PPG CR-39 Monomer

Because of our long history, we are a leader in the development and production of optical monomers and coatings. It all starts with our proprietary PPG CR-39® lens monomer. There is only one CR-39 monomer, and it only comes from PPG.
For more than seven decades, lens wearers have relied on our 1.5 index lens material, PPG CR-39 monomer, for outstanding optical quality and durability.
