Polarized

If you have been shopping for designer sunglasses, chances are you probably stumbled on some foreign sounding sunglasses features that have only added up more confusion than shed light. Polarization is among the widely used sunglasses technology but only a handful people actually understand the science behind it. So before you shell out money on an expensive pair of designer sunglasses, it would be beneficial to learn and to help you make the right choice.

You probably heard a lot of outdoor enthusiasts extolling on the virtues of polarized sunglasses. Even athletes have fully benefited on the advantages of such feature sin sunglasses in enhancing clarity and acuity in vision especially in extreme games. Visual focus is a highly critical factor in determining the outcome of the game, and wearing the very best polarized sunglasses in the market would significantly turn the odds to your favor.

So how do these polarized lenses work? Normally the light reflected in a flat reflective object such as the road and a body of water is known to be horizontally polarized. Such refection is generally blocked by vertical polarizers that most lenses have. This ultimately results to the irritating glare that can sometimes pose a serious safety problem, especially when driving. Polarized sunglasses reduce glare effectively by up to 97% from such surfaces that results to better vision and accurate movements that enhances ones performance. So while most people think that they have the best sunglasses when it offers 100% protection from the harmful UV rays, there is definitely more in store.

A close observation at shimmering water would give you an idea how the glare can generally hamper sight from seeing through underwater. The iris of the human eye has a mechanism of narrowing to block out the light from the intense glare. However, such natural body instincts are simply not enough to ward of the harmful bright lights. This brings home the fact that the use of polarized lenses has increasingly become highly imperative.

This innovation was actually long discovered way back in 1936 by Edwin H. Land by conducting a study on the natural path that light travels. He found out that the light actually takes a form of waves that can steadily vibrates into various directions. By using polarized sunglasses, it polarizes the light; in layman’s term it forces the light to simply vibrate in one direction. Among the popular lenses that feature the polarization technology are the CR-39 and the polycarbonates lenses that contain polarization filters within the lens. This filter is manufactured with materials that contain vertically aligned molecules that make it a sufficiently good polarization agent.

When shopping for highly functional sunglasses, keep in mind that polarized sunglasses are considerably more expensive than the ordinary ones that only offer UV protection. Many replica sunglasses claim to have polarized lenses but in truth these are merely false claims. To be able to conveniently check the authenticity of the polarized lenses, simply rotate the lens into the direction of the glare and see if the intensity of the glare changes when looking through the lenses. If you notice the big difference on the glare as seen through naked eye and bespectacled ones, then it is probably authentic. Some people make the mistake of choosing the replicas over the genuine sunglasses that offer more problems. Although you can easily save a few hundred dollars of counterfeit sunglasses, such products are actually known to cause damage to the eye because of the inferior quality of materials used.

So if you demand more from your sunglasses than merely a fashionable accessory then don’t settle for anything less than the original. Granted that they may fetch significantly higher prices, they definitely make a reasonable investment.
