Kaenon Sunglasses: Wear the Very Best

Buy Kaenon sunglasses at Stillwater Fly Shop

Kaenon® has been at the forefront of polarized lens construction since its inception in 2001. Stillwater Fly Shop is a big believer in Kaenon® sunglasses, and we’ve been selling them for quite a few years without a lot of fanfare. When our new website launched last fall, our focus was taken off some of the smaller products as we focused our energy on the bread and butter of our store: rods, reels, waders and other great fly fishing gear from top brands in the industry. Now that we’ve had a chance to catch our breath and catch up with our thoughts, I’d like to take a moment to properly introduce you to Kaenon® Polarized sunglasses. Seriously, what good is your new Sage ONE rod or your Abel reel if you are experiencing eye fatigue or blinding glare coming off the water? We’ve all been there, hopefully only once. Today I would like to introduce you to a handful of reasons why Kaenon® is at the top of the line in the polarized eyewear industry.

Information presented below is excerpted from Kaenon to preserve the integrity of the information.

About Kaenon

Kaenon (pronounced: KAY-nun) emerged in 2001 from an intense passion and a clear desire to never compromise. Kaenon was founded by two brothers who were unsatisfied with the sunglasses available on the market. Determined to create something better, they developed the proprietary polarized SR-91® lens — the world’s first non-compromising polarized lens. Wrapped in unique, California-designed frame styles built for comfort and performance, along with distinct colorways and hand-painted treatments unique to Italian craftsmen, Kaenon sunglasses became more than a reality, they raised the standard in performance eyewear.

Starting with the very first innovation, SR-91, Kaenon has continued to raise the bar within the optical industry, pioneering a variety of new eyewear options like Freestyle Progressive SR-91 polarized prescription lenses, non-polarized SR-91 and Kaenon Optical frames, so that everyone, regardless of their eyewear needs, can enjoy the Kaenon experience.

“Our conviction to never compromise isn’t just a way of thinking; it defines our way of living. We live our lives in pursuit of how we believe things should be. We question everything. We stay true to our own set of values. As a result, it is easy for us to filter the noise and make our decisions for ourselves. We’ve resolved to never compromise clarity for style, or comfort for performance.” – Darren Rosenberg, Co-Founder.


Never Compromise®
Since the beginning, Kaenon has set a course based on deep-rooted values that are inspired by our lives and embody our commitment to premium craftsmanship and a forward approach to style. From the creation of our proprietary lens technology to the comfort and performance of our frames, we strive to never compromise quality, authenticity, originality or family. Such is the ethos of Kaenon.

Quality: Every detail, from our advanced lens material to our frame hinges is engineered specifically for Kaenon. We choose the highest standards of quality and design a diverse selection of frame styles to ensure we are providing the finest product for all eyewear needs.

Authenticity: We create products that we want to wear. We surround ourselves with like minded athletes and individuals who share our core values. We stand behind our product and values; what we say, and who we are, is what you get.

Performance: We play hard and need eyewear that is up to the task, but we believe that style and performance are not mutually exclusive. From the first design sketches of our frames to our proprietary SR-91 lens material, everything we design is ready to perform with the highest expectations both on and off the field of play.

Originality: We recognize the ever growing sea of peers in the eyewear marketplace and the challenge to remain original in this widely monopolized industry. Rather than look to those around us for inspiration, we turn to our own lives and ask a few simple questions: What inspires us, personally? What eyewear do we want? How can we make peoples’ experiences better? We listen to the feedback of our customers and ambassadors and we strive to continually improve upon each new design. We strive to evolve ahead of the need all the while remembering our core values.

Family: It all started with two Southern California brothers in search of something superior. Their vision for what could be has reached around the globe. Family is in our DNA and, though we work hard, we make sure to enjoy life with those closest to us. To our employees, athletes and those loyal to the Kaenon brand: we welcome you to our Kaenon family.

Kaenon Innovation

Kaenon was born from the need for a better sunglass, when others fell short. Sure, everyone has a frame and a lens, but here’s what makes Kaenon distinctly different:

Glass wasn’t strong enough. Polycarbonate wasn’t clear enough. Neither material allowed for adequate customization of tints and Light Transmission Levels (LTL®). So we set out to develop our own, completely new lens material.

Kaenon’s proprietary SR-91® lens is the only lens material that offers 100% broad spectrum UV protection and combines the superior optical quality of the finest glass and the lightweight, strength and impact resistance of polycarbonate. All of the best properties. No compromises. No short-cuts.

Composition of an SR-91 Lens
Every Kaenon lens is created with our exclusive multi-layered treatment system to further enhance your unparalleled visual experience. While others might up-charge for these benefits, with every Kaenon lens option, the very best is our standard:

Hydrophobic Coating: Designed to shed water and snow from the surface of the lens. This prevents water spots from distorting your vision, and allows for easier lens cleaning
Anti-Scratch Hard Coating: This hard-coat layer is designed to further protect the lens from abuse and scratching
Glare 86® Polarizing Element: Our polarized SR-91 lens contains a proprietary film called Glare 86 designed to interact flawlessly with SR-91 for razor-sharp clarity and distortion free polarized optics
Anti-Reflective Coating: Absorbs light and prevents it from bouncing off the back of the lens into your eye, eliminating distracting bounce-back reflections
Flash Mirror Coating:* Designed and applied to provide cosmetic enhancement.

*Not every Kaenon lens is made with a mirror coating.

From day one, polarization has been a priority. Everything we make comes standard with our advanced polarized SR-91 lens. While we do offer non-polarized lens options in a variety of Kaenon frames, we remain committed to our Kaenon Polarized history and quality. The very best is our standard.

The foundation of our unique polarized lens technology is the combination of our SR-91 lens material and our proprietary Glare 86 polarized film.

SR-91 provides the ultimate in clarity, and Glare 86 – specifically engineered for SR-91 – offers exceptional polarizing capability and tunes the essential light in any environment to your specific needs with unparalleled Light Transmission Control (LTC) technology. A complex lens manufacturing process encapsulates the Glare 86 film into the SR-91 lens material, forming a bond so strong that the lens is guaranteed for life against cracking or splitting of the lens at drill-mounts, or delamination of the inner polarizing film and the lens material.*

*Please refer to our warranty policy for complete terms and conditions.

The high-performance, patented Kaenon Polarized SR-91 lens comes standard in everything we make – including prescription. SR-91 Rx is available in Single-Vision and our Freestyle™ Progressive. And every frame is Rx-adaptable.



Not content with creating an entirely new lens material, Kaenon continues to advance polarized eyewear with groundbreaking LTC technology. LTC technology is a combination of Kaenon’s proprietary Light Transmission Levels (LTL®) and the science behind the exclusive design of our lens tints.

Kaenon’s own select lens tints – Grey, Copper, Brown or Yellow – combine with each LTL to optically enhance, tune and improve visibility in any weather condition, activity or time of day.

GREY – A neutral tint that doesn’t alter color perception.

COPPER – Enhances color contrast, depth perception and detail recognition.

BROWN – A neutral tint that slightly enhances color contrast, depth perception and definition in low light conditions.

YELLOW – Superior color contrast enhancement and detail definition.



Regardless of lens tint or light transmission level, every Kaenon sunglass offers 100% broad spectrum UV protection, filtering out all the harmful effects of the suns damaging rays.

LTL 12: Our darkest lens (blocks 88% of visible light), performs best in bright, full sun conditions. Available in Copper, Grey and Brown lenses.

LTL 28: Half as dark as LTL 12 (blocks 72% of visible light), great multi-purpose lens performs well in all light conditions. Available in Copper and Grey lenses.

LTL 35: Great all-around lens (blocks 65% of visible light), significantly enhances contrast, optimum in hazy, changing and low light conditions. Available in Yellow lenses.

LTL 50: Our lightest lens (blocks 50% of visible light). Allows maximum light transmission for greatest detail recognition. Performs best in low light and hazy conditions.


Low quality frame materials just won’t work for us. They warp and bend, are too heavy and lack the performance capabilities we require. So, just like with our SR-91 lens material, we set out to provide a better frame design.

Each of our Italian-made frames is crafted from the finest materials to ensure the most premium comfort, durability and aesthetic achievable. From our memory retentive TR-90 frames, to our lightweight metals, every component, is chosen with a superior experience in mind.

Every Kaenon frame is inspired by our active California lifestyle. Incorporating specific geometry to maximize comfort and function, paying attention to flex-zones and measuring the load on pressure points so that each frame feels as good as it looks.

Our renowned product designer, Harald Belker, works meticulously to incorporate function into the design of every frame shape and style in a way that flows harmoniously, giving our frames a distinct look that evokes the spirit of Kaenon.

For maximum function and sport performance we use the highest quality TR-90 to construct all of our non-metal frames. TR-90 was selected because of its durability, flexibility, light weight and comfort. And because TR-90 retains memory and is temperature resistant, frames never lose their shape or need adjustment. Our metal alloy frames are manufactured to maintain a superior strength to weight ratio and are hypo-allergenic by design.

We manufacture all of frames in Italy because of its reputation for quality eyewear production and craftsmanship.

Our attention to detail extends right down to the screw used in every frame hinge. If a component doesn’t exist that’s just right for our glasses, we design one that compliments the style and performance intended of that frame. We specify only the best materials for our glasses, like stainless steel to prevent hinges from corroding, and hydrophilic Variflex rubber embedded into temple tips and nose bridges for slip-free security during activity. When designing a frame from the ground up, we take every opportunity to make it just as it should be.
