Abstract
Techniques and mechanisms for providing an eye-mountable device including an accommodation actuator. In an embodiment, fabrication of the eye-mountable device includes sealing layers of enclosure material to form a lens enclosure comprising a pinch-off region where the layers of enclosure material physically contact one another. The accommodation actuator includes a liquid crystal layer disposed between the layers of enclosure material in a central region around which the pinch-off region extends. In another embodiment, electrodes are disposed in the central region each between the liquid crystal layer and a respective one of the layers of enclosure material. The liquid crystal layer isolates the electrodes from one another in the central region.
