Abstract: An electrically activated lens filter (204) with an electro-optic portion (418) having a radially and circumferentially symmetric electric field gradient is disclosed. More particularly, embodiments of the lens filter (204) include an electro-optic portion (418) having one or more conductive plugs (512) arranged around a center region (514) such that an electric field within the electro-optic portion (418) varies from a maximum at an outer rim (408) to a minimum outside of the center region (514). The lens filter (204) may include a plurality of front electrodes (409) and rear electrodes (410) accessible in an axial direction for electrically activating front and rear transparent conductive layers (414, 416), respectively.
