When manufacturing high-end silicone hydrogel contact lenses, intraocular lenses, or OK lenses, a critical step is selecting safe and compliant coloring materials. RB247 (Reactive Blue 247), a proven product validated by the world’s leading ophthalmic companies, was developed specifically to meet these stringent requirements.

Dual Certification for Professionalism and Compliance
Safety is the lifeline of medical device materials. The safety and efficacy of RB247, the ophthalmic material supplied by Pharnorcia®, have been recognized by the highest regulatory authorities in both the United States and China. Not only has it been permanently listed by the U.S. FDA, exempting it from batch certification and allowing direct use in contact lenses, but it has also completed Master File registration with China’s NMPA, providing compliance assurance for the product’s entry into global markets.
Stable Quality and Supply
For B2B procurement, supply stability is just as critical as product quality. Pharnorcia® upholds high standards for its ophthalmic materials, ensuring RB247 maintains high purity (≥97.0%) and batch-to-batch consistency. With a stable monthly production capacity of 50 kilograms, it fully supports downstream customers’ commercial-scale manufacturing.

Clear Application and Color Rendering
The RB247 (CAS 109561-07-1) supplied by Pharnorcia® bonds firmly with lens materials through chemical bonding, making it resistant to leaching. It imparts a uniform, clear “aqua-blue” appearance to the product, fulfilling functional coloring requirements while enhancing operational visibility. As awareness of blue light protection grows, the market for blue light-filtering intraocular lenses is expanding rapidly at a compound annual growth rate exceeding 10%. Against this backdrop, ensuring the stable supply and compliance of core materials will be a critical step for ophthalmic product manufacturers in building supply chain advantages.
