How Do Polarized Lenses Reduce Glare?

Polarized lenses have always been widely used by fishermen and crews, given the need to reduce the reflected brightness of the surrounding water.The trend has spread to many other professions that involve spending a lot of time outdoors, namely:

  • Skiers
  • Cyclists
  • Golfers
  • Practitioners of jogging

This type of lenses are also very useful for those who drive. These lenses reduce the reflected brightness of long, flat surfaces, such as the road surface or the roof of a car. People with a high sensitivity to light, including patients undergoing cataract surgery, are other users of polarized lenses.

How do polarized lenses work?

The light reflected from flat surfaces, such as a road or water, is polarized horizontally.It means that instead of the light scattering in various directions, it is directed horizontally, which creates an uncomfortable and sometimes dangerous light intensity, which we call the brightness.

This type of lens reduces the reflected brightness of roads, streams, snow and other horizontal surfaces.These lenses make the eyes feel more comfortable and, consequently, see better.

The special polarized lens filter blocks this type of intense reflected light, reducing brightness. Therefore, these lenses improve the comfort and visibility of its users. Sunglasses with bifocal or progressive polarized lenses are one of the best examples of options to correct presbyopia for outdoor enthusiasts.

In contrast, color-changing photochromic lenses depending on whether they are inside or outside doors, darkening outdoors and brightening indoors may be excellent for people with a high sensitivity to light that often oscillate their activity within and out of doors.
