Abstract
Adjustable variable transmissivity (AVT) eyeglasses for patients. In one embodiment, the eyeglasses include: (1) a frame having earpieces coupled thereto, (2) liquid crystal lenses coupled to the frame and configured to assume a transmissivity in response to a lens control signal, (3) a light sensor coupled to the frame and configured to sense light in a field of view and produce a sensor signal in response thereto, (4) a light plug coupled to the frame and configured to define a field of view and (5) an electronic circuit coupled to the frame and configured to employ the sensor signal to generate the lens control signal.

Eyeglasses, comprising;
- a frame having earpieces coupled thereto;
- liquid crystal lenses coupled to the frame and configured to assume a transmissivity in response to a lens control signal;
- a light sensor coupled to the frame and configured to sense light in a field of view and produce a sensor signal in response thereto;
- a light plug coupled to the frame and configured to define a field of view;
- and
- an electronic circuit coupled to the frame and configured to employ the sensor signal to generate the lens control signal.
A method of manufacturing eyeglasses, comprising:
- forming a frame having earpieces coupled thereto;
- coupling liquid crystal lenses to the frame, the lenses configured to assume a transmissivity in response to a lens control signal;
- coupling a light sensor to the frame, the light sensor configured to sense light in a field of view and produce a sensor signal in response thereto;
- coupling a light plug to the frame, the light plug configured to define a field of view;
- and
- coupling an electronic circuit to the frame, the lenses and the light sensor, the electronic circuit configured to employ the sensor signal to generate the lens control signal.
Eyeglasses, comprising:
- a frame having earpieces rotatably coupled thereto;
- liquid crystal lenses coupled to the frame and configured to assume a transmissivity in response to a lens control voltage signal;
- a light sensor coupled to the frame and configured to sense light in a field of view forward of the eyeglasses and produce a sensor current signal in response thereto;
- a light plug coupled to the frame and configured to define a field of view relative to the lenses, the light plug having at least two apertures positionally arranged to define the field of view in a horizontal plane and in a vertical plane;
- and
- an electronic circuit coupled to the frame and configured to employ the sensor current signal to generate the lens control voltage signal.
