Silicone hydrogel contact lenses are not a simple product upgrade, but a radical change.

The formulation material is the most critical technology for silicone hydrogel contact lenses, and its chemical structure is more than 10 times more complex than that of traditional HEMA contact lens materials.

Silicon material is a hydrophobic material with high oxygen permeability, while the silicon material required by contact lenses is not only high oxygen permeability, but also extremely hydrophilic, which is very difficult. Almost no one can solve the relationship between high oxygen permeability and surface lubrication. Therefore, the technology and science in this field have been limited by the control of international giants for a long time. The patent formulas of the four world giants are different from low to high, and the formula development cycle is long. Difficult, few practitioners, not easy to obtain, coupled with silicone hydrogel lenses with highly complex technology, high quality control requirements, long application cycle for certification, forming a high threshold barrier to entry, so the current domestic and even the entire Asian market silicone hydrogel contact lens manufacturers are almost blank.

Having mastered the core technology of silicone hydrogel contact lens materials, pharnorcia has made breakthroughs and innovations for more than ten years, and has successfully developed the latest third-generation silicone hydrogel formula with all independent intellectual property rights, and the key core raw materials are all self-sufficient. It has broken the monopoly of a few oligarchs in Europe and the United States, and has exported nearly 50 European and American customers continuously for 16 years, creating a well-known brand of silica hydrogel materials in pharnorcia.
