US Patent 9588396 Laser patterning of conductive films for electro-active lenses

Systems and methods for manufacturing electro-active lenses including a peripheral edge, a discrete electro-active region, and at least two substrates. The at least two substrates include a layer of a transparent conductive material, that is laser cut to isolate regions required for establishing an electrical connection between the peripheral edge of the lens, from regions not required for establishing an electrical connection. Isolating the regions of the transparent conductive material required for establishing an electrical connection may include cutting patterns around an electrode of each of the substrates. The regions not required for establishing an electrical connection may be further cut into sections, which may be substantially band-shaped.
