1. An eyeglass device, comprising:
a frame shaped and sized to be worn by a user at least partially in front of the user's eyes;
a varifocal optical element mounted to the frame to be in a position in front of the user's eyes when the eyeglass device is worn by the user, wherein the varifocal optical element comprises a substantially transparent actuator positioned at least partially within an optical aperture of the varifocal optical element and configured to alter a shape of the varifocal optical element upon actuation;
an eye-tracking element mounted to the frame, wherein:
the eye-tracking element is configured to track at least a gaze direction of the user's eyes, and
the varifocal optical element is configured to change, based on information from the eye-tracking element, in at least one optical property including a focal distance; and
a manual input configured for the user to deactivate automatic changing of the at least one optical property by the varifocal optical element.
