Lens

UV400 protection blocks UVA and UVB rays up to 400 nm, the range most relevant to daily outdoor sun exposure. It is the baseline protection in 2nu sunglasses, so your eyes are protected while the lens technology handles glare, contrast, and comfort.

Polarized lenses reduce strong reflected glare from water, glass, wet roads, and other bright surfaces. They are useful outdoors, but typical polarized lenses can sometimes make phone, watch, dashboard, or navigation screens black out or look uneven.

Hexachroma™ is 2nu’s outdoor light-management lens technology. Typical polarized lenses mainly reduce glare from one direction. Hexachroma™ is tuned to manage more complex outdoor reflections from seawater, wet roads, metal grates, glass, and concrete, reducing harsh glare while keeping road texture, water layers, shadow detail, and colour contrast easier to read. The goal is not to make everything darker; it is to keep vision clearer, steadier, and more natural outdoors.

Metonic Coating forms a protective layer over the mirrored lens finish. It withstands seawater, sweat and oil exposure for 48 hours, helping reduce coating peel-off and delamination and improve durability during repeated outdoor use.

FlexFoam™

FLOAT MAX is built for water use. The frame is designed to stay afloat if dropped in water, helping reduce the chance of losing your sunglasses during paddling, boating, beach training, fishing, or water sports.

Prescription lenses are made to order from your vision details. Choose the frame and lens option first, then enter your prescription at checkout or send it later by WhatsApp or email. Production starts after the details are confirmed.

FAQ

FlexFoam™, clearly explained.

Three practical answers before you choose your frame and lens setup.

What is FlexFoam™?

FlexFoam™ is 2nu’s non-hollow, lightweight and flexible frame system. It can be adjusted by hand and is designed to float in seawater.

Is Floatanium the same as FlexFoam™?

Yes. Floatanium was the earlier name for the same frame technology. FlexFoam™ is the current name.

Does every FlexFoam™ setup float the same way?

No. Standard non-prescription FlexFoam™ configurations are designed for seawater buoyancy. Hexachroma options marked FLOAT MAX provide 2nu’s strongest floating performance. Prescription lenses add weight and can affect buoyancy.
