One can't imagine going outside without equipping the sunglasses. Outdoor activists, cyclists, mountaineers and golfers swear by the protection offered by the sunglasses. However, regular piece of a sunglass simply can't withstand the glare reflection and one can't see things when in full bright sun.

For many years, fishers and boatmen have used a special kind of sunglasses which allow them to see through the vast sea waters even when there is a tremendous amount of glare. These are called as Polarized Sunglasses. These days, more and more people are opting for the same due to the additional advantage offered by them BESIDES the usual eye-protection. Skiers, joggers, bikers are thus the natural customers of the same. Let us find out the technology behind these wondrous creations.

Apart from mere protection from light and glare, specialized polarized sunglasses have entered the market. One of them is known as Polarized ‘progressive lenses’ which are perfect for someone who is suffering from presbyopia, but is outdoor enthusiast. For someone whose eyes are sensitive to light, polarized ‘photo chromic lenses’ is the ideal solution. They dynamically change from dark-outside to light-inside. This helps when you change your environments too frequently and the amount of light intensity differs too drastically.

There is some debate over how much the polarized sunglasses actually prove useful for surfaces covered with snow. As snow too is a smooth surface it reflects a great amount of light and thereby can hamper the visibility in an environment fully covered in snow. A group of experts argue that like other environments, polarized sunglasses will reduce the glare and will improve the visibility. Other group says that they have a disadvantage of not providing enough contrast and therefore they may not be beneficial for skiers. The eye cannot distinguish between patches of ice and moguls due to the poor contrast. This can prove dangerous, especially in somewhat low light conditions.

These days, many sunglasses claim to be polarized but in truth they are not. There is a simple test which will enable you to determine the claim. Find any surface which is reflective (bonnet of a car, for example) and look towards it through one of the polarized lenses. Then, slowly rotate the glasses to an angle of 90 degrees, while continuously observing the degree of reflection. If the glasses are indeed polarized, you should see a significant reduction glare as you rotate the glass. If such is not the case, then you have been min-informed.

When purchasing a polarized sunglass, look out for additional feature such as scratch-resistance coating. This is essential when you plan to go for hiking. If your main outdoor activity revolves around water, investing in special swimmers polarized sunglasses makes sense.
