A substantially fully copolymerized UV blocking hydrogel lens demonstrating sufficient blocking of UV light to meet at least FDA Class II specifications for UV blocking formed from a reaction mixture comprising at least NVP and one other comonomer and a free-radical polymerizable, substituted or unsubstituted, Bis O-hydroxy benzophenone is provided herein. The method allows cellular wheels to be produced which have material wall thicknesses of 0. The invention further relates to seeds and plants produced by such crossing. The plurality of control gate electrodes include at least a first control gate electrode located in a first device level and a second control gate electrode located in a second device level.
