In addition to blocking blinding glare, polarized lenses can also help you to see better by improving contrast and visual comfort, and acuity.
When we spend time outdoors, glare and reflections are literally all around us, even bouncing off particles in the air. When we remove all this unwanted “visual noise” by putting on a pair of polarized lenses, our vision is improved beyond just removing dangerous blinding glare.
Color and depth perception is improved, along with clarity and contrast of objects. Photographers have known this secret for years and often use polarizing filters to achieve bolder colors and deeper contrast in their photographs (in addition to removing glare, of course).
Depending on the color you choose for your polarized lenses, color and depth perception may be enhanced even more. For instance, copper highlights reds and greens and is the preferred color for driving.
