Abstract

A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides Correction for non-conventional refractive error to provide at least a part of the Wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.

Claims (24)

1. Electronic eyewear comprising:

an electronic component;

an eyeglass frame housing said electronic component; and

a lens including an electronic region of electronically changeable focus,

wherein said electronic region includes electro-active material that changes index with the application of electricity,

wherein said region changes focus as the index of said electro-active material changes, and

wherein said lens further comprises a progressive addition power region.

2. The eyewear of claim 1 , further comprising a controller.

3. The eyewear of claim 1 , further comprising a battery.

4. The eyewear of claim 1 , further comprising a fuel cell.

5. The eyewear of claim 1 , further comprising a tilt switch.

6. The eyewear of claim 1 , further comprising an accelerometer.

7. The eyewear of claim 1 , further comprising a range finder.

8. The eyewear of claim 1 , wherein said lens comprises a diffractive region.

9. The eyewear of claim 1 , wherein said lens comprises a refractive region.

10. The eyewear of claim 1 , wherein said lens comprises a pixilated region.

11. The eyewear of claim 1 , wherein said electro-active material is liquid crystal.

12. The eyewear of claim 1 , wherein said electro-active material is polymer liquid crystal.

13. The eyewear of claim 1 , wherein said electro-active material is polymer dispersed liquid crystal.

14. The eyewear of claim 1 , wherein said electro-active material is polymer stabilized liquid crystal.

15. The eyewear of claim 1 , wherein said lens comprises a photochromic material.

16. The eyewear of claim 1 , wherein said lens comprises an electro-chromic material.

17. The eyewear of claim 1 , wherein said lens is fabricated from an electro-active semifinished lens blank.

18. The eyewear of claim 1 , wherein said frame houses an electrical power component, and an electrical connecting component connecting said electrical power component to said lens.
