A head-mounted device may include a lens module with a least one adjustable lens. The head-mounted device may be wirelessly paired to an electronic device such as a cellular telephone, watch, laptop computer, etc. To correct for presbyopia, the optical power of adjustable lenses in a head-mounted device may be adjusted when the user is viewing a close object. To allow for intelligent adjustments of the adjustable lenses while minimizing power consumption in the head-mounted device, the head-mounted device may receive sensor data and/or focal point change instructions from a paired electronic device. The paired electronic device may detect a trigger, analyze the user's attention to the paired electronic device, and send focal point change instructions to the head-mounted device based on the obtained information.

An in-ear electronic device comprising: an enclosure having an enclosure wall that defines an interior chamber surrounding a transducer and an opening from the interior chamber to an ambient environment surrounding the enclosure; and an acoustic valve comprising a driven member coupled to a driving member having a lever and a shape memory alloy operable to cause the driven member to open and close the opening upon application of a current.

An electronic device may include a display module that generates image light and an optical system that redirects the light towards an eye box. The optical system may have first hologram structures that replicate the light over multiple output angles onto second hologram structures. The second hologram structures may focus the replicated light onto the eye box. If desired, the device may include an image sensor. The first and second hologram structures may include transmission and/or reflection holograms. The optical system may redirect a first portion of the light to the eye box and a second portion of the light to the sensor. The sensor may generate image data based on the second portion of the light. Control circuitry may compensate for distortions in the first portion of the light by performing feedback adjustments to the display module based on distortions in the image data.
