Since 2005, Pharnorcia has been committed to the research and development of the third generation of biocompatible optical high-purity hydrophilic silicone hydrogel polymer composite materials, developed high-purity VMA（CAS # : 3195-78-6）, and realized a formula which makes special long-chain silicon materials and hydrophilic materials pefect coupling , whose technology has achieved the revolutionary function of the third generation of silicone hydrogels.

Based on the company's accumulation of material technology, optical design technology and mold development technology, Pharnorcia has independently developed more than 20 new silicone hydrogel contact lens materials. Triss (CAS#: 17096-07-0) and Sigma (CAS#: 69861-02-5) are the most commonly used silicon-containing materials for silicone hydrogel contact lenses,and International big-name companies Johnson & Johnson and British manufacturer Saffron both use these two monomer materials.

Pharnorcia has 17 years of experience in research, development, production and export of silicone hydrogel materials.Since its establishment, the company has exported more than 600 batches of materials and more than 20 series of biological materials to developed countries. It has established an internationally leading and the only domestic research and development, production and sales platform for silicone hydrogel contact lens products and special materials. The series of products successfully developed have undergone nearly 20 on-site inspections by world-class giants such as Johnson & Johnson, Bausch & Lomb, Cooper, Alcon, and other global partners, and have passed their quality management system certification and become a global designated supplier of many Fortune 500 companies.

Pharnorcia was the first company in the world to supply materials to Cooper. After verification and strict evaluation by quality control system, on-site audit and other parties, Cooper has confirmed the qualification and applicability of Pharnorcia products. Pharnorcia has thus become the first manufacturer in the world to provide qualified VMA (CAS #: 3195-78-6). Cooper is famous for its stable product quality, which has led Cooper to develop Biofinity's third generation silicone hydrogel contact lenses that sell well all over the world.

With 11 years of experience in producing and exporting Triss (CAS #: 17096-07-0) and Sigma (CAS #: 69861-02-5) materials, Pharnorcia is the most popular supplier of silicon hydrogel contact lens materials with stable quality and reasonable price.
