Jilin Realcon Contact Lens Co.,Ltd. is the one and only production base of colored contact lens in northeastern three provinces, located in national pioneer park of Jilin hi-tech zone. Our company belongs to sterile third-type medical device manufacturing enterprise with the possession of autonomous center of research and development. We are possessed with a full set of top-ranking Korean automatic research and development team of producing contact lens equipment as well as complete production technology. Our company is established in 2010, with 6,600,000 RMB registered fund and 5000 square meter of floor space, with the total staffs of approximately 140, among which 60 staffs with the college degree or above. In 2010, we are certified the production enterprise license of third-type medical device. In 2011 and 2012, we are certified two times the medical device GMP certificate, while in the end of 2013, our company gains the invention patent of internal coating printing and dyeing technique. Our production technique introduces Korean advanced mixed process of half-molding and half-turning. The main advantages are the features such as flexible operation, low cost, long life length of lens, etc., which is extremely fit to the production of colored contact lens. The now available main equipments of our company are 60 production devices, 28 inspection devices and the majority is imported device. |
1. Our technique resolves the problem that the lens are directly printed and dyed as well as the problem of color fading problem. Internal and external surface is smooth, not easily precipitated protein, with good oxygen permeability, comfortable wear effect as well as healthy and safe. 2. Under the premise of cast molding and turning mixed technique, in combination with the previous mature printing and dyeing internal coating to produce colored contact lens, which resolves the shortcomings of traditional “sandwich” coloring process, which are high-cost, low- production efficiency as well as unsteady quality. For the moment, our company has already improved the production rate of internal coating coloring technique up to 60-75%. |  |
To perform the coating on the terrace die of contact lens, then print and dye the pigment with the printing machine, form a layer of organic thin film as well as pigmentary layer after the stage of intensifying temperature and fixing color. The organic thin film blocks very well the contacts between pigmentary layer and the eyes as well as resolves the problem such as colour fading problem of pigmentary layer and weakness of comfort degree of wearing contact lens, etc.
This layer of “film” prepared with the printing and dyeing technique of internal coating needs to be possessed with the following several features:
1. With favorable hydrophily, expansivity is similar to the lens material
2. With favorable biocompatibility, cause no stimulant and allergic reaction to the eyes
3. With steady and solid physical property, cause no easy fall off
4. With nonpolar material, it doesn’t easily absorb protein
5. With favorable optical effect as well as oxygen permeability property
The production scene performs GMP standard and 6s management as well as conducts a sectional-type cyclic inspection to the production process, guarantee the inspection to each lens of every process from the preparation of raw material to the final output, every process has been inspected and traceable. The packaging of contact eye lenses color lenses is operated inside the ten thousand grade clean area. Complete quality system is the strong guarantee to the health of consumer.
1. Our colored contact lens are the most strong one among the domestic production and technology capability.
2. We are the sole domestic company with a large-scale capability of producing internal-coating technique of colored contact lens.
3. We are the first company that has passed the assessment of sterile medical device quality system in Jilin province.
4. We are the single third-type production enterprise of sterile medical device in Jilin city.
5. We are the company that introduces the most diversified and latest models of contact lens among the domestic fields.
