As we all know, the main components of the old generation of HEMA hydrogel contact lenses are a few simple polymers such as HEMA and NVP. Even so, in the past 20 years, these simple optical grade contact lens materials used by domestic contact lens manufacturers still need to be imported from Germany and Japan, and the upstream raw materials are controlled by foreign manufacturers. Silicone hydrogel contact lenses require many complex raw materials, which are high molecular weight polymers formulated from nearly 20 monomer materials. Some of these materials are controlled or bought out by the four major contact lens manufacturers in the United States, and some are not sold to China or sold at more than twice the price.

Materials are the foundation of industrial upgrading. The pharnorcia industry spire team has overcome a large number of technical problems and successfully developed more than 20 monomer materials needed for silicone hydrogel contact lenses. The R & D, production, sales and commercial use of more than 20 monomer materials have solved the problem of supply chain sticking. It is the only enterprise in China that produces ophthalmic materials and exports them to developed countries in Europe and America. Most of the materials of domestic high-end medical equipment enterprises are imported. Our company not only develops and produces materials by itself to solve the supply chain bottleneck problem, but also sells these materials to large enterprises in developed countries to verify the quality reliability.


Silicone hydrogel contact lenses with pharnorcia's own materials, technology benefits the people, making the eyes of 700 million myopic people in China healthier, and achieving healthier, safer and more comfortable user needs. Self-sufficient contact lens suppliers of key core materials will replace imports in an all-round way, allowing domestic users to wear silicone hydrogel contact lenses with higher quality and cost performance, which will bring revolutionary contributions to 700 million myopic users in China.
