The Benefits of Polarized Sunglasses

polarized-lens-vs-non-polarized-lensPolarized sunglasses were initially worn by fishermen and boaters. When they first tried them out they were delighted to find that this special type of lens meant that the glare coming from the water’s surface was less dangerous to their eyesight. Ever since, the sales of polarized sunglasses have skyrocketed as they have been proved to help a huge number of individuals who pass their time outdoors. These include cyclists and motorbike riders, nature lovers and hikers, and other sports enthusiasts such as joggers and golfers. All these categories of users are able to eliminate glare and attain a clearer view. Another considerable benefit of polarized sunglasses is that whoever wears them is able to drive a car or other types of vehicles without suffering from the reflection given by metallic hoods or even the stretch of road ahead of them.

Medical Uses

Anyone who suffers from light sensitivity can find this form of polarized sunglasses very beneficial, and they can even wear them indoors, as the exposure to certain types of lighting can be very uncomfortable. They are also ideal for individuals who have specific eyesight conditions (one prominent example would be U2’s Bono), as well as for patients who have undergone cataract surgery and are vulnerble to glare and light.

The Way Polarized Lenses Work

Generally speaking, when there is a reflection of light from certain surfaces including calm water or a flat road, it is polarized in a horizontal fashion. As a result, rather than the usual scattering out of light in every direction, this generates a strong glare that can be dangerous due to the intensity. At best, it can be very annoying. In order to counteract these unpleasant effects, a unique filter is added to the make-up of the polarized lenses. This serves to block out this reflection and considerably lessens the discomfort.
