You have probably heard of and have come across the term ‘Polarized Sunglasses’ before. If you are wondering what they actually are, and how are they different from the other sunglasses in terms of their sun-protection factor, then below is some information that will clear all your doubts. Why Should One wear Polarised Lenses? Polarised lenses help to reduce glare that is caused when the light from the sun is reflected off certain surfaces such as water, glass, and roads. These lenses help you look at these surfaces more comfortably, and see them more clearly by preventing the glare from reaching your eyes. As a result, you don’t suffer from painful headaches, nausea, fatigue in the eyes, or even short-term blindness. What is polarised light and polarised glare? Light from the sun travels in the form of waves and in many directions. Polarised light is a group of light waves that move along the same plane, and travel parallel to each other. The group of polarized light waves that is reflected off a horizontal surface travels in the horizontal direction, and composes the polarised glare. In order to block the polarised glare that makes it difficult for the human eye to view objects comfortably, it is imperative that one wears sunglasses with polarised lenses. These lenses have a chemical filter that blocks all the horizontally concentrated light, and allows only the vertical components of the light rays to pass through, thereby eliminating glare. When should one wear polarised sunglasses? Although everyone should wear sunglasses with polarized lenses since glare can be straining for their eyes, there are a few activities and professions that demand such sunglasses the most. If you are out fishing, then put your polarized sunglasses on, and you will be able to see through the surface of water more clearly. Skiers can have a better experience while wearing such sunglasses as they will be able to see the bumps in the snow that are otherwise invisible. Make sure you wear your pair of polarized sunglasses while driving, so you will not be affected by the sun’s glare that is the cause of many accidents. Types of polarised lenses There are two major variants of polarised lenses available in the market today - .75 mm and 1.1 mm. Although the first variant is made from thin sheets of film, it is more than sufficient to keep the glare away while one engages in activities such as golf. The second variant is designed with thicker sheets of film, and is apt to tackle glare, along with high-impact resistance. This feature makes this type of sunglasses an ideal option for fisherman, skiers, and other water enthusiasts. Where can you buy polarized sunglasses from? Many e-commerce companies sell a variety of polarized sunglasses on their online portal. You can browse through the product offerings by brands such as IDEE, Ray-Ban, Fastrack, Lee Cooper and many others. They are designed with different lens types, frame colors, and are sold at different prices. Choose the one that you think best suits your face, pay for it online or offline, and get it delivered to an address of your choice.
