    • UV Protection, Polarized & Non-Polarized Lenses Explained

    ☀️ UV400 Protection Comes First

    All Knockaround lenses sold in Australia offer UV400 protection, blocking 100% of harmful UVA and UVB rays.

    That's the part that protects your eyes. Everything else is about how you see.

    🕶️ What Polarization Really Does

    Polarization reduces glare caused by light reflecting off flat surfaces like water, roads, and sand.

    It does not protect your eyes from UV on its own — UV protection must be added separately.

    For some activities, polarization is great. For others, it can actually get in the way.

    Why Many Athletes Choose Non-Polarized Lenses

    Here is why cyclists, runners, and golfers often choose non-polarized lenses — even though they still get full UV400 protection.

    🚴‍♂️ Cycling

    Why non-polarized works better

    • Preserves surface detail on the road (cracks, gravel, oil slicks).
    • Better depth perception when descending or cornering at speed.
    • Easier to read bike computers and phone screens.
    • More natural contrast when light constantly changes (trees, buildings, clouds).

    Why polarized can be a drawback

    • Can flatten visual cues on concrete and bitumen roads.
    • Makes shiny hazards less visible.
    • Can distort LCD displays.

    👉 Non-polarized + UV400 = safer, more predictable vision

    🏃‍♂️ Running

    Why non-polarized works better

    • More natural contrast when scanning terrain.
    • Better perception of uneven ground, roots, curbs, and shadows.
    • Less visual disconnect when moving quickly through mixed light.

    Why polarized isn't ideal

    • Can over-reduce glare that helps define texture.
    • Sometimes causes eye fatigue due to unnatural light filtering.

    👉 Runners benefit more from clarity and depth than glare elimination.

    ⛳ Golf

    Why non-polarized works better

    • Maintains true green reading (grain, slope, moisture).
    • Preserves ball tracking in flight.
    • Better contrast between fairway, rough, and fringe.

    Why polarized can hurt performance

    • Removes subtle reflections that indicate green speed.
    • Can make the ball harder to track against the sky.

    👉 Many pros avoid polarization for visual accuracy.
