1. An apparatus, comprising:
an adjustable lens assembly, comprising:
a first adjustable lens comprising a first deformable optical element;
a second adjustable lens comprising a second deformable optical element;
a first actuator coupled to the first deformable optical element such that mechanical action of the first actuator applies a force to the first deformable optical element; and
a second actuator coupled to the second deformable optical element such that mechanical action of the second actuator applies a force to the second deformable optical element;
a display element situated between the first adjustable lens and the second adjustable lens;
a sensor positioned to measure a state of at least one of the first or second adjustable lens; and
a controller configured to actuate at least one of the first or second actuators via closed-loop control based on data received from the sensor.
