Abstract: An electrically activated lens filter with an electro-optic portion having a radially and circumferentially symmetric electric field gradient is disclosed. More particularly, embodiments of the lens filter include an electro-optic portion having one or more conductive plugs arranged around a center region such that an electric field within the electro-optic portion varies from a maximum at an outer rim to a minimum outside of the center region. The lens filter may include a plurality of front electrodes and rear electrodes accessible in an axial direction for electrically activating front and rear transparent conductive layers, respectively.
