About PPG Optical

Our overriding philosophy is a worldwide focus on total quality combined with technological leadership.

PPG is a leading producer of optical grade monomers used in the manufacture of ophthalmic lenses.  With more than 70 years of experience engineering and producing optical monomers and coatings, we are uniquely positioned to be a leader in the ophthalmic lens industry.

Our extensive line of optical monomers and coatings products includes PPG CR-39® monomer and PPG TRIVEX® lens material.  Developed by PPG in 1945, CR-39 monomer was the first plastic resin to be used in the manufacture of ophthalmic lenses and continues to be the leading lens substrate in the world.  Trivex lens material provides the unique combination of optical quality, lightweight comfort, strength and protection.

Our PPG HI-GARD® lens coating solution provides a durable, scratch-resistant coating on ophthalmic lenses made from plastic materials. The optical quality of plastic lenses is maintained, and lenses coated with Hi-Gard lens coating are four to six times more abrasion-resistant than uncoated lenses made from CR-39 monomer.
