Why Should I Care About Polarized Sunglasses?
What Is Polarization and Why Is It Important for Lenses?
When you hear the word polarization, a few things might come to mind. Maybe you remember a fishing pro talking about his polarized sunglasses that help him see into the water or maybe you think of the sophisticated physics property that is defined as a property of waves that can oscillate with more than one orientation (Wikipedia). Well believe it or not, the fishing glasses and physics property are related. Using these two common uses for the word polarization as examples, we see how they fit together, and can understand how polarized lenses work.
Light waves don’t have a specific direction or form. They can travel horizontally or vertically, and that is where polarized lenses make your vision more clear. A polarized lense only lets light travel in one direction, either vertically or horizontally, and blocks out the light going in the different way, therefore allowing your eyes to focus on the light waves on one plane, the vertical or horizontal plane. So with a fisherman’s polaroid glasses for example, when light reflects off water and into water, it goes in many different directions. By having a polarized lens that accepts only one wave plane, it rids your eyes of trying to separate all of the different wave directions, letting your eyes focus on the water, beyond the surface, and into the water. Think of it this way, without polarized lenses your eyes have to do all the work of processing light waves into one orientation, but a polarized lens does all the work, making the process of focusing much easier for your eyes.
The effects of the polarization of light is that one, you can avoid unnecessary eye strain, two, UV rays are reflected off the lenses, and your eyes are protected, and lastly, colors are more vibrant and true, and details are seen more precisely. When given the opportunity to buy polarized or non-polarized glasses, polarized would be the wise choice because of all of the benefits they provide.
