Abstract: An electronic device may include a display and a lens module through which the display is viewable. The lens module may include a tunable lens with an adjustable spherical power, cylindrical axis, and/or cylindrical power. To tune the tunable lens to compensate for a viewer's eyesight, the display may present at least one target. The optical power of the tunable lens may be set based on the point of gaze relative to the at least one target. Multiple targets with associated optical powers may be presented and the optical power of the tunable lens may be set depending on which target is aligned with the point of gaze. The display may present an image through a masking layer with a ring of pinhole pairs. The electronic device may include an input device that receives user input regarding a perceived image associated with the display and the masking layer.

Abstract: An electronic device may include a lens module with a tunable lens. The tunable lens may be operable in multiple modes such as a normal mode, a presbyopia-mitigation mode, a near-focus mode, and a negative power boost mode. During operation, the electronic device may gather data and adjust the tunable lens based on the gathered data. The tunable lens may be switched from the normal mode to the presbyopia-mitigation mode in response to determining that a nearby object is being viewed through the lens module. The tunable lens may be switched from the normal mode to the negative power boost mode in response to ambient light levels being low and/or eye fatigue levels being high. The tunable lens may switch between modes over a transition period. An output device may notify the user when the tunable lens changes modes.
