Hexachroma 2nu flagship polarized lens system

Lens clarity for real outdoor use

Clarity when light keeps changing.

Hexachroma is built for glare, contrast, and quick screen checks across road, trail, water, driving, and daily outdoor movement.

Changing light Road / water / glass glare Phone and watch readability

Why it matters

Clearer decisions when the view keeps shifting.

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

Built for the reflections that show up outside.

Road

Wet asphalt and bright lanes

Helps take the edge off reflected light so surface changes are easier to read while moving.

Water

Sea glare and bright chop

Useful near coastlines, boats, beaches, and open water where reflections shift constantly.

Glass

Windows, cars, and dashboards

Helps calm hard reflections from glass and vehicle surfaces during driving and daily use.

Trail

Shade-to-sun contrast

Keeps the view steady when trees, clouds, and open ground change the light quickly.

Hexachroma lens view with phone and watch visibility

Screen-friendly polarized clarity

Polarized glare control without fighting every quick check.

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

One lens system for the places 2nu is built around.

Running

For road glare, changing shade, and watch checks during pace changes.

Hiking

For trail contrast, open ridgelines, and bright surfaces after rain.

Water

For sea glare, reflective decks, and long hours around coastlines.

Driving

For dashboards, glass reflections, wet roads, and strong afternoon light.

Daily outdoor

For phone maps, bright pavement, cafe windows, and regular sun exposure.

Recommended Hexachroma frames

The simple version

Less glare. Useful contrast. Easier checks.

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

Practical questions about Hexachroma.

Is Hexachroma polarized?

Yes. Hexachroma is 2nu's flagship polarized lens system, made for outdoor glare control and practical visibility.

Will Hexachroma make phone and watch screens easier to see?

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.

What kind of glare does it help with?

It helps reduce harsh reflected light from common outdoor surfaces such as wet roads, water, glass, bright pavement, vehicle panels, and pale ground.

Is Hexachroma only for water sports?

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.

Which Hexachroma frame should I choose?

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.

面對熱帶高溫、海水鹽霧與防曬霜的挑戰，一般鏡片往往不得不妥協。但 2nu 選擇正面迎擊。
我們獨家研發的 Metonic™ 鍍膜 能在鏡片表面形成一道強效的疏水疏油保護盾。這意味著水珠遇上即瞬間滑落，指紋油污一抹即淨，更有效阻隔鹽分侵蝕，確保視野不受干擾。
💧 強效排斥： 隔絕潮濕水氣、劇烈運動後的汗水及皮膚油脂。
🛡️ 堅固抵禦： 對抗海水腐蝕及日常微細刮痕，延長鏡片壽命。
👁️ 極致視野： 無論是穿梭於濕熱的城市街道，還是征服崎嶇的海岸山徑，視野始終清晰鋭利。

When losing your sunglasses isn’t an option, this is the one.

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.

浮力，源於細節。Hexachroma 系列採用了 超輕量鏡片技術 (Ultra-Lightweight Lenses)，從根源減輕重量，提供比一般浮水眼鏡更優越的浮力表現。
鏡片更輕： 在保持高清晰度與防撞保護的同時，大幅降低整體重量。
浮力升級： 經測試證實，在水溫 32°C 以下 的海水中依然能保持漂浮。
專業提示： 即使在密度較低的暖水海域（如熱帶衝浪點），Hexachroma 依然能為你提供最可靠的防沉保護。

我們的鏡框採用創新材質 FlexFoam™ 製成，具備輕盈、柔軟且極具彈性的特性，提供卓越的舒適度與貼合性。
雖然我們主要推薦給一般頭型的使用者，但 FlexFoam™ 的獨特可調性，讓它能自然貼合各種頭型尺寸。與傳統鏡框需依賴精確尺寸不同，FlexFoam™ 能靈活調整，即使您的頭型偏大或偏小，也能享有穩固舒適的配戴體驗。
