Abstract: A color image patch for use with contact lens includes an attachment layer having one side for adsorbing to a surface of a contact lens, and an image layer connected to another side of the attachment layer and having an ornamental design provided thereon. Before wearing the contact lens, a wearer first selects a color image patch with favorite ornamental design and then attaches the attachment layer of the color image patch to the surface of the contact lens. The ornamental design on the image layer of the color image patch being adsorbed to the contact lens is located at a position corresponding to a wearer's iris and capable of changing the shape, size and color of the wearer's iris without influencing the vision correction function of the contact lens. Therefore, the color image patch gives the contact lens additional function and increased usefulness.

Abstract: A method of manufacturing color contact lens includes the steps of providing a rubber pad having a pressure bearing surface and filling C/M/Y/B coloring agents in a first inkjet printer; causing the first inkjet printer to jet the C/M/Y/B coloring agents on the pressure bearing surface of the rubber pad to form a color image layer; transferring the color image layer from the rubber pad onto an inner surface of a concave mold; injecting a lens material into the concave mold; pressing a convex mold against the concave mold to form a lens layer on the color image layer; and curing the color image layer and the lens layer to form a color contact lens. With the method, the color image layer can be formed using the inkjet printer without an increased thickness, enabling mass production of relatively thin color contact lenses at shortened time and lowered defect rate.
