An electro-active spectacle lens is disclosed. The spectacle lens comprises a first substrate having a first outer region and first inner region, a first electrode layer disposed adjacent to the first inner region, the first electrode layer including an outer electrode region having a first conductivity and an inner electrode region having a second conductivity, the first conductivity being greater than the second conductivity, a second substrate having a second outer region and second inner region, a second electrode layer disposed adjacent to the second inner region, the second electrode layer having a third conductivity, and an electro-active cell disposed between the first electrode layer and the second electrode layer, the electro-active cell containing an electro-active material. The first outer region and second outer region are configurable for fitting the spectacle lens within a lens frame without altering the electro-active cell.
