Abstract: A contact lens includes a lens body and an embedded module. The lens body has an optical portion and an annular wearing portion that surrounds the optical portion. The embedded module includes a pre-mold body being made of an eye-friendly material and a circuit structure that is embedded in the pre-mold body. The pre-mold body is entirely embedded in the annular wearing portion of the lens body, and the pre-mold body is ring-shaped and surrounds an outside of the optical portion. The pre-mold body and the lens body are gaplessly connected to each other so as to jointly form a connection interface therebetween that is spaced apart from a rear surface and a front surface of the lens body. Surfaces of the circuit structure are partially flush with an outer surface of the pre-mold body, and are connected to the annular wearing portion.

Abstract: The invention is generally related to a method for producing, in a relatively efficient and consistent manner, embedded or hybrid silicone hydrogel contact lenses, and also to unprocessed embedded or hybrid silicone hydrogel contact lenses, according to conventional cast-molding technologies. A method of the invention involve use of a polymeric non-reactive diluent in preparing a polymerizable composition for forming the silicone hydrogel material of the unprocessed embedded or hybrid silicone hydrogel contact lens, which is cast-molded with a lens mold. The unprocessed cast-molded embedded or hybrid silicone hydrogel contact lens has no or a minimal water-swelling degree, so that lens distortion or delamination during the hydration of the unprocessed embedded or hybrid silicone hydrogel contact lens.
