In 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 Work

When 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. Polarized lenses decrease visual contrast, which means they make it harder to distinguish shapes in the snow, like snow patches and other hazards.

Also, liquid crystal display, or LCD, screens become invisible when viewed at a certain angle through polarized sunglasses. Today, LCDs are commonly used in new ATMs and in-dash navigation systems on cars.

But aside from these instances, polarized sunglasses are a great tool to have handy. They come in all different kinds of style, so you can be sure to find a pair that you like. Photochromic polarized lenses are especially good for light-sensitive eyes. These lenses change from dark shades when outside to light shades when indoors. Whether you’re an avid golfer, biker, jogger, or simply like (or have to) spend a lot of time outdoors, try upgrading your glasses to polarized shades.
