Trivex® material helps to differentiate your business by offering your clients a premium advanced, new technology product category that sets it apart from any other lens material.

Why dispense Trivex® material?

Trivex® material was developed to produce a unique combination of patient benefits: lightweight, improved protection, thin, superior clarity of vision and full UVA/UVB protection compared with older lens technologies.

Trivex® material offers patients what they want from a lens material.

Visual clarity: Trivex® material delivers edge-to-edge visual clarity that the patient perceives as on-par with the clarity of glass lenses and virtually eliminates color aberrations, especially in high Rx powers. The Abbe vaTrivex-Benefits_Optical Quality_chartlue of Trivex® material is 43 to 45, depending on lens manufacturer. The higher the Abbe value of a lens material, the more accurately the lens will align the spectrum of light waves that pass through it.

Lightweight: Trivex® material is the lightest commercially available lens material with a specific gravity of 1.11 g/cm3. This means, depending on the selected frame and Rx considerations, that eyewear with Trivex® material will feature the lightest weight lenses in the lower prescription range which is approximately 85% of all patients.

Thinness: Trivex® material is manufactured differently from other polyurethane Trivex-Benefits_Light and Thin_chartlens materials. This means that center thickness on minus power lenses can be as thin as high index lenses and meet the minimum edge thickness of 1.8mm required for most rimless and grooved frames. Trivex® material has a refractive index of 1.53 and is comparably thin to most other lens materials in low prescriptions.



UV protection: Trivex® material delivers inherent 100 percent UV blockage, important for long-term eye health.


High impact resistance: Lenses made with Trivex® material pass the American National Standards Institute ANSI Z87.1.2003* high impact test, making them on-par with polycarbonate lenses for safe wear in circumstances where Trivex-Benefits_Strength and Durability_charteye protection is necessary, as in sports or industrial work situations.

*ANSI Z87.1 High-Velocity Impact Test:
The American National Standards Institute (ANSI) has established one of the most stringent impact and projectile penetration standards for optical lenses. The standard specifies that high-impact lenses must pass high-velocity testing where ¼-inch steel pellets are shot at the lens at a velocity of 150 feet-per-second. Lenses made with Trivex material pass the ANSI Z87.1 High-Velocity Impact Test and the FDA Drop Ball Test.*
