Abstract
A lens system may include a lens having a liquid crystal layer and a driving electrode array disposed on a first side of the liquid crystal layer, the driving electrode array including a plurality of driving zones that are independently operable. The plurality of driving zones may each include a plurality of driving electrodes consecutively arranged along a radial direction extending from a central region of the lens. The lens system may include a controller that is configured to independently operate each of the plurality of driving zones via a separate plurality of bus lines coupled to each of the plurality of driving zones. The controller may be configured to operate at least one of the driving zones based on a gaze direction of the user. Various other devices, systems, and methods are also disclosed.
