Your activity match

Remote water and high exposed routes demand detail close to the line and far across the terrain.

A high-lake day can combine a long approach, rock or snow glare, map checks, water texture, and line movement. Hexachroma supports terrain, screens, and fine detail; TVO Pro is the focused polarized route for hard glare.

The four issues that matter most across your two activities

We selected two high-priority issues from each activity. Open any card to see how 2nu addresses it.

01

Surface glare hides line and water detail

Strong reflections can hide fishing line, floats and movement near the surface, while making long periods of observation more tiring.

How 2nu solves it

Use polarization to control reflected glare

TVO Pro controls strong surface glare. Choose flagship Hexachroma when you also want higher contrast, more outdoor detail and better screen readability.

02

Exposed snow and rock create hard glare

Above the treeline, direct sun and reflected light can remain intense for long sections with little natural shade.

How 2nu solves it

Start with ALPINE-rated glare control

Every 2nu sunglass lens provides UV400 protection. For sustained exposed glare, start with the deeper blue- or gold-mirror configurations that rank strongly on the ALPINE axis, then choose TVO Pro or Hexachroma by detail and screen needs.

03

Polarized lenses can darken screens

A fish finder, phone, camera or watch can appear dark at certain angles through some polarized lenses.

How 2nu solves it

Hexachroma keeps screens easier to read

Hexachroma maintains polarized glare control while helping reduce the common screen blackout problem. Results still vary by screen type, polarization direction and viewing angle.

04

Rock, snow and shadow detail changes quickly

Terrain can move from bright snow or pale rock into deep shadow, making surface texture and route cues harder to separate.

How 2nu solves it

Keep terrain detail in the decision

TVO Pro focuses on strong polarized glare control. Hexachroma is the flagship option when you also want higher outdoor detail and easier separation across exposed and shaded terrain.

How we choose

Balanced for Fishing + High Mountain Trekking

We compare brightness and changing light, colour and contrast, reflected glare and screen use, and frame performance across both activities—then rank the strongest overall balance.

Fishing

Reflected-glare control and clearer detail over long hours.

High Mountain Trekking

Stronger light control and coverage for exposed high-altitude conditions.

Questions before you choose

Use these answers to compare the lens, frame and conditions that matter across your selected activities.

01Should I choose Hexachroma or TVO Pro for fishing?

Both are polarized and control reflected glare from the water. TVO Pro is the focused choice for strong glare control. Choose flagship Hexachroma when you also want higher contrast, more outdoor detail and better readability on a fish finder, phone, camera or watch.

02Why start with deeper blue- or gold-mirror configurations for ALPINE conditions?

Above the treeline, direct sun and reflected light can remain intense for long sections with little shade. Deeper blue- or gold-mirror configurations are the starting point for sustained exposed glare; compare the ALPINE radar and the exact lens option rather than choosing by colour alone.

03Why can polarized lenses darken a fish finder, and how does Hexachroma help?

The polarization direction of a screen can interact with a polarized lens, making the display look darker at certain angles. Hexachroma helps maintain screen readability better than many polarized lenses while still controlling glare. Screen type and viewing angle will still affect the result.

04How do I compare fit for wind, climbing movement and long wear?

Use the frame-coverage and head-fit information in each product callout. On a FlexFoam™ frame, adjust it by hand first, then wear it for about five minutes so FlexLock™ can distribute support around the head instead of relying on one tight pressure point.
