The Advantages of Polarized Sunglasses
The Advantages of Polarized SunglassesAuthor: Ryan FrankIn recent years, polarized sunglasses have become very popular amongst joggers, golfers, bikers and other outdoor sports enthusiasts. Polarized sunglasses were initially used by fishermen and boaters in order to block the at-times intense glare caused by the sunlight reflecting off the water surrounding them. But it’s not only outdoors sportspeople who can benefit from this technology. Anyone who spends a lot of time in the sun can use a little less glare. People who drive a lot, especially, can benefit from using polarized sunglasses, since they are made specifically to ward off glare coming from long, flat surfaces, like roads. Also, people who are sensitive to intense light of any kind, like post-eye-surgery patients, can use polarized sunglasses indoors to prevent injury. How Polarized Lenses WorkWhen light is reflected off horizontal, flat surfaces it becomes horizontally polarized. Polarized lenses are made to be vertically oriented so that they deflect horizontally polarized light rays.
This means that glare from light reflected off flat surfaces is greatly reduced. One of the areas in which the benefit of polarized sunglasses is still being disputed, however, is their use in snow settings. Snow sports practitioners can take advantage of the lenses’ glare reduction, but some experts argue that using polarized sunglasses, especially while participating in high-speed snow sports like skiing, can be dangerous.
