Electro-active opthalmic lens having an optical power blending region
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 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.
