What Are Polarized Lenses?
As the sunlight scatters everywhere but when t hits a flat surface, it reflects the light. Also, the light tends to become polarized. It means that the beams of reflected light travel in a uniform direction.
Eventually, it creates an irritated and sometimes dangerous intensity of light and causes glare and reduced visibility.
Polarized sunglasses will provide you superior glare protection, especially on the water. Polarized lenses possess a special filter that blocks intense reflected light and reduces glare and discomfort.
Though these sunglass lenses boost comfort and visibility, you may encounter some moments when these lenses are not advisable. One of the examples is downhill skiing, where you actually want to see the bright patches of reflected light as they alert you to icy conditions.
Besides, polarized lenses decrease the visibility of images created by liquid crystal displays (LCDs) present on some digital screens, such as bank automatic teller machines (ATMs) and gas station pumps.
With polarized lenses, you also may find it harder to see the screen on your phone.
Advantages Of Polarized Sunglasses
When it comes to reducing eye strain and discomfort in bright sunlight, polarized sunglasses provide great advantages.
A polarized lens offers the following advantages over non-polarized lenses:

If you are one of those people who concern about enfeebling sunlight and glare, then polarized sunglasses are the best choice. However, there are some people who cannot wear them.
The reason can be neurological or psychological, there are some people who say that lenses make them feel disoriented and dizzy. While some insist that they generate an artificial 3-D effect.
For such a subset of individuals, it is possible that the photoreceptor cells present at the back of their eyes catch the vertical light signals differently than the rest of the people. In such circumstances, tinted lenses can be the best option.
There are also some occupations that require a worker to be able to read specific digital numbers on a liquid crystal display. Sometimes, a polarized lens can interfere with the visibility of the numbers and you should avoid them.
