Fin-Nor Technology

Lateral Line Performance Lens Technology

Enhance Your Vision. Heighten Your Senses.

Every fish has a lateral line—a system of sensory organs used to detect movement, vibration, and pressure gradients, giving them the ability to find their prey. The all-new Fin-Nor sunglasses were inspired by this technology and designed to give anglers heightened senses on the water.

Any good angler knows that fishing involves all five senses. Our new Lateral Line Performance Lens Technology will enhance your vision so you can better see what's happening beneath the surface, but it doesn't stop there. The clearer your eyesight, the more you can focus on your other senses, such as feeling the slight tug of a first bite or hearing the splash of a nearby fish.

Engineered for the Elements

Let's be honest—the ocean can be rough on gear. Keeping your lenses smudge and scratch free when battling against salt spray and sand is no easy feat. Which is why we've designed Fin-Nor sunglasses with enhanced abrasion resistance and hydrophobic coatings. With technology designed to withstand the elements anglers face every day, Fin-Nor sunglasses are the durable, scratch-free solution you need for all day fishing.

Precision Optics

Fin-Nor sunglasses don't just feel great; they work great too. When searching for signs of underwater monsters, you need clear vision to give you a realistic view of what's happening beneath the surface. Our distortion-free lenses enhance sight without distorting vision, making it easier for your brain to quickly identify and process what is happening on and beneath the water. In addition, our lenses decrease blue light transmission, keeping your sight clear even when facing fog, haze, or the glaring sun.

Tools for Anglers,
Frames Designed to Work for You

Fin-Nor lenses are designed to be the best in the world so our frames need to follow suit. Every frame has been custom-designed and built for all day comfort and long-term durability. Many frames also boast industry-leading features including low-profile, integrated spring hinges, integrated side shields and adjustable nose pads. But every frame was built to keep you fishing comfortably all day long.

  • High-performance, bio-based grilamid (plastic frames)
  • EN 1811 conforming, corrosion-resistant alloy (metal frames)
  • Low-profile, integrated spring hinges (select frames)


Fin-Nor sunglasses are designed for serious anglers. We know you're on the water from sunrise to sunset and you need comfort for the long haul. We've worked to reduce the weight of the frame and utilize strategic material placement to provide flexibility where it's needed most. This significantly decreases fatigue and increases comfort, no matter the conditions. In addition, our frames are designed to accommodate a wider range of face shapes and sizes so you can find the perfect fit.

Optimized Performance

Ultimately, our frames are designed to allow our lenses to do their job. With an innovative venting system to increase air circulation, our frames keep fog and sweat from getting in the way. Most Fin-Nor frames also include a built-in top shield and side shields that eliminate unwanted light and help you see clearly. Our minimalist frame design keeps excess material out of your field of vision, so you can search the water for signs of that perfect casting spot.

Glass or Plastic?

The lens material you choose should be decided based on what you want out of your shades. Glass delivers ultimate optical clarity and best-in-class scratch resistance while plastic lenses offer a lighter weight alternative.

At Fin-Nor, we have gone to great lengths to optimize each material, getting the most out of each. So no matter which you choose, you can be confident it has the best technology and engineering of any lens on the planet.
