Abstract
An ophthalmic device includes an enclosure, two immiscible fluids, an electrode, a dielectric, and an anion getter material. The enclosure is configured to mount on or in an eye of a user. The two immiscible fluids, including a first fluid and a second fluid, are disposed within the enclosure. The electrode is separated from the two immiscible fluids by the dielectric. The electrode is capable of forming a barrier layer during an anodization process when a voltage is applied across the electrode and the first fluid. The anion getter material is disposed within the ophthalmic device and is capable of gettering anion contaminants that inhibit the anodization process from forming the barrier layer.
Claims23
An ophthalmic device, comprising:
- an enclosure configured to mount on or in an eye;
- two immiscible fluids disposed within the enclosure, wherein the two immiscible fluids include a first fluid and a second fluid;
- an electrode separated from the two immiscible fluids by a dielectric, wherein the electrode is capable of forming a barrier layer during an anodization process when a voltage is applied across the electrode and the first fluid;
- and
- an anion getter material disposed within the ophthalmic device, wherein the anion getter material is capable of gettering anion contaminants that inhibit the anodization process from forming the barrier layer.
An ophthalmic system, comprising:
- an enclosure configured to mount on or in an eye;
- an insulating material disposed within the enclosure, wherein the insulating material includes an anion getter material disposed within the insulating material;
- and
- a conductive trace embedded within the insulating material, wherein the conductive trace includes a valve metal, and wherein the anion getter material is capable of gettering anion contaminants to inhibit the anion contaminants from diffusing through the insulating material.
