Abstract
An eye-mountable device includes a flexible lens enclosure, anterior and posterior flexible conductive electrodes, and an accommodation actuator element. The flexible lens enclosure includes anterior and posterior layers that are sealed together. The anterior flexible conductive electrode is disposed within the flexible enclosure and across a center region of the flexible lens enclosure on a concave side of the anterior layer. The posterior flexible conductive electrode is disposed within the flexible enclosure and across the center region on a convex side of the posterior layer. The accommodation actuator element is disposed between the first and second flexible conductive electrodes. The anterior and posterior flexible conductive electrodes are transparent and electrically manipulate the accommodation actuator element.
