Are Trivex lenses worth it?

Are Trivex lenses worth it?

Trivex lenses tend to cost more than polycarbonate or standard plastic lenses. But if you want what many eye care professionals consider to be the best combination of safety, comfort, appearance and optical performance for most eyeglass prescriptions, the Trivex price tag may be an investment worth making.

Is Trivex thicker than polycarbonate?

Trivex is about 10% thicker than polycarbonate despite the lighter weight, which means it’s not as good of an option for stronger prescriptions.

Is Trivex more impact resistant than polycarbonate?

Trivex is a lighter weight material, but due to its lower index of refraction more curvature and thickness is need to achieve a given power. Impact Resistance Trivex claims to be as strong, or stronger than polycarbonate in impact resistance.

Are Trivex lenses clearer?

Trivex is a new material that is a stronger, more resistant, clearer alternative to standard polycarbonate, which is one of the best materials for prescription glasses on the market Not only is Trivex strong and lightweight, it also offers 100 percent protection from UVA and UVB rays, sharper central vision, and …

Is Trivex the same as polycarbonate?

Summary. Trivex has the impact resistance and inherent UV protection of polycarbonate. With a lower index of refraction, Trivex may be slightly thicker than polycarbonate, but is lighter, and can be surfaced to the same 1mm center thickness.

Who created Trivex?

In 2001, PPG Industries created a new purpose for a breakthrough plastic technology called Trivex. The urethane-based pre-polymer substance would come to offer three primary benefits for eyeglass lenses, including: Exceptional optical clarity. High-performance strength.

What is difference between Trivex and polycarbonate?

For any given prescription, Trivex is a lighter lens than its polycarbonate counterpart. This is because of its lower density which keeps its relative weight lower. On the other hand, a Trivex lens is marginally thicker than a polycarbonate lens in any given prescription.

What material has the most favorable optical properties?

Glass
Glass is most stable, scratch-resistant, and provides the best optical quality of all lens materials. However, since glass is more brittle than most materials, lenses made of glass must be tempered or heat-treated to give them more strength and make them safer to wear.

Is Trivex ballistic?

This makes Trivex another good option for safety glasses. They are about 10% lighter than standard plastic lenses. Trivex prescription safety lenses meet ANSI Z87+ high ballistic rating. Only Polycarbonate and Trivex meet the Z87+ High Impact Ballistic Standards.

Does Trivex block blue light?

The lightweight lens provides optimal visual quality and durability for children in need of corrective eyewear. Blokz Trivex lenses are made with a blue-light blocking polymer that is directly incorporated into the lens material to absorb blue light and combat the effects of digital eye strain.

Is Trivex lighter than polycarbonate?

Weight: Despite having less material due to the thinner lens, polycarbonate sunglasses are heavier than their Trivex counterparts. Trivex lenses are composed of a urethane-based monomer that has lower specific gravity than polycarbonate and is 10% lighter as a result.

Who owns Trivex?

* Both CR-39 monomer and Trivex material are manufactured by PPG Industries.
