffuses light from the pixels so that the user-facing display may be used while the device is being held in the hand of the user.

Abstract: A pair of eyeglasses may include one or more adjustable lenses that are each configured to align with a respective one of a user's eyes. The adjustable lenses may each include electrically modulated optical material such as one or more liquid crystal cells. The liquid crystal cells may include arrays of electrodes that extend along one, two, three, four, or more than four directions. Control circuitry may apply control signals to the array of electrodes in each liquid crystal cell to produce a desired phase profile. Each lens may be foveated such that portions of the lens within the user's gaze exhibit a different phase profile than portions of the lens outside of the user's gaze. The control circuitry may adjust the location of the optically distinct area so that it remains aligned with the user's gaze.
