Ophthalmic lens media insert
This invention discloses methods and apparatus for providing an ophthalmic lens with media including an energy receptor. In some embodiments, the media includes an insert placed in a cavity formed to cast mold an ophthalmic lens from a reactive mixture.
1. A method of forming an ophthalmic lens, the method comprising:
depositing a conductive material capable of receiving energy via a radio wave on to a media;
depositing a reactive monomer mix into a first mold part;
positioning the media with the conductive material in contact with the reactive monomer mix;
positioning the first mold part proximate to a second mold part thereby forming a lens cavity with the media and conductive material and at least some of reactive monomer mix in the lens cavity; and
exposing the reactive monomer mix to actinic radiation.
2. The method of claim 1 wherein the conductive material capable of receiving energy via a radio wave is deposited on to the media via ink jetting.
3. The method of claim 2 wherein the media comprises a binder layer and the method additionally comprises the steps of:
depositing the binder layer onto one of the first mold part and the second mold part; and
ink jetting the conductive material onto the binder layer.
4. The method of claim 1 wherein the media is in contact with one or both of the first mold part and the second mold part.
5. The method of claim 2 wherein the conductive material is ink jetted in a pattern proximate to a circumference of the ophthalmic lens and outside of a field of vision when the ophthalmic lens is placed on an eye.
6. The method of claim 1 wherein an energy receptor comprising the conductive material capable of receiving energy via a radio wave comprises conductive fibers.
7. The method of claim 6 wherein the conductive fibers comprise carbon nanotubes.
8. The method of claim 7 wherein the conductive fibers comprise nanostructures.
9. The method of claim 7 wherein the binder layer comprises a pigment.
10. The method of claim 3 wherein the binder layer comprises a prepolymer.
11. The method of claim 3 wherein the binder layer comprises reactive monomer mix.
