Pittsburgh-PPG Industries Inc. has initiated the CR-39 Licensed Lens Caster Program. The program recognizes lens casters who are dedicated to preserving the reputation of CR-39 monomer.

Sixty years ago, PPG Industries was awarded the patent for CR-39 monomer, which became the first resin widely used for manufacturing plastic ophthalmic lenses. Today, CR-39 represents the largest category of lenses sold worldwide.

"We feel we should defend the value behind the CR-39 trademark to ensure that the industry is receiving the authentic CR-39 monomer they have depended on for so many years," said Christine Camsuzou, PPG general manager of optical materials.

The CR-39 Licensed Lens Caster Program and its members will be highlighted in advertising and at industry trade shows throughout the year.
