Three Lens Options, One Dependable Matte Black Frame

The Nitro polarised is a square matte black frame that covers the bases without overcomplicating things. Polycarbonate construction keeps it light for daily wear, the square shape suits a wide range of face types, and three lens options give you enough choice to pick based on how and where you wear your shades most. Red mirror brings warmth and contrast in full sun, blue mirror is a clean classic for on-water and open-sky conditions, and dark grey is the most versatile of the three — subdued enough to work in changing light throughout the day and serious enough for full NZ sun when it matters.

The matte black finish ties all three lens options together cleanly. It's a frame that sits comfortably across different settings without looking like it belongs exclusively to the sports category or the lifestyle one.

Category 3 polarised lenses for high sun conditions.

Polarised Lenses

New Zealand sun is some of the most intense in the world, and standard tinted lenses only solve part of the problem. They darken the view but leave the glare. iPOP polarised lenses have a built-in glare-filtering layer that targets the specific type of light that causes the problem in the first place.

How polarised lenses work

Glare happens when sunlight bounces off a flat surface, water, wet roads, a car bonnet and hits your eyes as a concentrated horizontal beam. Your eyes struggle to process it, so you squint, strain, and lose visual detail in the process. Polarised lenses block that horizontal light before it reaches your eyes, so surfaces become readable again rather than a wall of reflected brightness. On a typical New Zealand summer day, the difference is noticeable within minutes of putting them on.

Where it makes a real difference

Driving Cuts glare off wet roads and oncoming windscreens so you're not squinting into the morning sun

Fishing and water See below the surface instead of staring at a mirror of reflected sky

Beach and outdoors Reduces the all-day eye fatigue that builds up when everything around you is reflecting light

Sport and activity Sharper contrast and truer colours so you can read terrain, track movement and react faster
