Pharnorcia A621 (PDMS-diMA, CAS#:58130-03-3): The "Invisible Lens Experience" Engine Empowering 140 Million Users Globally

Featuring a dual-core molecular architecture, A621 breaks the traditional barrier where high oxygen permeability and optimal refractive index could not coexist:

10x Enhanced Oxygen Transmission:Enables corneas to 'breathe' freely day and night, effectively eliminating eye redness.

Precision-Engineered Refractive Index: Lenses are 40% thinner, delivering sharp, clear vision and precise correction for myopia and astigmatism.

Leveraging its ultra-high purity (99.9%) and 19 years of closed-loop technological refinement, pharnorcia's ophthalmic material PDMS-diMA (A621, CAS#:58130-03-3) has secured China NMPA certification and passed over 20 rigorous international audits by industry giants like Johnson & Johnson and Alcon. It stands as the gold standard for silicone hydrogel contact lenses.

Serving over 100 global ophthalmic companies, pharnorcia brings the liberating feeling of 'forgetting they exist' to every pair of eyes – enabling users to see the world in its purest form.
