Hey, it’s Eric from the Sunglass Underground!  Today, I’m going to explain the difference between the two lens materials we use to custom-make your prescription sunglass lenses in our advanced lab. Since you get to choose the lens material, understanding their features and benefits will help you make the perfect choice. And because it’s direct from our lab to you, you’ll save 50 to 70%!

There are two materials we use: Lumina Polycarbonate and Lumina Trivex.  Both are impact resistant, and both give you full protection from the sun’s harmful UV rays.

Let’s take a look at the differences between them.

Polycarbonate was originally developed for the aerospace industry and used to make the windshield of the first space shuttle. Later, optical engineers realized they could use it in sunglasses, and create a lightweight, impact-resistant lens.

Since then, Polycarbonate lenses have become the standard for active sports sunglasses.  They have superior impact resistance and they’re 20% thinner and 30% lighter than standard plastic lenses – they’re super tough, and very hard to break.

Trivex is the newest high-tech lens material. It was also developed for NASA and the military, and like Polycarbonate, it’s very tough. In fact, it’s even stronger than Polycarbonate, it’s 10% lighter, and it has an optical clarity rating about 40% higher than Polycarbonate. Polycarbonate is not as clear as the human eye, Trivex is.

So, to sum it up: Both Polycarbonate and Trivex have high-impact resistance. Trivex is stronger, but both are excellent for sunglasses and active sports.  Lumina Polycarbonate and Lumina Trivex both provide full protection from the sun’s harmful UVA, UVB and UVC rays. And both, have our proprietary scratch-resistant, zirconium hard-coat.

Trivex is a little lighter than Polycarbonate, but here’s the big difference between the two materials:  Trivex has a much higher optical clarity. It mimics the human eye with a clarity rating significantly higher than Polycarbonate.

And there you have it!  No matter which material you choose, you’re gonna love the sunglasses we make for you! This is Eric, from the Sunglass Underground, where the more you know about lenses, the better we look!
