Unfortunately, most lens materials require a trade-off. If you want the advantages of thinner, high index lenses, you’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, you 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.
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 wear have to provide just what your 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.
Trivex material is one of the lightest lens materials on the planet. And that can mean fewer complaints of heavy eyewear sliding off your 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.
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 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 your 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 prescription…
Trivex material provides precise optical performance for every prescription. The majority of 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 those 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 individual style.
