ESSILOR DEFINITY™ PROGRESSIVE LENSES NOW AVAILABLE IN TRIVEX® MATERIAL
DEFINITY™ Lenses With Trivex® Technology Provide Ideal Package for Active Lifestyles
LAS VEGAS, Oct. 5, 2007 — PPG Industries, Inc. and Essilor of America have joined forces to offer Essilor’s DEFINITY™ line of lenses in PPG’s Trivex® material. The new DEFINITY lenses with Trivex material offer an ideal combination for patients – particularly those leading active lifestyles – by blending the optical, safety and comfort benefits of Trivex material with the strengths of Essilor’s premium DEFINITY progressive lens. This introduction also marks the first time Essilor is offering Trivex as a lens material option in one of its designs.

“DEFINITY lenses have been specifically designed for superior optical performance, so it makes sense for them to be offered in Trivex material, which complements this quality, while providing the added benefits of safety and comfort that are desired for today’s patients,” said Christine Camsuzou, general manager of optical materials, PPG Industries, Inc. “We share Essilor’s belief that all consumers – including presbyopes – should have the best when it comes to their vision, and are pleased to combine our expertise to make this exciting new lens option available.”

The high Abbe value and light transmittance level of Trivex material, paired with DEFINITY’s patented DUAL ADD® Technology – designed to enhance intermediate vision and reduce peripheral distortion and astigmatism – help to provide optimum optical clarity for the progressive lens wearer. The DUAL ADD Technology was also designed to promote a smoother transition between all distances, for more comfortable vision and easier adaptation into a progressive lens. This attribute, combined with Trivex material’s lightweight qualities, delivers a lens patients will hardly notice on their faces, for ease of use all day long. Trivex material also offers impact resistance and automatic UV protection. These features, paired with a more natural field of vision resulting from DEFINITY’s GROUND VIEW ADVANTAGE™, offer an ideal lens option for presbyopes with active lifestyles.

Trivex material is also ideal for rimless frames, because the material is less sensitive to heat during drilling than other lens materials so holes are drilled cleanly with no distortion, melting or fracturing. Due to the durability of Trivex material, the lens holes also retain their size and shape over time with normal wear. The expanded availability of DEFINITY in Trivex material means eyecare professionals can more confidently recommend the DEFINITY progressive design for patients desiring fashionable three-piece and semi-rimless frames.
