Essilor Definity Progressive Lenses Now Available In Trivex Material

By Essilor News


DALLAS — (October 5, 2007) —Essilor of America is now offering its DEFINITY™ lenses in PPG’s Trivex® material. The new DEFINITY lens with Trivex material combines the strengths of Essilor’s premium DEFINITY progressive lens design and DUAL ADD® Technology with Trivex material – and marks the first time Essilor is offering Trivex as a lens material option in one of its designs.

“At Essilor, we consistently provide our customers with the very best lens options to prescribe for their patients. By partnering with PPG to bring the Trivex material to DEFINITY progressive lenses, we are adding yet another product offering for ECPs, who are already dispensing Trivex, to our already exceptional line of lenses ,” said Carl Bracy, Essilor Vice President of Marketing.

DEFINITY uses the patented DUAL ADD Technology to provide the widest intermediate vision and the least amount of unwanted peripheral distortion and astigmatism in a progressive design. The DUAL ADD Technology also allows for a smoother transition between all distances, for more comfortable vision and easier adaptation into a progressive lens. Additionally, DEFINITY features GROUND VIEW ADVANTAGE, which helps to minimize distortion and flatten the field of vision – providing clearer vision when looking down. The more natural field of vision resulting from the GROUND VIEW ADVANTAGE combined with the impact resistance and UV blockage of Trivex material offers another safe lens option for presbyopes who lead busy, active lives.
