1. An electrowetting optical device comprising:
a first electrode at least partially circumscribing a first optical window;
a second electrode at least partially circumscribing a second optical window, wherein the second optical window is aligned with the first optical window along an optical axis;
a central region defined by a projection of a footprint of the second optical window in a direction of the optical axis;
a first dielectric portion covering the second optical window and positioned within the central region, the first dielectric portion comprising a first thickness;
a second dielectric portion at least partially covering the second electrode and at least partially circumscribing the central region, the second dielectric portion comprising a second thickness that is greater than the first thickness; and
a first liquid and a second liquid disposed within a containment region, wherein an interface between the first liquid and the second liquid forms a lens.
