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

1. A spectacle lens comprising:

a front surface;

a back surface;

a peripheral edge; and

a vision correcting area having a refractive error correction that uses ambient light for correcting a refractive error of an eye, wherein at least a portion of the refractive error correction is based on a lens prescription determined by a wave front analysis of a wearer'"'"'s eye, wherein the vision correcting area corrects non-conventional refractive error to provide at least a part of the wearer'"'"'s vision correction, wherein the peripheral edge is capable of being modified to fit within an eyeglass frame, wherein the non-conventional refractive error is a refractive error other than myopia, hyperopia, presbyopia or regular astigmatism, and wherein correction of the non-conventional refractive error is provided by localized changes in refractive power of the lens.

2. The lens of claim 1 wherein the vision correcting area corrects for conventional refractive error, wherein the conventional refractive error is at least one of myopia, hyperopia, presbyopia or regular astigmatism.

3. The lens of claim 1 wherein the vision correcting area corrects for an aberration of the lens.

4. The lens of claim 1 wherein the lens comprises a material having a variable index of refraction.

5. The lens of claim 1 wherein the lens comprises a material having a modifiable index of refraction.

6. The lens of claim 1 wherein the back surface is concave.

7. The lens of claim 1 wherein the lens is capable of correcting non-conventional refractive error caused by one of an aberration, irregular astigmatism, and ocular layer irregularities.

8. The lens of claim 1 wherein the lens provides a prismatic power.

9. The lens of claim 1 wherein the lens has a chromic characteristic.

10. The lens of claim 1 wherein the lens corrects the wearer'"'"'s vision to better than 20/20.

11. The lens of claim 1 wherein the lens corrects the wearer'"'"'s vision to better than 20/10.

12. The lens of claim 1 wherein the non-conventional refractive error correction is different in different regions of the vision correcting area.

13. A spectacle lens comprising:

a front surface;

a back surface;

a peripheral edge; and

a vision correcting area that provides at least two different regions of refractive error correction that uses ambient light for correcting a refractive error of an eye, wherein the refractive error correction of a first region utilizes a prescription determined in part from a wave front analysis of a wearer'"'"'s eye and corrects for both non-conventional refractive error and conventional refractive error to provide for the highest level of vision correction for the wearer within the vision correcting area and wherein the refractive error correction of a second region corrects for refractive error that provides a lesser level of vision correction for the wearer than the refractive error correction of the first region, wherein the conventional refractive error is at least one of myopia, hyperopia, presbyopia or regular astigmatism and the non-conventional refractive error is a refractive error other than myopia, hyperopia, presbyopia or regular astigmatism.

14. The lens of claim 13 wherein the vision correcting area corrects for one of distance, intermediate, or near vision of the wearer.

15. The lens of claim 13 wherein the vision correcting area corrects for an aberration of the lens.

19. The lens of claim 13 wherein the lens provides a prismatic power.

20. The lens of claim 13 wherein the lens has a chromic characteristic.

21. The lens of claim 13 wherein correction of non-conventional refractive error is provided by localized changes in a refractive power of the lens.

22. The lens of claim 13 wherein the lens corrects the wearer'"'"'s vision to better than 20/20.

25. The lens of claim 13 wherein the vision correcting area provides at least two regions for the correction of non-conventional refractive error in different areas of the lens.

29. The spectacle lens of claim 13 wherein the non-conventional refractive error is an aberration of the ocular system.

26. A lens comprising:
