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 method of programming an electro-active spectacle comprising:

programming a prescription based on a conventional refractive error into a controller that controls an electro-active lens;

measuring a non-conventional refractive error of a patient'"'"'s eye using either an autorefractor or a wavefront analyzer, while the patient is looking through the electro-active lens, and while the electro-active lens is controlled to correct for the prescription;

refining of the prescription by;

accounting for the non-conventional refractive error measured while the patient is looking through the electro-active lens while the electro-active lens is controlled to correct for the prescription;

programming the electro-active spectacle with the refined prescription.

2. The method of claim 1, further comprising dispensing the electro-active spectacle to the patient.

3. The method of claim 1, further comprising determining the conventional refractive error programmed into the controller that controls the electro-active lens by measuring the conventional refractive error of the patient'"'"'s eye using a refractor.

4. The method of claim 3, wherein the refractor used to measure the conventional refractive error is a conventional refractor, an electro-active refractor, or an autorefractor.

5. The method of claim 1, further comprising:

measuring a non-conventional refractive error of a patient'"'"'s eye using either an autorefractor or a wavefront analyzer, while the patient is looking through the electro-active lens, and while the electro-active lens is controlled to correct for the refined prescription;

further refining of the refined prescription by;

accounting for the non-conventional refractive error measured while the patient is looking through the electro-active lens, while the electro-active lens is controlled to correct for the refined prescription.

6. The method of claim 1, comprising further refining the prescription via the patient using a control unit.

7. The method of claim 1, comprising further refining the prescription via an eye care professional using a control unit.

8. The method of claim 1, wherein the controller is read-only.

9. The method of claim 1, wherein the controller is reprogrammable.

10. The method of claim 1, wherein the controller is an ASIC.

11. The method of claim 1, wherein the controller is an FPGA.

12. The method of claim 1, wherein the refined prescription programmed into the electro-active spectacle improves the patient'"'"'s visual acuity to better than 20/20.

13. The method of claim 1, wherein the non-conventional refractive error is due to an irregular astigmatism.

14. The method of claim 1, wherein the non-conventional refractive error is due to ocular refractive irregularities.

15. The method of claim 1, wherein the non-conventional refractive error is due to aqueous irregularities.
