Polarized sunglass lenses

Polarized sunglass lenses have a filter inside the lens that block out horizontally polarized light–the light associated with harsh glare.

Polarized lenses are great for decreasing squinting and overall eye fatigue from sun and glare.


Who are polarized lenses ideal for?

Everyone. But particularly important when:

  • Driving on a shiny and/or wet road
  • Driving in general
  • Spending time around water (ie. fishing, boating, on a beach, etc.)
  • Spending time around snow (ie. winter, with or without snow sports)

The result? Richer colours and contrasts, less squinting, less eye strain, and safer driving for an all-round more enjoyable visual experience.

How do they work?

There’s a lot of geeky science here, so let’s just skip to the basics:

  1. When light reflects off of a shiny surface (like the road, or snow), it becomes “polarized”.
  2. Our eyes can’t detect this hidden polarizing effect, but we can create a filter against it.
  3. With horizontally polarized light filtered out, the sources of harsh light and glare (horizontal surfaces) are eliminated.

Fun fact:

Polarization of light is thought to be detectable in bees, helping them to navigate over long distances.
