Abstract
Contact lenses having embedded polymer layers, and methods for forming the same are provided. In some aspects, the contact lens can include: a substrate; a metal portion coupled to the substrate; and a polymer layer attached to the substrate and the metal portion, wherein the polymer layer has one or more indentations. The metal portion can be associated with or a part of a power supply, antenna and/or circuit in various aspects. In some aspects, the substrate can encapsulate the metal portion and the polymer layer. In some aspects, a method can include: forming a metal ring; fabricating one or more components on the metal ring; forming a polymer layer ring having indentations; providing the metal ring and the polymer layer ring in a contact lens mold; and encapsulating the contact lens mold with conventional hydrogel, silicone hydrogel, silicone elastomer, polyacrylamide, siloxane-based hydrogel or fluorosiloxane-based hydrogel.
