What Are The Best Sunglasses for Outdoor

When you're outdoors, your eyes are exposed to harmful UV rays, glare, and debris. Proper sunglasses can prevent long-term damage like cataracts and macular degeneration. Here's what you need to know:

• UV Protection: Look for sunglasses with 100% UVA/UVB protection (UV400 rating). Dark lenses don’t guarantee UV safety.

• Polarized Lenses: Reduce glare from water, snow, and other reflective surfaces, improving clarity and reducing eye strain.

• Lens Transmission (VLT): Bright conditions need 0–19% VLT; general outdoor use works with 20–40% VLT.

• Durable Frames: Lightweight materials like TR90 thermoplastic or nylon ensure comfort and impact resistance.

• Advanced Tech: NIRTECH® lenses block UV rays and 85% of near-infrared radiation, cutting heat, glare, and eye fatigue. They also improve color contrast and depth perception.

Top Picks:

• Flathead: Best for hiking, with vented frames and lens options for varying light.

• Crater: Ideal for backpacking, featuring sweat-repelling coatings and tough construction.

• Tahoe: Perfect for long trips, offering comfort with slip-resistant frames and versatile lens tints.

Each model costs $109.00 and includes free shipping on orders over $25. Choose based on your activity and light conditions for maximum protection and comfort.

What Is NIRTECH® Lens Technology?

NIRTECH® is a patented nine-layer lens system designed by NINES® Sunglasses to block all UV rays and over 85% of near-infrared radiation (NIR). While most sunglasses only shield your eyes from UV light (below 400 nm), NIRTECH® goes further, protecting against infrared radiation above 760 nm - the invisible heat energy that standard polarized lenses often miss.

Here’s why that matters: dark lenses can cause your pupils to dilate in low-light conditions, which increases your exposure to infrared radiation. This exposure can lead to heat buildup, eye fatigue, and even a higher risk of cataracts over time.

"IR is usually what causes your eyes to feel uncomfortable... you won't notice, but you will feel the heat build up and eye stress caused by the IR." – NINES® Optics

The advanced design of NIRTECH® not only boosts comfort but also improves visual clarity outdoors. Instead of using traditional heat-dipping methods, these lenses feature a low-temperature film coating, ensuring a uniform surface that reduces fogging and light scattering for sharper vision.

Benefits of NIRTECH® for Outdoor Use

The technology behind NIRTECH® lenses is tailored for outdoor enthusiasts. Its polarized layers cut down horizontal glare from reflective surfaces like water, snow, and roads, while the infrared-blocking layers help keep your eyes cool, even during long hours outside [8, 13]. James R., a professional angler from the Florida Keys, shared his experience:

"The clarity is unreal. I fish in the Florida Keys and these lenses cut the glare like nothing else I've tried. After 4 hours on the water, my eyes still feel fresh".

In addition to glare reduction, NIRTECH® enhances both color contrast and depth perception - essential for activities like hiking rocky trails or spotting obstacles in shifting light conditions [12, 13]. The lenses also block between 74% and 96% of high-energy visible (HEV) blue light, depending on the lens color. For example:

• Gray lenses (14% light transmission) maintain true color perception in intense sunlight.

• Chartreuse lenses (43% light transmission) are ideal for low-light settings, offering maximum visibility.

• Deep Blue Mirror lenses (11% light transmission) excel in high-altitude environments, blocking 96% of HEV light.

These features make NIRTECH® lenses a versatile choice for a wide range of outdoor conditions.

Key Features of NINES® Sunglasses

NINES® pairs its advanced NIRTECH® lenses with TR90 thermoplastic frames, which are designed to flex rather than break on impact [8, 9]. Maya S. from Bend, Oregon, praised their durability, noting that her sunglasses stayed "scratch-free" even after a fall during a hike.

The lenses also boast hydrophobic and oleophobic coatings that repel sweat, rain, and skin oils, ensuring clear vision during intense activities like uphill backpacking. Some models even include built-in vent holes in the frames to improve airflow and reduce fogging.

To keep your NINES® sunglasses in top shape, clean them with a microfiber cloth and polarized-safe cleaning spray. Avoid using alcohol or sanitizing wipes, as these can damage the nine-layer coating. Always store your sunglasses in their protective case for safekeeping.

How to Care for Your Outdoor Sunglasses

Taking proper care of your NINES® sunglasses can significantly extend their lifespan. According to Floyd Randle Tibbs, an optometrist at the University of Alabama at Birmingham, "if you take good care of your sunglasses, they can last for 10 years or more". A few straightforward habits can help protect your sunglasses and keep them in great condition.

Start with a rinse before wiping. Dust and debris can scratch your lenses, so always rinse them under lukewarm water first. Add a drop of mild soap to each lens, gently rub the lenses and frames, rinse thoroughly, and dry them with a clean microfiber cloth. Avoid using paper towels, tissues, or your shirt - these materials can scratch the NIRTECH® coatings.

Proper storage is equally important. A hard-shell case offers excellent protection against impacts, especially when your sunglasses are in a bag. If a bulky case feels impractical for activities like hiking, a microfiber pouch provides basic scratch protection. And here’s a big no-no: never leave your sunglasses on your car dashboard. Steve Arbetman, owner of Flight Sunglasses, explains that "extreme heat can be generated by the windshield of your car... That heat can actually cause the lens of your sunglasses to delaminate".

After trips to the beach or water crossings, be sure to rinse your sunglasses. Salt can corrode both metal frames and lens coatings. Stick to lukewarm water to protect the polarization layers, and avoid household cleaners like Windex, rubbing alcohol, or vinegar, as they can damage the advanced lens technology.

Handle your sunglasses carefully to avoid unnecessary wear and tear. Hold them by the bridge to prevent bending, and resist the urge to rest them on your head - this can stretch the frames and transfer oils from your hair onto the lenses. Lastly, keep your microfiber cloths clean by washing them regularly, but skip fabric softeners or dryer sheets, as these can leave behind residues that smear your lenses.

Choosing Sunglasses for Your Activity

Picking the right sunglasses isn’t just about style - it’s about finding the perfect match for your activity, environment, and comfort. With NIRTECH® performance at the core, NINES® sunglasses are designed to provide both premium protection and all-day wearability. Here’s how to make the best choice based on your needs.

Start with light conditions. If you’re heading to high altitudes or desert landscapes, darker lenses like Gray or Deep Blue Mirror are your best bet. They offer strong protection while maintaining natural color perception. For low-light situations - think dawn, dusk, or shaded forests - Chartreuse lenses are ideal for keeping visibility sharp. And if you’re dealing with variable lighting, go for Light Blue Mirror or Amber lenses, which not only adapt well but also enhance contrast.

Consider the terrain. For water-based activities like fishing or kayaking, polarized lenses are essential. They cut through surface glare and improve underwater visibility. If you’re tackling snowy trails or high-altitude climbs, Deep Blue Mirror or Gray lenses handle intense reflections with ease. On rocky or forested paths, Amber lenses are an excellent choice - they sharpen depth perception, making it easier to spot roots, rocks, and uneven surfaces.

Think about the intensity of your activity. For high-energy pursuits like trail running or steep climbs, look for models with vent holes and moisture-repelling coatings to stay comfortable and fog-free. On longer backcountry adventures, NIRTECH® technology shines by blocking up to 85% of near-infrared radiation. This helps reduce eye strain, heating, and fatigue.

Of course, lens selection isn’t the only factor. A proper fit and durable design are just as important. NINES® frames, made from TR90 thermoplastic, flex comfortably to your face and can handle drops or rough handling without a hitch. If you’re wearing a helmet for cycling or mountaineering, ensure the sunglasses fit snugly without causing discomfort or interference.

All polarized NINES® models come with NIRTECH® technology and are priced at $109.00, offering premium protection at a solid value. Match your sunglasses to your main activity and typical conditions to get the most out of your outdoor adventures.

Conclusion

When selecting sunglasses, prioritize those that offer 100% UV protection, polarized lenses to cut glare, and the ability to filter near-infrared (NIR) light - something standard lenses often miss. While UV400 protection is the baseline, NIRTECH® lenses take it further, blocking up to 85% of NIR light, which can cause eye fatigue and long-term damage. This added layer of defense is designed to keep your eyes safe and comfortable, no matter where your adventures take you.
