System, apparatus, and method for correcting vision using an electro-active lens
View Patent ↗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.
1. A lens, comprising:
a first region having a variable index of refraction;
a second region associated with unwanted astigmatism, wherein the first region reduces the unwanted astigmatism associated with the second region.
2. The lens of claim 1 , wherein the first region is electro-active.
3. The lens of claim 2 , wherein the first electro-active region comprises a multi-grid electro-active structure.
4. The lens of claim 2 , wherein the first region comprises pixels.
5. The lens of claim 1 , wherein the first region provides a neutralizing power compensation.
6. The lens of claim 5 , wherein the neutralizing power compensation is provided solely in areas of the lens where the unwanted astigmatism exists.
7. The lens of claim 1 , wherein the first region is positioned on a back of the lens.
8. The lens of claim 1 , wherein the first region is positioned on a front of the lens.
9. The lens of claim 1 , wherein the first region is positioned between a front and a back of the lens.
10. The lens of claim 1 , wherein the first region corrects for an aberration of a user's eye.
11. The lens of claim 10 , wherein the corrected aberration is an aberration other than myopia, hyperopia, and regular astigmatism.
12. The lens of claim 1 , wherein the lens corrects for at least one of myopia, hyperopia, and regular astigmatism.
13. The lens of claim 1 , wherein the first region and the second region provide a total lens power of the lens.
14. The lens of claim 1 , wherein the second region comprises a progressive addition region.
15. The lens of claim 1 , wherein the first region comprises polymer material.
16. The lens of claim 1 , wherein the first region corrects for an aberration of the lens.
