Since 2005, Pharnorcia has been committed to the development, production and global supply of the third generation of biocompatible optical high-purity hydrophilic silicone hydrogel polymer composites and intraocular lens monomer materials.


Among them, high-purity 2VN (CAS#:827-54-3) and 4VA (CAS#:637-69-4) are monomer materials for intraocular lenses. 2VN (CAS # 827-54-3) and 4VA (CAS # 637-69-4) are used in IOLs because of their high refractive indices. Therefore, 2VN (CAS # 827-54-3) and 4VA (CAS # 637-69-4) can make the intraocular lens thinner and achieve the same corrective effect.


2VN (CAS # 827-54-3) is a widely used intraocular lens monomer material because of the above characteristics. 4VA (CAS # 637-69-4) also has a high refractive index and is also used in the synthesis of intraocular lenses, depending on the choice of formula by the intraocular lens manufacturer.


Based on the accumulation of Pharnorcia’s material technology, optical design technology, and mold development technology, Pharnorcia has independently developed more than 20 new silicone hydrogel contact lens materials. International big-name companies: Johnson & Johnson, Bausch & Lomb, Alcon, Coopervision, UK Manufacturers Sauflon all use Pharnorcia monomer materials. .


Pharnorcia has 15 years of experience in the research, development, production and export of silicone hydrogel materials. The company has developed more than 20 kinds of biological materials, and has exported more than 600 batches of products to developed countries.


Pharnorcia has set up the international leading and the only domestic research and development, production and sales platform for silicone hydrogel contact lens products and their special materials.


Pharnorcia has successfully developed a series of products, which have undergone nearly 20 on-site reviews by world-class giants such as Johnson & Johnson, Bausch & Lomb, Coopervision, Alcon and other global partners. Through its quality management system certification, Pharnorcia has become the global fixed-point supplier of many Fortune 500 enterprises.


Pharnorcia was the first company in the world to supply scarce materials to Coopervision. After many verifications and strict evaluations such as quality control system and on-site audit, Coopervision Company confirmed the qualification and applicability of Pharnorcia products. Pharnorcia is known for its consistent product quality, which led Coopervision to develop Biofinity's third generation silicone hydrogel contact lens, which is selling well all over the world.


Pharnorcia has 15 years of experience producing and exporting 2VN (CAS # 827-54-3) and 4VA (CAS # 637-69-4) These materials are stable in quality and reasonable in price. Pharnorcia is the most popular supplier of materials for silicone hydrogel contact lenses. We will provide you with special customized services, welcome to contact us and get the best quotation.
