Glare can be a serious issue for some people. It is not only annoying, but it can also become dangerous. Glare from the hood of cars or the road can impair some drivers’ vision and cause accidents. The use of polarized sunglasses can reduce glare reflected from flat surfaces. For years, sports enthusiasts such as boaters and skiers have known the benefits of using polarized lenses. It was not until recently that they have become widely popular among the general public.
Light reflected from flat surfaces, resulting in glare, is generally horizontally polarized. This horizontally polarized light can be blocked by vertically oriented lenses. The result of this is the elimination of glare.
Even though polarized lenses help in reducing glare, they have some drawbacks. People figured out that using polarized sunglasses makes it harder to read displays from a liquid crystal display (LCD). LCD screens are found in many places, such as automated bank machines, and dashboard monitors in some cars. It was been proven that at certain angles, images from LCD monitors can become invisible.
Most people, however, believe that the benefits of using polarized sunglasses outweigh the negative aspects of the product. Aside from the safety advantages polarized sunglasses can offer to drivers, they are also ideal for people who are constantly outdoors. Polarized sunglasses offer a great advantage to those who participate in sports and other activities. Fishermen, for example, find polarized sunglasses extremely useful in their sport. Polarized sunglasses eliminate the glare of the sun on the water. This effect could make the water look transparent, making it easier to see what is in the water.
Regardless of whether you use them for sports or driving, polarized sunglasses are an excellent choice to protect your eyes from glare.
