In general ophthalmic lenses, to make the lens colored, it is usually coated with a colored film, or directly dyed on the lens. For example, Patent Publication No. CN104246580 B discloses a colored contact lens, which contains a central visual area in the contact lens. Unlike the surrounding display area, which is a colored area, the coloring method of the contact lens is to use dyes to uniformly color the surface of the lens or to partially print a pattern inside. For example, the iris-forming portion on the surface of the lens molding die is coated with a colored monomer component, and after the film is formed, the lens monomer component is filled and polymerized. Another method is a contact lens in which the colored part is embedded in the lens material. These methods mainly suppress the elution of the colorant and ensure the smoothness of the lens surface.
