Abstract
An electroactive lens, method, and pair of glasses are described. The electroactive lens forms a stack of at least three elements. A first transparent body is a first lens element having a first optical axis. A second transparent body is a second lens element having a second optical axis. At least one lens foil sandwiched between the first and second transparent body comprises a first and second transparent electrode, and a Fresnel lens and liquid crystalline material therebetween to define an optical device. The first and second transparent electrodes are electrically coupled to terminals and are configured to receive a voltage for operating the switchable lens. First and second conductive plug are positioned relative to the optical axis of the Fresnel lens such that radial lines extending from the optical axis to the first and second conductive plugs mutually enclose an angle of less than 120, 90, or 60 degrees.
