The Benefits of Polarized Lenses


You might be under the impression that sunglasses are a relatively modern invention, however, a lot or people are unaware of the fact that sunglasses have been around for much longer than they think. In this article, we will take a closer look at the history behind the invention of polarized lenses, as well as the kind of benefits that people can gain from wearing them.

Sunglasses with Polarized lenses have in actual fact been around for more than 7 decades, and were actually invented in the mid 1930’s by a scientist names Edwin Land. Mister Land had been conducting experiments into the polarization of lenses for a number of years before finally making the breakthrough. Thanks to his determination and persistence, we can now all enjoy spending time outdoors when the sun is at its zenith without worrying whether our eyes are getting damaged. As well as protecting our eyes from the harmful effects of the UV rays that our sun gives off, they are also great at reducing glare. Glare is the reflection of the sun’s rays on a shiny or reflective surface, such as a lake, river or pond, or even a wet road. One of the hazards that many drivers face, is the fact that after a rainstorm, if the sun makes an appearance, the wet road can act like a mirror, blinding the driver.

Testing for Polarization

You may not be aware that your sunglasses have polarized lenses fitted to them, however, there is a simple and straightforward test that you can carry out in order to determine this. The best and most simple method for testing whether the lenses in your sunglasses have polarized filters is to put them on and then look for a reflection of an object in a reflective surface. It is important to note that you should avoid looking at the reflective surface head on, and instead you need to look at it at an acute angle. If your lenses do not have polarized filters in them, then there will be no noticeable difference in the intensity of the reflection of the image.
