ADAPTIVELY FOCUSING EXTRA-OCULAR VISION PROSTHESES

摘要

A vision prosthesis (fig. 1 element 13) includes an actuator (fig. 1 element 14) in communication with an extra-ocular lens (fig. 1 element 12). The actuator providing a focusing stimulus to vary a focal length of the lens. A rangefinder ( fig. 1 element 18) estimates a range to an object and provides the range estimate to a controller (fig. 1 element 16).The controller causes the actuator to generate the focusing stimulus on the basis of the range estimate.
