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.
