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.
Claims16
An electro-active lens comprising:
- an electro-active material of a substantially constant thickness;
- at least one alignment layer to align molecules of the electro-active material;
- a plurality of conductive electrodes arranged in a grid or array comprising a plurality of elements, wherein each grid or array element is an electrode, wherein each electrode is isolated from other electrodes by an insulating material;
- and
- wherein the electro-active lens is capable of being edged without destroying or removing material or components needed for the electro-active material to function properly.
2 more elements
An electro-active lens comprising:
- at least one layer of electro-active material having substantially constant thickness;
- at least one alignment layer to align molecules of the electro-active material;
- at least one grid or array of conductive electrodes in electrical contact with the at least one layer of electro-active material, wherein each grid or array element is an electrode and wherein the optical power of the electro-active lens is varied by altering an applied voltage from a power source to individual electrodes of the grid or array, each electrode is isolated from at least one other electrode by an insulating material;
- and
- wherein the electro-active lens is capable of being edged without destroying or removing material or components needed for the electro-active material to function properly.

An ophthalmic electro-active lens comprising:
- an electro-active material of a substantially constant thickness;
- at least one alignment layer to align molecules of the electro-active material;
- and
- a plurality of conductive electrodes arranged in a grid or array comprising a plurality of elements, wherein each grid or array element is an electrode, wherein each electrode is isolated from other electrodes by an insulating material,
- wherein the electro-active material is at least partially disposed above a pupil of a wearer's eye when the ophthalmic electro-active lens is in an as-worn position, and
- wherein the ophthalmic electro-active lens is capable of being edged without destroying or removing material or components needed for the electro-active material to function properly.
