Measuring just 12.7 millimeters in diameter, an orthokeratology (OK) lens serves as a precision “shaper” overnight—a beacon of hope for countless children seeking to control myopia and embrace crystal-clear daylight. Behind this lies decades of proprietary OK lens material formulations, once guarded as technical barriers by a handful of international companies.
Historically, domestic manufacturers primarily processed imported pre-fabricated materials (“buttons”), remaining constrained by upstream suppliers. Change began at the source. Pharnorcia® chose a more fundamental—and challenging—path: becoming an independent innovator and specialized supplier of critical orthokeratology materials.

Mastering Key Materials, Building a Foundation of Safety.
As Class III medical devices in direct contact with the cornea, OK lenses demand exceptionally stringent requirements for material oxygen permeability, biocompatibility, and physical strength. We have long focused on the independent R&D of core OK lens materials like high-purity silicone (fluorine) monomers. The quality of these “molecular building blocks” fundamentally determines the safety, efficacy, and comfort of the lenses.
Adhering to rigorous standards, defining the pinnacle of quality.
We set our own bar above international standards to ensure materials deliver critical performance. For instance, high oxygen permeability (DK value ≥100) is a core indicator for maintaining corneal health during nighttime “breathing.” Pharnorcia®'s efforts in OK lens materials aim to empower domestic lenses with the material confidence to compete at the world's highest level.
Empowering Industry Partners, Driving Independent Advancement.
From proprietary innovative monomers to consistently supplied high-quality OK lens materials, our solutions empower downstream manufacturers to build their own “material DNA,” achieving a critical leap from deep processing to source innovation. We value collaboration with industry peers to advance this journey together.

Enduring trust stems from unwavering commitment to quality. Pharnorcia®'s vision is to become a steadfast partner in China's myopia control initiative through professional, reliable OK lens material solutions.
