Eyeglass manufacturing method using variable index layer
View Patent ↗An eyeglass lens and manufacturing method using a variable refractive index material, such as epoxy. In one embodiment, a method of making an eyeglass lens includes: imaging a patient's eye to determine a wavefront prescription for the patient; and curing the lens based on the wavefront prescription such that the wavefront guided lens corrects for aberrations over the lens for a plurality of gazing angles of the patient.
1. An eyeglass lens comprising a radiation curable layer having a varying index of refraction wherein said layer is cured based on one or more wavefront measurements and corrects for aberrations over the lens for a plurality of gazing angles of a patient.
2. The lens of claim 1 comprising a supervision zone that corrects for higher order aberrations for said plurality of gazing angles, wherein a remainder of the lens comprises a normal vision zone that is cured to correct only lower order aberrations.
3. The lens of claim 2 further comprising a transitions zone located between the supervision zone and the normal vision zone.
4. The lens of claim 2 wherein the supervision zone comprises a plurality of supervision islands located on the lens.
5. The lens of claim 1 further comprising two outer lenses and a radiation curable epoxy layer sandwiched between the two outer lenses.
6. A method of making a wavefront guided eyeglass lens which comprises:
imaging a patient's eye to determine a wavefront prescription for the patient; and
curing the lens based on the wavefront prescription such that the wavefront guided lens corrects for aberrations over the lens for a plurality of gazing angles of the patient.
7. The method of claim 6 wherein the lens design is further based on a vertex distance of the patient.
8. The method of claim 6 wherein the lens design is further based on the curve of the lens.
9. The method of claim 6 wherein the lens contains a variable index of refraction layer.
10. The method of claim 9 wherein the variable index of refraction layer is photo-induced.
11. A wavefront corrected lens comprising a base lens and a layer having a varying index of refraction wherein the wavefront corrected lens is designed using at least a predetermined wavefront measurement of a patient made on the patient's optical axis and the curvature of the base lens wherein the wavefront correction lens corrects low order and high order aberrations for a plurality of gazing angles of the patient.
12. The lens of claim 11 comprising a supervision zone that corrects for higher order aberrations for said plurality of gazing angles, wherein a remainder of the lens comprises a normal vision zone that is cured to correct only lower order aberrations.
13. The lens of claim 12 further comprising a transitions zone located between the supervision zone and the normal vision zone.
14. The lens of claim 12 wherein the supervision zone comprises a plurality of supervision islands located on the lens.
15. The lens of claim 11 further comprising two lens blanks and a radiation curable epoxy layer sandwiched between the lens blanks.
16. The lens of claim 11 wherein the at least one transition zone is configured to provide a smooth transition between a first vision zone configured to correct at least part of the plurality of different aberrations of the patient's eye for a first gazing angle and a second vision zone is configured to correct at least part of the plurality of different aberrations of the patient's eye for a second gazing angle.
