Introducing Nylon Optics

The biggest innovation in lenses since polarization.

Beginning in 2020, all Rheos shades will be outfitted with the latest innovation in sunglass technology: Nylon Optics. These lenses are clearer than glass and light enough to be the most comfortable sunglasses you've ever worn. This technology allows us to develop optics of the highest quality and class at an accessible price point like no one else in the world.



The higher the value, the lower the chromatic aberration (blurriness and optical distortion).

The clarity is more brilliant than glass, without the excess weight of glass or danger of broken shards coming in contact with your eyes.



Our featherlight lenses provide long-lasting comfort while still maintaining a substantial hand feel for the lens and frame. Say goodbye to tension headaches.



Our nylon lenses hold up against the toughest adventures. And for even the most extreme circumstances you can rely on our Saltwater Promise!


No Better Lens. No Better Price.

Our Nylon Optics capture all the benefits of a glass and polycarbonate lens without the drawbacks. The only way to see and feel the difference is to try them.


How do they float?

The basic principles of buoyancy apply: when an object displaces water, the heavier of the two sink. Meaning, if 2 oz. of water is displaced and the water weighs just barely more than the object, then the water sinks and the object floats. With that in mind, our frames are made of the highly durable and ultra-lightweight specialty Nylon material. These frames weigh approximately 30% less than similar sunglasses moulded in polycarbonate, all while maintaining a hyper-durable structure to ensure comfort for long-term wear and floating capability. Because our shades weigh less and displace the same amount of water as standard frames, ours float while theirs sink.

How do polarized lenses work?

Light is made up of waves traveling in different directions. Vertical light is useful to the human eye; it helps us see. But when light strikes a flat surface, such as a lake, snow, or even your car or boat windshield, it changes to horizontal light and creates a glare. Polarized sunglasses block horizontal light, so you don’t see the glare. And nobody likes glare. It’s just about that simple.

Why is 100% UV-ray protection so important?

The most harmful sun rays are those above 400 nanometers. Our lenses are carefully designed to protect all UVA and UVB rays that are above 400. Over time these rays can cause long-term, irreperable damage to your eyes!

What is anti-fog for sunglasses?

Our premium lenses include a finish of dual-sided anti-fog coating. Lenses are susceptible to fogging in moments of highly-contrasted temperatures (such as walking from indoors to outside, or sweating while it is cold outside). With our anti-fog coating, the frames will detect the fogging of the lenses and quickly — and automatically — clear the lenses so you do not need to remove them and do it yourself.

What are anti-scratch lenses?

We built our lenses to withstand the wear and tear of everyday use. An anti-scratch coating helps to ensure they will be as good as new from adventure to adventure. With glass-like clarity, polycarbonate lenses give you the protection you need without the risk of shattering glass near your eyes. 

Our frames are comprised of a thermoplastic that starts as a solid material in the form of small pellets. In a lens manufacturing process called injection molding, the pellets are heated to 500 degrees until they melt. Compressed in extreme pressure scenarios the lens is complete in less than five minutes. Because of this unique process, polycarbonate lenses are much more impact-resistant than both regular glass and other plastic lenses. 

These materials are relatively "soft" — which means they can absorb energy without lens-fracturing. It is also the lightest lens material made and yet offers far greater impact resistance than glass or plastic.

What is hydrophobic coating for lenses?

We didn't hold anything back when it came to a feature-rich lens. Typically reserved for the highest-priced adventure shades on the market, the Rheos lens includes a speciality hydrophobic coating, which acts as a water-repellent, helping water bead off the lens without settling in and covering your view. 

What is oleophobic coating on sunglasses?

With so many premium features packed into one lens, we added a final oleophobic coating to help protect each side of the lens from wear and tear of salt water, and oils from fingers and usage.

What is monosaccharide coating on sunglasses?

That's not a thing. We just wanted to end on a sweet note. And monosaccharide is sugar.
