a frame;
a plurality of lenses disposed in the frame, wherein each of the plurality of lenses comprises:
a first common electrode;
a first liquid crystal material;
a first circular, variable focus liquid crystal Fresnel lens disposed along an optical axis and comprising a first set of electrodes arranged in a first concentric pattern and in electrical communication with the first liquid crystal material and the first common electrode;
a second common electrode;
a second liquid crystal material;
a first cylindrical lens disposed along the optical axis and comprising a second set of electrodes aligned with a first vertical meridian of the first cylindrical lens and in electrical communication with the second liquid crystal material and the second common electrode;
a third common electrode;
a third liquid crystal material;
a second cylindrical lens disposed along the optical axis and comprising a third set of electrodes oriented at a first angle with respect to the first vertical meridian and in electrical communication with the third liquid crystal material and the third common electrode;
a second circular, variable focus liquid crystal Fresnel lens disposed along the optical axis and having a fourth set of electrodes arranged in a second concentric pattern;
a third cylindrical lens disposed along the optical axis and comprising a fifth set of electrodes aligned with a second vertical meridian of the third cylindrical lens; and
a fourth cylindrical lens disposed along the optical axis and having a sixth set of electrodes oriented at a second angle with respect to the second vertical meridian.
