Abstract:
One embodiment of a contact lens includes a lens body configured to fit directly on the surface of the eye and legible characters positioned on the lens body. Another embodiment of a contact lens comprises a lens body including polymeric material and a lens enhancing material (e.g., ink, silicone material, medicament material, and the like) encapsulated in the polymeric material. The lens enhancing material can be in the form of isolated sections distributed in the surrounding polymeric material. Methods of making contact lenses include forming a first lens layer including a first surface, forming a pattern on the first surface, and forming a second lens layer over the pattern.
