  • Eyeglasses with controllable refracting power
    Patent number: 5182585
    Abstract: Eyeglasses equipped with liquid lenses having adjustable refractive power that depends on the amount of liquid forced into each lens. An electrically powered pump and an electronic controller regulate the liquid input to the lenses in response to a signal determined by the focal length required for viewing a given object in the field of vision. This focal length is determined by the use of a rangefinder mounted on the frame of the eyeglasses. The system is programmed for automatic response tailored to the specific eyesight of the wearer.
