Abstract
An apparatus for eye sight enhancement includes a lens having a first mode with a first optical power and a second mode with a second optical power, an actuator device adapted to vary a mode of the lens from the first mode to the second mode and from the second mode to the first mode, a fixing device adapted to fix the lens in a mounting position, a sensor device adapted to determine a focusing distance, and a processor adapted to control an operation of the actuator device depending on the focusing distance.
