Contact lens

A contact lens, comprising:

• a lens body including an optical portion and an annular wearing portion that surrounds the optical portion, wherein the lens body has a front surface and a rear surface that is opposite to the front surface and that is configured for being worn on an eye;
• and
• an embedded module including:
• a pre-mold body being made of an eye-friendly material, wherein the pre-mold body is entirely embedded in the lens body, and the pre-mold body and the lens body are gaplessly connected to each other so as to jointly form a connection interface that is spaced apart from the front surface and the rear surface, and wherein the pre-mold body includes:
• an inner optical layer, wherein the inner optical layer is embedded in the optical portion so as to divide the optical portion into a front optical layer and a rear optical layer that is spaced apart from the front optical layer;
• and
• an enclosing ring extending from a peripheral edge of the inner optical layer and embedded in the annular wearing portion;
• and
• a circuit structure embedded in the enclosing ring, wherein a partial surface of the circuit structure is flush with an outer surface of the enclosing ring and is connected to the annular wearing portion.
