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 from 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 first color ink membrane thickness to a (1+n)-th 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.

A polarizing film includes: a polarizing layer; a coating layer at one side of the polarizing layer and to absorb wavelengths in an ultraviolet ray region; and a phase retardation layer at another side of the polarizing layer, wherein the coating layer has a thickness of about 15 nm to about 5 m.

The present disclosure provides a method of manufacturing a contact lens. The method includes: forming a color ink layer in a lower mold, wherein the color ink layer has a plurality of color ink membrane thicknesses, and the color ink membrane thicknesses are different from each other; assembling an upper mold with the lower mold; filling a transparent plastic material between the upper mold and the lower mold to cover the color ink layer; and solidifying the transparent plastic material into a lens body, so that the color ink layer is embedded in the lens body.
