Trivex vs Polycarbonate lenses


We often get asked what the major differences are between polycarbonate and Trivex and why we choose to use Trivex lenses in our sunglasses. Here's why:

Visual Clarity

Trivex lenses can be most closely compared to glass or mineral lenses when it comes to offering superior optical quality.  Trivex has a significantly higher ABBE value than polycarbonate, which measures the chromatic aberration, aka clarity, of a specific lens material.


Trivex is stronger, lighter and more impact resistant than polycarbonate, making it the perfect lens for outdoor adventures. Not to mention, Trivex resistance to stress and cracking makes for a durable lens material when it comes to combatting the normal wear and tear sunglasses experience in everyday life.

How They Are Made

A big difference between poly lenses and Trivex is their manufacturing process. Polycarbonate lenses are injection molded. It is a quick process, resulting in a weaker material more likely to crack under stress. Trivex is made from a thermal casting process, where the material is filled into a cast and allowed to cure over time, several hours, before being removed.

Trivex was first developed by the military as an advanced material to be used as visual armor in helicopter and fighter jets.  The requirements for a new visual shield were to be extremely impact, temperature and chemical-resistant while providing superior optimal clarity.

After it's proven success in military aircraft, Trivex material  its way into the eyewear industry, first in safety glasses and eye protection because of its impact and chemical resistant properties and then into the sport and fashion sunglass world. 

What About Glass?

It goes without saying thatTrivex is more impact-resistant than glass, which is important especially when it comes to hard use sunglasses. But that's not the only benefit that Trivex has over glass lenses. There are a few reasons to skip glass lenses in favor of Trivex.
