ABSTRACT:
Disclosed are a colored contact lens and a method for manufacturing thereof, which forms a lens body by supplying a lens material onto a lower mold, molding a lens body with an upper mold and forms a cut portion and an optical portion by cutting off an upper surface of the lens body, and then forms a lens cover by forming an iris-colored part through printing on the cut portion and then supplying the lens material again onto the lens body, thus enabling mass production of the colored contact lens which does not cause any discomfort.
