Abstract

A system in accord with the present invention includes a first optical lens having a first outer surface, a second outer surface, and an outer perimeter, an electro-active refractive matrix; and a conductor coupled to the electro-active matrix. An alternative system in accord with the present invention includes a frame, the frame having a lens support and a temple region; an optical lens coupled to the lens support, the optical lens including an electro-active refractive matrix; a controller coupled to the electro-active refractive matrix; and a range finder coupled to the controller. The present invention also includes a method of assembling an optical lens system that comprises placing an electro-active refractive matrix into a cavity of a first optical lens; and covering at least a portion of the electro-active refractive matrix with a second optical lens.

Claims

1. An electro-active spectacle lens with a peripheral edge, comprising:

an electro-active element spaced from the peripheral edge, wherein said electro-active element has two surfaces and contains an electro-active material between said two surfaces for altering the optical power of the lens, wherein in the absence of electrical power the electro-active element does not alter the optical power of the lens when looking through the lens, and wherein when electrical power is applied the lens simultaneously provides at least two different optical powers when looking through the lens, and wherein an optical power blending transition occurs between the two different optical powers.

2. The electro-active spectacle lens of claim 1 comprising material external to the electro-active element, wherein a portion of the material external to the electro-active element is coated with material for minimizing the appearance of the electro-active element.

3. The electro-active spectacle lens of claim 1, wherein said electro-active element is located within a refractive optical element.

4. The electro-active spectacle lens of claim 1, wherein said electro-active element comprises an electrical conductor.

5. The electro-active spectacle lens of claim 1, wherein said electro-active element comprises electrodes.

6. The electro-active spectacle lens of claim 5, wherein one of said electrodes is a patterned electrode.

7. The electro-active spectacle lens of claim 5, wherein at least one electrode is spaced apart from any non-electro-active refractive element of said lens.

8. The electro-active spectacle lens of claim 5, wherein said electrodes are arranged substantially concentrically.

9. The electro-active spectacle lens of claim 1, wherein the lens is configurable to fit within a spectacle frame by removing material from the peripheral edge without altering focal properties of the electro-active element.

10. The electro-active spectacle lens of claim 1, wherein said electro-active element is adapted for providing diffraction.

11. The electro-active spectacle lens of claim 1, wherein said electro-active element is adapted for providing refraction.

12. The electro-active spectacle lens of claim 1, wherein said two surfaces of said electro-active element are substantially parallel.

21. The electro-active spectacle lens of claim 12, wherein said two surfaces of said electro-active element are substantially flat.

22. The electro-active spectacle lens of claim 12, wherein said two surfaces of said electro-active element are substantially curved.

14. An electro-active spectacle lens with a peripheral edge, comprising:

an electro-active element having at least a first region and a second region different from the first region, wherein the lens simultaneously provides at least a first optical power and a second different optical power when looking through the lens, wherein the first optical power is provided by at least the first region and the second optical power is provided by at least the second region, wherein said electro-active element is spaced from the peripheral edge.

15. The electro-active spectacle lens of claim 14, wherein said electro-active element further comprises a third region for providing a third different optical power when looking though the lens.

16. The electro-active spectacle lens of claim 14 or 15, having a gradual change in optical power from one region to another region.

17. The electro-active spectacle lens of claim 14 or 15, wherein said regions are concentric.

18. An electro-active spectacle lens with a peripheral edge, comprising:

an electro-active element simultaneously having both a region of constant optical power and a region of decreasing optical power towards the peripheral edge when looking through the lens.

19. The electro-active spectacle lens of claim 18, wherein the electro-active element is adapted for providing diffraction.

20. The electro-active spectacle lens of claim 18, wherein the electro-active element is adapted for providing refraction.
