What Are Polarized Sunglasses And How Do They Work?

Polarized sunglasses look cool. Thatโ€™s a fact. Many people that purchase them love the look because it is sporty and modern. However, they are much more useful than just an attractive pair of wayfarer sunglasses. They can reduce eye strain, protect your eyes from UV rays and keep you safe in hazardous conditions. They are no longer sporty styled sunglasses like they used to be back when only fishermen wore them. Now, they come in a wide variety of shapes, sizes and colors for both men and women. There is such a huge selection that it may be helpful to get a little background information on them before you make your purchase.

What are Polarized Sunglasses and how do tsunglashey work?
You may think, as many do, that all sunglasses are created equally. That is not the case. Polarized sunglasses are much different from simple, dark clubmaster sunglasses. They have an element of protection and clarity that other sunglasses simply do not offer. How is this so? First, you will need to understand a little bit about light and what happens when humans see light.

Light has many interesting properties. It is a fascinating scientific phenomenon. When reflected from another surface, light can do all kinds of amazing things. However, the things that may be interesting to scientists can be dangerous if you are trying to drive or play a sport. Polarized sunglasses use one of lightโ€™s properties, known as polarization, to their advantage.

To put it simply, when you are looking at light that is NOT reflected off of a surface, that light source produces waves in all directions, up and down and left and right. However, when light is bounced off of a reflective surface like glass, water, snow or a mirror, those light waves polarize. This means that the light waves orient horizontally along an axis. To your eye, this appears as glare. A polarized sunglass lens orients vertically and reduces the brightness of the horizontal waves. This keeps your vision clear and allows optical information through without interference.

Polarized sunglasses are designed with one purpose. They reduce glare. When you are looking at, or are near, reflective surfaces such as glass, snow or water you may experience a very annoying and intense glare. This can be not just annoying but also dangerous. Polarized sunglasses allow you to see more clearly while boating, driving or participating in sports so that you are safe and able to avoid hazards. They are also preferable because they block out only glare. They do not make your entire field of vision darker. That, in and of itself, can be hazardous in many instances.

Why should you use Polarized Sunglasses instead of traditional tinted sunglasses?
You may be wondering if there really is any need for polarized sunglasses. Tinted sunglasses will reduce brightness and, for some people, that may be all that you need. However, they will not remove annoying and sometimes dangerous glare. Polarized lenses are preferable for sports and outdoor activities because they will keep you safe and help you avoid hazards in a way that old fashioned tinted sunglasses will not. Tinted sunglasses, no matter how dark, will not protect your eyes from UV rays unless it is clearly stated on their packaging. As a matter of fact, a very dark pair of sunglasses without UV protection will harm your eyes and create strain.
