Top 3 Reasons NXT is the Best Lens Material for Polarized Sunglasses


First, let's start with the basics: What is NXT?

NXT is a Trivex material, developed in the 1990s for use in military helicopter and fighter jet canopies for its ultimate clarity, durability, ultra-lightweight properties, and chemical resistance. As a result of the success in military aircraft platforms, the material was brought to the eyewear industry in the early 2000s.

There are many materials on the market for sunglasses lenses, but we use NXT because we think it's the perfect combination of function and flexibility—it performs great on the water (or wherever your adventure takes you), but also fits well into lifestyle sunglasses. So, why did we choose NXT and what makes it better than the alternatives (glass and polycarbonate)? Three major reasons below:

NXT is thicker than polycarbonate but is about 10% lighter. You may not think much of your glasses needing to be light, but when you're out on the trails or casting to tarpon in the flats all day, your sunglasses are the last thing you want to be messing with. Lightweight sunglasses mean that you can wear them all day in comfort.

NXT is also more durable, passing Z87.1 impact resistant standard and high-impact testing. We test our gear in the mountains and streams of Montana, and we know that durability matters. We want our gear to be tough, and sunglasses are no exception.

Where NXT most notably stands out to the end user is in its clarity. Already inspiring confidence in weight and impact resistance, NXT provides, according to the ABBE number rating system, approximately 33% more clarity than polycarbonate. Only glass lenses have a higher clarity value but there are several reasons to skip glass lenses in favor of NXT.

Where other eyewear companies upcharge and mask this material with a proprietary name, we at Breakline use NXT as the standard material in all of our polarized sunglasses. All our lenses are polarized and block 100% of UV rays. Many of our frames feature an anti-fog treatment on the inside of the lens, assuring our customers have every advantage by providing the utmost clarity and lightweight performance because, at Breakline, Vision Is Everything.
