Polarized sunglasses are a type of eyewear designed to reduce glare from surfaces such as water, snow, and glass. They achieve this through a special coating on the lenses that filters out horizontal light waves, which are the main cause of glare.
To understand how polarized sunglasses work, it's essential to grasp the basics of light polarization. Light waves travel in various directions, and when they reflect off flat surfaces, they tend to become horizontally polarized. Polarized lenses contain a special chemical film that blocks these horizontal waves, thereby reducing glare.
Polarization is a physical phenomenon where waves of light or other electromagnetic radiation are restricted to particular directions of vibration. Natural light is unpolarized, meaning it vibrates in multiple planes. When light reflects off a flat surface, it becomes polarized in a horizontal direction, creating glare. Polarized lenses have a vertical filter that blocks these horizontal waves, allowing only vertically oriented light to pass through. This vertical light is less intense and improves visual clarity and comfort.
