Trivex lens material
PPG TRIVEX® lens material for impact-resistant eyeglass lenses
Endless options.
Ultimate performance.
Your patients ask a lot of their eyes – ask the same of their lens
material
Life is visually demanding. In a single day, your patients subject their eyes to thousands of different
situations. And whether it’s reading an email, driving on the highway or playing a round of golf,
they rely on their eyes to give them the clear picture. Having eyewear that delivers continuous
performance is essential to getting the most out of life—and it all begins with the lens material
recommendation you make.
Not all eyeglass lenses are equal
Your patients’ lenses—just like your own—need to perform in any
situation. Unfortunately, most lens materials require a trade-off. If your patient wants the advantages
of thinner, high index lenses, they’ll need to accept heavier and less durable lenses. To provide
the high optical quality of standard plastic lenses (PPG CR-39® monomer), the trade-off is less
strength and reduced durability. To benefit from the impact resistance of polycarbonate lenses, your
patient will have to sacrifice visual quality. And then there’s PPG TRIVEX® lens
material…
Trivex material provides the perfect combination of optical quality, lightweight comfort,
strength and protection—the critical performance characteristics called for in everyday living.
Endless options, ultimate performance
As the foundation of all eyewear, the lens material determines how well a lens
will perform in real life situations. That means the lenses you fit on your patients have to provide just
what their eyes need at any given moment. Trivex material is a unique, scientifically-advanced
category of lens material developed to provide the best balance of all performance properties –
clear, light, thin and strong.
Clear vision
For reading, computer work, driving, and any time vision acuity is important, Trivex
material provides the optical quality that optimizes corrective prescriptions and helps to reduce eye
strain.
Lightweight comfort
Trivex material is one of the lightest lens materials on the planet. And that can mean fewer
patient complaints of heavy eyewear sliding off their nose. Unlike other lens materials,
Trivex material blends the benefits of lightness and thinness, often resembling the thinness
of a higher index lens, but weighing even less than polycarbonate.
Thin
Trivex material enables eyeglasses that are the perfect balance of performance and comfort all within
a thin lens for most prescriptions.
Strength and durability
For the demands of everyday living, eyeglass lenses need to provide protection from unexpected
impact, breakage and from the sun’s harmful UV radiation. Unexpected physical contact can happen
at any moment. Trivex material provides high impact resistance when it is needed
most—like while playing sports or working in a hazardous environment.* The durability and
robustness of Trivex material—plus its stress-free characteristics—make it an
excellent choice for rimless (or drill-mount) frames and any lightweight fashion frames that rely on
lenses for structural rigidity. And to protect your patients’ eyes from the sun, Trivex
material blocks 100% of harmful UV rays.
100% UV protection
Lenses made from Trivex material, whether clear or tinted, protect patients’ eyes by
blocking 100% of harmful UV rays.
Who should wear lenses made with Trivex material?
Lenses made with Trivex material are a great choice for anyone who leads an active life and
expects clear, crisp vision, lightweight comfort and the ultimate in protection from their eyewear.
Consider the patient’s prescription…
Trivex material provides precise optical performance for every prescription. The majority of
your patients—approximately 85%—fall within the prescription range of +3.00 D to -3.00 D and
will gain the most from the benefits of Trivex material in an attractive and comfortably thin
lens. For patients with more severe prescriptions or sensitivity to chromatic aberration, smaller frame
styles minimize any appearance of lens thickness.
A perfect fit for children’s lenses…
With Trivex material, children gain the benefits of impact resistance PLUS great optical
performance. Lenses made with Trivex material pass some of the optical industry’s
highest standards for impact resistance.* Even better, you can provide that protection without
compromising visual performance for reading and schoolwork.
Compatible with all lifestyles and frame styles...
For the fashion-conscious, lenses that provide optical quality, lightweight comfort, strength and
protection are always in style! Trivex material is a perfect fit for all frame designs, and
it is especially well-suited for rimless (drill-mount) and semi-rimless (supra) styles. The
robustness of Trivex material is unmatched by any other lens material, delivering
durability, ultra-lightweight comfort, and precise optics in an attractively thin lens that can
satisfy your patients’ individual styles.
