Eyeglass devices and related methods

Abstract

Eyeglass devices may include 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, and an eye-tracking element mounted to the frame. The varifocal optical element may include 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. The eye-tracking element may be configured to track at least a gaze direction of the user's eyes, and the varifocal optical element may be configured to change, based on information from the eye-tracking element, in at least one optical property including a focal distance. Various other devices, systems, and methods are also disclosed.
