In the evolution of materials for silicone hydrogel contact lenses, Pharnorcia® IEM-PDMS A702 (CAS: 878288-97-2) represents a pivotal breakthrough in oxygen permeability and comfort.As a polymer material specifically designed for ophthalmic applications, it serves as the "core foundation" for manufacturing next-generation high-end lenses.

As a polymer material, A702 (CAS: 878288-97-2) possesses a unique long-chain molecular structure that enables the formation of highly efficient oxygen transport channels.This ensures that even with prolonged wear, the cornea maintains oxygenation levels close to physiological standards.Unlike conventional silicon materials, A702 (CAS: 878288-97-2) undergoes specialized terminal functionalization, significantly enhancing its hydrophilic stability and effectively inhibiting the precipitation and accumulation of proteins and lipids.

These exceptional chemical properties not only endow the lenses with dual characteristics of "high oxygen permeability" and "high water content," but also provide wearers with a long-lasting, healthy, and air-like lightweight wearing solution at the fundamental level of material science.It delivers a seamless, innovative eye-care experience for wearers.
