Lens clarity for real outdoor use
Hexachroma is built for glare, contrast, and quick screen checks across road, trail, water, driving, and daily outdoor movement.
Why it matters
Outdoor light rarely stays even. A run can move from shade to sun in seconds. A wet road can throw glare back into your eyes. Water, glass, pale concrete, and vehicle panels can all make the view feel busy.
Hexachroma is 2nu's flagship polarized lens system because it focuses on that practical middle ground: reducing harsh reflected light while keeping contrast and everyday visibility useful.

Common glare problems
Helps take the edge off reflected light so surface changes are easier to read while moving.
Useful near coastlines, boats, beaches, and open water where reflections shift constantly.
Helps calm hard reflections from glass and vehicle surfaces during driving and daily use.
Keeps the view steady when trees, clouds, and open ground change the light quickly.
Screen-friendly polarized clarity
Typical polarized lenses can make some phone, watch, and dashboard screens look dark or uneven at certain angles. Hexachroma is tuned to keep those quick outdoor checks easier while still giving you polarized glare control.
Screen behavior can still vary by device, brightness, and angle. The point is practical readability in normal outdoor use, not a promise that every display looks identical.
Where it fits
For road glare, changing shade, and watch checks during pace changes.
For trail contrast, open ridgelines, and bright surfaces after rain.
For sea glare, reflective decks, and long hours around coastlines.
For dashboards, glass reflections, wet roads, and strong afternoon light.
For phone maps, bright pavement, cafe windows, and regular sun exposure.
Recommended Hexachroma frames
Hexachroma is available across selected 2nu outdoor frame shapes. Start with the fit and coverage you want, then choose the lens colour that suits how you use it.

The simple version
Hexachroma is not about making the outdoors look artificial. It is about helping the view feel calmer and more readable when light, surfaces, and movement keep changing.
FAQ
Yes. Hexachroma is 2nu's flagship polarized lens system, made for outdoor glare control and practical visibility.
It is designed to be more screen-friendly than many typical polarized lenses, especially for quick checks outdoors. Some displays can still shift with angle, so device brightness and screen type still matter.
It helps reduce harsh reflected light from common outdoor surfaces such as wet roads, water, glass, bright pavement, vehicle panels, and pale ground.
No. It is useful for water, but also for running, hiking, driving, and daily outdoor use where glare and changing light are part of the day.
Choose by fit and coverage first. Fancy has a classic Wayfarer-style frame, Halo has a round frame shape, and Zealot gives wider coverage for movement.

UV400 protection ensures that sunglasses effectively block 100% of harmful ultraviolet (UV) rays, including both UVA and UVB, up to wavelengths of 400 nanometers. This advanced level of protection helps safeguard the eyes from prolonged sun exposure, reducing the risk of conditions such as cataracts, macular degeneration, and other UV-related eye damage.
Standard lenses surrender to tropical heat, salt spray, and sunscreen. Ours fight back.
Our proprietary Metonic™ Coating creates a hydrophobic and oleophobic shield on the lens surface. This means water beads up and rolls off, fingerprints wipe away with a single swipe, and salt spray doesn't get a chance to eat into your vision.
FlexFoam™ × FlexLock™
Engineered for movement. Built for extremes.
FlexFoam™ delivers weightless, all-day comfort that stays effortless once you’re moving. Inside, FlexLock™ features hand-adjustable temples, giving you a secure, personalised fit that holds when conditions get demanding. From trail runs to open-water rows, they stay locked in—no slipping, no distractions.
Seawater Buoyancy Index (SBI)
We rated, not guessed.
Prescription (RX) Note
Corrective lenses add weight, which means RX sunglasses will not float. Physics wins.
For seawater sessions, pair RX models with a floating strap and stay focused on the adventure ahead.
Gravity is the enemy. That’s why the Hexachroma Series is built different.
By using Ultra-Lightweight Lens Technology, we reduce weight where it matters most—at the lens. Less weight means higher buoyancy, giving Hexachroma frames a clear advantage over standard floating eyewear.
Ultra-Light Lenses
High-impact protection with a fraction of the weight.
FLOAT MAX Buoyancy (Hexachroma Only)
Our highest floating configuration, engineered to stay on the surface in all seawater conditions.
When control, visibility, and recovery matter, FLOAT MAX delivers.
Pro Tip
Some floating frames lose effectiveness as conditions change.
Hexachroma with FLOAT MAX is designed to stay afloat when the water gets unpredictable—so you stay focused on the session, not your gear.
This is our most versatile cut, designed to fit 90% of face shapes and head sizes. If you typically buy "standard" size hats or glasses, these are your perfect match. While the measurements differ slightly, both utilize the elasticity of FlexFoam™ to ensure that even if you have a slightly wider face, the temples will gently expand to hug your head comfortably all day long.

Designed with a slimmer profile, the Halo is perfect for normal to narrower faces or teenagers. It provides a snug, secure wrap that stays put during high-intensity movement. Don't worry about it being "too small" — the softness of FlexFoam™ ensures it simply hugs your head tighter for stability, rather than squeezing it.
