Hydrogel lens including a removable media insert
An ophthalmic device includes a hydrogel lens and a media insert removably attached to the hydrogel lens. A method for removably attaching the media insert to the hydrogel lens includes receiving a first hydrogel lens including an annular opening, at least partially inserting a media insert into the annular opening of the first hydrogel lens, removing the media insert from the annular opening of the first hydrogel lens, receiving a second hydrogel lens including an annular opening, and at least partially inserting the removed media insert into the annular opening of the second hydrogel lens.
1. An ophthalmic device comprising:
a hydrogel lens comprising an optic zone and a peripheral zone that is outside of the optic zone;
two or more raised portions in the peripheral zone of the hydrogel lens; and
a media insert removably attached within the optic zone of the hydrogel lens.
2. The ophthalmic device of claim 1 , wherein gap portions are located in between the raised portions and allow for oxygen transmission and tear flow.
3. The ophthalmic device of claim 1 , wherein an upper surface of the media insert partially protrudes from an outer surface of the hydrogel lens.
4. The ophthalmic device of claim 1 , wherein the media insert comprises one or more semiconductor devices.
5. The ophthalmic device of claim 1 , wherein the media insert further comprises one or more energization elements.
6. An ophthalmic device comprising:
a hydrogel lens comprising a relatively flat portion overlapping a center axis of the hydrogel lens; and
a media insert removably attached to the hydrogel lens.
7. The ophthalmic device of claim 6 , wherein the media insert is removably attached to the hydrogel lens through an adhesive fit.
8. An ophthalmic device comprising:
a hydrogel lens comprising an annular opening configured to receive at least part of a media insert; and
a media insert removably attached within the annular opening of the hydrogel lens.
9. The ophthalmic device of claim 8 , wherein the media insert comprises ribs at least partially along its circumference.
10. The ophthalmic device of claim 8 , wherein the media insert comprises two or more tabs along its circumference.
11. The ophthalmic device of claim 10 , wherein the tabs are made of a resilient material.
12. The ophthalmic device of claim 8 , wherein the media insert comprises a top annular portion over a bottom annular portion and define an annular step, wherein the bottom annular portion has a diameter greater than a diameter of the top annular portion.
13. The ophthalmic device of claim 8 , wherein the media insert is removably attached to the hydrogel lens through an interference fit.
14. A method for removably attaching a media insert to a hydrogel lens, the method comprising:
receiving a first hydrogel lens including an annular opening;
at least partially inserting a media insert into the annular opening of the first hydrogel lens;
removing the media insert from the annular opening of the first hydrogel lens;
receiving a second hydrogel lens including an annular opening; and
at least partially inserting the removed media insert into the annular opening of the second hydrogel lens.
15. The method of claim 14 , wherein the media insert comprises an attachment mechanism.
16. The method of claim 15 , wherein the attachment mechanism comprises ribs at least partially along the circumference of the media insert.
17. The method of claim 15 , wherein the attachment mechanism comprises two or more tabs along the circumference of the media insert.
18. The method of claim 14 , wherein the media insert is formed of a material that is more rigid than a material used to form the first hydrogel lens and the second hydrogel lens.
