PatentYogi Summary
This invention relates to positioning of an accommodation actuator of a smart contact lens in relation to activating electrodes and gaze sensor. The accommodation actuator is disposed in a central region of the smart contact lens in order to cover the foveal vision. The central region is defined by a pinch-off region that extends around a perimeter of the central region. The pinch-off region serves as a seal to hold the accommodation actuator within the central region. The peripheral region is located around a periphery of pinch-off region that includes contact lens material disposed and cured to aid in sealing of encapsulation layers with one another. This method of fabrication is advantageous compared to forming the accommodation actuator separately from other lens structures.
