Every day, as you scroll through your phone and stare at your computer screen, harmful blue light is quietly damaging your eyes. OMTP (CAS: 98809-58-6) is the “guardian” hidden within your lenses, filtering high-energy blue light at the source so you can enjoy a clear and comfortable visual experience.

What is OMTP?

It is a highly efficient benzotriazole UV/blue light-absorbing monomer. When copolymerized into lens materials, it precisely absorbs harmful blue light in the 350–450 nm wavelength range while maintaining high clarity and transparency—without a yellow tint or a thick, heavy feel. Unlike traditional coatings, OMTP is permanently bonded to the material matrix via chemical bonds, ensuring it never leaches out or migrates, and providing long-lasting, stable protection.
