The contact lenses can be roughly divided into hard and soft lenses, which are more comfortable to wear with soft mirrors, and the traditional contact lens structure. And its wearing situation, 73⁄4% brother 1 shown, when wearing, the contact lens 10 is placed on the surface of the eyeball 3 200918983, so that the light entering the eye is pre-refractive, so as to achieve the effect of correcting vision However, since the contact lens 100 will make it close to the surface of the eyeball when worn, the eyeball time will not be fully exposed to the air, and if worn for a long time (more than eight hours), the eye will be deprived of oxygen. The wearer's eyes will be extremely uncomfortable with redness (microvascular expansion), so the high oxygen permeability of the material is very important to the eye cells, otherwise the eye cells will be deprived of oxygen due to the long time of wearing the contact lenses. It causes eye diseases. At present, the materials of soft contact lenses are generally more common in silicone and water gel, among which: 1. Water gel: Although it is hydrophilic, it has low oxygen permeability and is dry. The lens will become hard and make the wearer uncomfortable. 2. Tannin: Although the silicone polymer has high oxygen permeability, it is not hydrophilic, and it can not transport nutrient solution and remove the waste's water-insoluble contact lens. It will not be easy to remove the eyeball, which will not only be visually optically affected, but also cause eye discomfort and injury. Therefore, it is not suitable as a contact lens material for extended wear. 3. Mixed product of water gel and silicone rubber (Ref 1-Ref 26): Hydrogel gel materials have the above advantages, mainly using silicone rubber (or fluorine-containing sand rubber to form oxygen permeability; while hydrogel components provide transport liquid and contact lenses) The slidability requirements, but the design and preparation of this material is very difficult, because the two chemically opposite materials are mixed together, while still retaining the optical clarity, which is like water and The oil is mixed together, but still can be the same as the light-transparent thin film. The main reason is that the oil-soluble silicone component cannot be dissolved in the water-soluble water-gel component, so when the silicone monomer and When the water-based monomers are together, phase separation usually occurs, and the material becomes turbid and opaque. Because of this, the hydrogel material has the advantages of the above two conventional materials, but the synthesis of the materials is extremely difficult, and the production is extremely difficult. Difficulties cause high costs and are difficult to promote. In view of the above-mentioned shortcomings of the soft contact lens structure, the inventors have made improvements to these disadvantages, and finally the present invention has been produced. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for forming a silicone contact lens, which has a relatively simple processing difficulty, can effectively reduce the production cost, and enhance the competitiveness of the product in 200918983. Another object of the present invention is to provide a structure of a political contact lens which can effectively extend the wearing time and avoid discomfort caused by oxygen deficiency of the eyes. In order to achieve the above objectives and effects, the technical means adopted include: a "mixing" step of uniformly mixing the transparent silicone substrate and the filling material into a mixed material; a "forming" step of mixing the mixture The material is formed into a lens body; an "extraction" step, the filling material in the lens body is extracted from the silicone substrate. The lens body formed by the above method is provided with holes which are densely distributed and communicate with each other on the surface and inside of the lens body. In order to achieve a more specific understanding of the above objects, functions and features of the present invention, the following description will be made in the following drawings: [Embodiment] Referring to Figures 2 and 3, it is understood that the molding method of the present invention mainly includes: Mixing "1", "forming" 1 2 and "extracting" 13 and the like, wherein the "mixing" step 11 is a water-soluble cerium-containing surface dispersion which is not polymerized and has water solubility. The agent or the water-soluble tannin extract is mixed with the polymerizable tannin to form a uniform mixed material, and the "forming" step is a method of synthesizing the mixed material into a transparent soft and flexible lens body by a standard polymerization method. 1. The step of "extracting" 13 is to extract the water-soluble filling material in the lens body 1 from the silicone substrate, so that the lens body 1 of the silicone material originally accommodates the water-soluble filling material. The space will form a dense and interconnected hole 2; when in use, when the lens body 1SS is worn on the surface 3 of the eyeball, the lens body 1 is brought into contact with the air to make the surface of the tear fluid or physiological saline (human) The tears contain considerable oxygen, and the oxygen-rich tears or physiological saline (artificial tears) will penetrate into the surface of the lens body 1 through the infiltration or wearer's blinking (ie, the eyelids will compress the lens). In the inner hole 2, it penetrates into the surface 3 of the eyeball, so that the surface of the eyeball is constantly supplemented with oxygen. Therefore, there is no eye discomfort or redness and redness in the long-term wear; The high oxygen permeability of the silicone material has the function of transporting liquid, which not only can help the sliding of the lens body 1, but also can transport nutrients and waste, and since the lens body 1 has the hole 2, it is not like the traditional silicone rubber. The lens-like effect of adsorbing 200918983 on the surface 3 of the eyeball. According to the above-mentioned silicone contact lens structure of the present invention, since the water-soluble entrapping material can be mixed with 矽], and after being molded into the lens body 1, the water-soluble chelating material is easily removed by hydrolysis, possibly There is no need to go through the plasma treatment, so there is no difficult bottleneck in the overall production, which can effectively reduce the cost of production and thus enhance the competitiveness of the product. The lens polymerization method of the present invention can be carried out by any polymerization method such as thermal polymerization or ultraviolet photopolymerization to promote polymerization. The thermal polymerization starts such as Lauroyl peroxide 5 isopropyl percarbonate, azobisisobutyronitrile, etc., which can be used to generate a free radical at a suitable high temperature to initiate polymerization. The photopolymerization initiator can be, for example, aromatic alpha-hydroxyketone, or tertiary amine plus one diketone. Additional additives may also be added to the silicone contact lens material, such as UV absorbers, pigment dyes and the like. In addition, in order to improve the contact lens process, a mold release agent, a wetting agent or the like may be added if necessary.

The method of forming a silicone contact lens according to claim 1, wherein the "forming" step is performed by a standard polymerization method. 3. The method of forming a silicone contact lens according to claim 1 or 2, wherein the filling material is a water-soluble silicone. 4. The method of forming a silicone contact lens according to claim 1 or 2, wherein the supplementary material is a water-soluble cerium-containing surface dispersing agent having no polymerizable group. 5. The method of forming a contact lens according to claim 3, wherein the chelating material is a water-soluble cerium-containing surface dispersing agent having no polymerizable group. 6. The method of forming a silicone contact lens according to claim 1 or 2, wherein the chelating material is a non-polymerizable organic solvent-soluble silicone. 7. The method for forming a rubberized contact lens according to claim 3, wherein the supplementary material is a polymer-free organic solvent-soluble silicone. 8. The method for molding a contact lens according to claim 1 or 2, wherein the entangled material is a non-polymerizable organic solvent-soluble surface-dispersing agent containing cerium. 9. The method for forming a contact lens according to claim 3, wherein the chelating material is a non-polymerizable organic solvent-soluble surface-dispersing agent containing cerium. 10. An improved structure of a silicone contact lens formed from a transparent silicone substrate as a lens body having densely spaced and interconnected holes in the surface and interior of the lens body.
