Summary:A contact lens includes a lens body and a color ink layer. The color ink layer is embedded in the lens body and includes a plurality of color ink membrane thicknesses. The color ink membrane thicknesses are different to each other. The color ink layer includes a plurality of color ink elements, and the color ink elements include M types of areas, in which M is a natural number greater than one. The color ink layer further includes color ink membrane thicknesses from a number one color ink membrane thickness to a number 1+n color ink membrane thickness, in which n is a natural number greater than zero. These color ink membrane thicknesses and the M types of areas form M*(1+n) units of color ink concentration, and the M*(1+n) units of color ink concentration forms a multicolor pattern in the lens body.
