What Are Polarized Sun Glasses?
For many years now people that fish or ski have been using the wonders of polarized sun glasses. Basically anyone in a glare situation will probably benefit from polarized sun glasses. When you are fishing there is the constant glare from the water and when you are skiing there is the even more potent glare from the snow. In some cases, like when you are skiing, you do not realize the damage that is being done until you get inside somewhere and your eyes have to adjust.
In some cases it can be painful and it is highly recommended that if you are going to spend a lot of time in a snow or water situation that you be sure to wear polarized sun glasses for your own protection. Too much exposure to this glare without polarized sun glasses can cause serious damage to the eyes that can be irreparable.
Have you ever been out in the sun, sometimes playing in the snow all day or something like that, and then come into the house only to be greeted by painful eyes and bright blue spots in your vision? If you do that often enough then you will damage your eyes. Your best bet is polarized sun glasses to protect your eyes. But how do polarized sun glasses work?
When the sun glares into your eyes off of water or snow it does so because of the reflection from the water or snow. For the most part this reflection is horizontally polarized. That means that the rays of light reflect in a horizontal manner when they hit your eyes. A pair of polarized sun glasses are polarized in a vertical manner to help offset these strong reflections and glares. They are highly recommended but, like everything else in the world, there are the drawbacks.
The Other Side of The Pole
Many people maintain that too many athletes and other people put their trust in polarized sun glasses and that polarized sun glasses are simply not powerful enough to really be effective against these strong sun reflections. It will be something that is debated for a very long time but for now it does not hurt to use polarized sun glasses as long as you remember the main rule of never looking directly into the sun.
Another downfall to polarized sun glasses is that sometimes they prevent you from being able to see the LCD display on your car dashboard or any other LCD display you may be looking at. It seems odd but sometimes the polarization can interfere with the LCD enough where it blocks your view. So be careful if you use your sun glasses in your car.
