The Difference is Clear
Originally developed for boaters and fishermen who needed to reduce glare coming from the surface of the water, polarized lenses have come to the forefront of sunglass lens technology. If you’ve ever worn them outdoors, you probably noticed polarized lenses not only reduce glare, but they also provide a more clear-looking field of view.
It’s not just outdoor enthusiasts who can enjoy the benefits of a polarized lens. Glare from a car hood or from a long, flat road can be avoided with the use of polarized lenses. In fact, they can even help indoors for post-cataract surgery patients or by those who may be sensitive to light.
So How do They Work?
The light that hits our eyes is usually being scattered in many different directions by the surfaces and objects around us. However, the light that has been reflected from a flat surfaces is usually horizontally polarized. This means the light is traveling in a direction that’s more or less horizontal to our line of sight. It’s this horizontal reflection that we experience as glare.
Polarized-2A polarized lenses contain a special filter that blocks light from horizontal reflections, allowing you to view your surroundings without the glare. This provides a more comfortable experience with far more visibility than with traditional lenses.
While polarized lenses make LCD and LED displays a little more difficult to read, for most people who spend time outdoors, the benefits of polarized lenses outweigh the few drawbacks.
