ABSTRACT:
An electrochromic device for use in the field of optical lenses. The device includes a substrate having an expanse and an edge region. A first electrode layer is coated on the expanse and extends substantially across the expanse and into the edge region. An electrochromic layer is coated on the first electrode so that the first electrode layer physically isolates the electrochromic layer from the substrate. A second electrode layer is coated on the electrochromic layer, so that the electrochromic layer physically isolates the second electrode layer from the first electrode layer. A first contact is electrically connected to the first electrode layer. An isolative barrier is coated on the first electrode layer in the edge region. A second contact is electrically connected to the second electrode layer. Alternatively, an isolative channel is formed in the second electrode layer to electrically isolate the first electrode layer from the second electrode layer.
