Lens Difference | TVO, TVO Pro & Hexachroma

Choose lenses by how you actually use your sunglasses outside

2nu sunglasses are built for outdoor performance, so lens choice is not just about tint colour. The right lens should protect with UV400, manage glare, keep vision clear in changing light, and stay practical when you need to check a phone, watch, dashboard or map.

If you run, hike, fish, drive, train near water or spend long hours outdoors, start with the environment first: bright road glare, sea reflection, sweat, screens, and how long you will wear the sunglasses.

Quick answer: polarized, UV400 and clarity are different jobs

UV400 is about blocking ultraviolet light. Polarized lenses are about reducing harsh reflected glare from roads, water, glass and bright surfaces. Lens clarity is about how natural and usable the view feels after the glare is controlled. A good outdoor sunglass lens should balance all three.

2nu lens options at a glance

• TryOn lens: for real-world fit testing before buying. It helps you test frame size, comfort and stability, but it is not the same premium lens setup as the final sunglasses.
• TVO: a practical outdoor lens option for everyday clarity, lightweight wear and UV400 protection.
• TVO Pro: a stronger polarized option for glare control when reflection from roads, water or bright surfaces becomes a bigger issue.
• Hexachroma: 2nu’s advanced polarized lens option for shoppers who want stronger glare control with more practical phone, watch and display visibility outdoors.

Which lens should you choose?

• Running: choose a lens that keeps vision stable under sweat, bright roads and quick watch checks. See running sunglasses.
• Hiking: choose clarity and comfort for open trails, shaded sections and long wear. See hiking sunglasses.
• Water sports: prioritize glare control, UV400 protection and resistance to seawater conditions. See water sports sunglasses.
• Phone and watch visibility: if screen readability matters, compare Hexachroma before choosing.

Frequently asked questions

Are polarized lenses the same as UV400?

No. UV400 protection blocks ultraviolet light. Polarization reduces reflected glare. They solve different problems, so outdoor sunglasses should be evaluated for both protection and usable vision.

Do runners need polarized sunglasses?

Not every runner needs polarization, but it helps when glare from roads, concrete, water or glass makes the view harsh. Fit, weight, sweat stability and screen checks still matter.

Can polarized sunglasses make screens harder to read?

Some polarized lenses can darken or distort screens at certain angles. If phone, watch, car or marine display visibility is important, consider the lens option designed for more practical screen checks outdoors.
