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.

Eyeglass devices and related methods

An actuator includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive layer disposed between and abutting the primary electrode and the secondary electrode, where a mechanical deformation of the electroactive layer is locally controllable over an area of the actuator. The mechanical deformation of the electroactive layer may be configured to generate compound curvature, e.g., in an optical element co-integrated with the actuator, without buckling the optical element.

Actuator for generating compound curvature

A device includes a first lens configured to provide a first optical power that is variable within a first optical power adjustment range at a first step resolution. The device also includes a second lens coupled with the first lens and including a deformable member that is deformable to vary an optical power of the second lens. The second lens is configured to provide a second optical power that is variable within a second optical power adjustment range at a second step resolution, the second step resolution being smaller than the first step resolution.
