Contact lenses are contact lenses. Many myopic patients who love beauty have used them, but the experience of using them is very different. Many people have such questions, how to choose contact lens materials?

The new generation of young people are pursuing the latest technology and the best experience. The same is true in the selection of contact lens materials. It is the goal to experience the best wearing experience and experience the latest technology.

What kind of contact lens material is a better choice? The answer is: a contact lens material that can breathe.

Wearing hydrogel lenses for a long time may cause or be accompanied by significant corneal swelling, corneal dehydration (dry eye disease), upper corneal epithelial arcuate lesions (SEAL), corneal edema, decreased vision, and decreased nerve ending sensation depending on the corneal hypoxia. Corneal limbal vascular hyperplasia, corneal epithelial and endothelial function decline and other problems, the eyes are prone to redness, dryness and itching, and corneal hypoxia is very common.

The oxygen permeability of contact lenses of traditional materials (hydrogel, HEMA) is only about 10, while the Dk/t value of silicone hydrogel materials is 100-160, and the oxygen permeability can be improved by 6-10 compared with hydrogel materials. times more.

Therefore, for breathing contact lenses, silicone hydrogel materials are the best choice! ! !

Materials are the basis for industrial upgrading. The pharnorcia industry spire team overcame a large number of technical problems and successfully developed all the more than 20 kinds of monomer materials required for silicone hydrogel contact lenses. The research and development, production, sales and commercial use of more than 20 kinds of monomer materials have solved the problem of supply chain bottlenecks. It is the only enterprise in China that produces ophthalmic materials and exports them to developed countries in Europe and America.

pharnorcia's own material, silicone hydrogel contact lenses, to achieve healthier, safer and more comfortable user needs. The key core materials are self-sufficient contact lens suppliers, fully replacing imports, allowing domestic users to wear silicone hydrogel contact lenses with higher quality and price, and giving you the best choice of contact lens materials.
