依著色劑中所含溶劑之不同，用來製造著色鏡片之著色 劑可分為水性和油性兩類。其中，前者例如美商諾華公司 之美國專利公告第7, 255, 438號揭示-種製造著色隱形 眼鏡之移印方法，該移印方法包含以下步驟：“）提供一 以水性墨水於其上紋刻有圖樣之印台上；⑴藉由一移印 〇塾自印台移印具有水性墨水之該圖樣至隱形眼鏡形成模 的表面；（c)固化該具有水性墨水之圖樣，以形成一 膜；（d)充填鏡片材料至隱形眼鏡形成模之凹穴中；及 固化凹模中之鏡片材料以形成著色隱形眼鏡。由上述㈣ 〇,可看出此移印方法為了保持圓樣的完整性，須 該具有水性墨水之圖樣固化，然而此步驟卻會增長製 =隱形眼鏡的時間，使得生產效率降 壯生和肚生視覺關懷公司（〜…。hns。乂上商 ，之中華民國專利公告第588168號揭示一種 5 326傳利說明書(補件)\97-〇 1 \TF974503

Field of the Invention The present invention relates to a method of manufacturing a contact lens and a manufacturing apparatus thereof, and more particularly to a method of manufacturing a colored lens for a contact lens and a manufacturing apparatus therefor. [Prior Art] Coloring concealed glasses are often used for decorative purposes to change the appearance color of the wearer's red film. For example, a person with a brown or blue eye who wants to change to a green eye can wear a colored contact lens with a green pattern to cover the wearer's iris. The colorant used to produce the colored lens can be classified into two types, water-based and oil-based, depending on the solvent contained in the colorant. Among them, the former, for example, U.S. Patent No. 7,255,438, the entire disclosure of which is incorporated herein by reference to the entire disclosure of the disclosure of the disclosure of the entire disclosure of (1) printing the pattern having the aqueous ink onto the surface of the contact lens forming mold by a pad printing from the printing station; (c) curing the pattern having the aqueous ink to form a film; d) filling the lens material into the cavity of the contact lens forming mold; and curing the lens material in the concave mold to form a colored contact lens. From (4) above, it can be seen that the printing method is required to maintain the integrity of the round sample. The pattern with water-based ink is cured, but this step will increase the time of the system = contact lens, making the production efficiency lower and the health care company (~....hns. 乂上商, Republic of China Patent Notice No. 588168 No. 5 326 patent specification (supplement)\97-〇1 \TF974503 200934645 Coloring agent for coloring contact lenses' The binding polymer in the colorant can be shaped with the lens material An interpenetrating polymer network such that a colorant is embedded in the lens material to form a stable colored lens, thereby forming a finished lens having a high resolution pattern printed with a colorant, wherein the colorant is used The solvent is 1-ethoxy-2-propanol and isopropyl lactate, and in its examples it is disclosed that the colorant is imprinted into the front curve of the contact lens 'and the sample is degassed and dried in a vacuum of about 8 In addition, the related art includes, for example, the Republic of China Patent Publication No. 154651, which discloses a color liquid for forming a color pattern on a surface of a mold, which typically includes a solvent and a colorant, the solvent comprising a thermoplastic polymer. a coating material or a curable (thermosetting) coating material in liquid form; Republic of China Patent Publication No. 479149 discloses a method for coloring a contact lens and a lens thereof, which are used in processing The pigment and the mold produce a considerable vanaural force under the irradiation of ultraviolet (UV) lamp, so that the pigment adheres to the surface of the pvc mold during processing, so as not to fall off Dissolved by a lens; U.S. Patent No. 5,116,112 discloses a colored lens and a method of manufacturing the same, and it is mentioned in the scope of the patent application that the colored liquid coated in the mold for producing a colored lens is thermosetting. Or a thermoplastic, and U.S. Patent No. 5,12,121 discloses a colored lens in which the decorative pattern on the rainbow portion of the lens is made of a thermoplastic polymer. From the above, the color used in the previous case is known. The agent needs to be subjected to a dry curing step by hot air baking or UV lamp irradiation to maintain the integrity of the pattern after the colored lens is formed. In addition, even if the coloring agent is directly applied to the dry contact lens, it is necessary to 326. \#利手册(补件)\97-01\TF974503 c 200934645 The lens can be rehydrated by other drying methods to become a wet contact lens. For example, US Patent Publication No. 4,668,240 discloses the use of its color. The lens of the coloring agent's formulation must be at 50 before hydration. The vacuum is dried to remove the solvent and then cured at 90 ° C to form a complete colored contact lens.
