Abstract
An electro-active spectacle lens is disclosed. The disclosed lens includes a first lens optic. The disclosed lens also includes a first electro-active zone positioned in a cooperative relationship with the first lens optic. In certain embodiments, the electro-active lens includes a range finder positioned in a cooperative relationship with the electro-active lens.
Claims69
An electro-active spectacle comprising:
- an electro-active lens;
- a frame holding the electro-active lens;
- a viewing change detector coupled to the electro-active lens;
- and
- a manual switch in communication with the viewing change detector,
- wherein the manual switch is adapted to override the viewing change detector to allow a selective manual focus of the electro-active lens.
An electro-active spectacle comprising:
- an electro-active lens;
- a frame holding the electro-active lens;
- and
- a viewing change detector coupled to the electro-active lens and adapted for a change in head position of a wearer of the electro-active spectacle, the viewing change detector including
- a first detector adapted to detect the head position change, and
- a second detector adapted to override the first detector.
An electro-active programmable spectacle, comprising:
- an electro-active lens;
- and
- a time delay controller configured to adjust a voltage applied to the electro-active lens according to a programmed time adjustment.
A method for adjusting a focal length of an electro-active lens, comprising:
- changing the focal length of at least a portion of the electro-active lens;
- recognizing a change of head position of a wearer of the electro-active lens;
- and
- overriding the focal length change in response to the head position change.
A system, comprising:
- an electro-active lens;
- a frame configured to hold the electro-active lens;
- and
- a programmable controller coupled to the electro-active lens and configured to adjust a voltage applied to the electro-active lens according to a programmed time adjustment.
An electro-active lens focusing system, comprising:
- an electro-active lens;
- a range finder housed within the perimeter of the electro-active lens;
- a controller coupled to the electro-active lens and configured to adjust a voltage applied to the electro-active lens according to a signal from the range finder;
- and
- a power source coupled to the controller.
An electro-active spectacle, comprising:
- an electro-active lens;
- and
- a controller coupled to the electro-active lens and configured to adjust a focal length of the lens according to an adjustable time delay, the delay being adjustable for a wearer of the spectacle.
