Back in 1936, a man called Edwin H. Land began experimenting with producing lenses that contained his patented Polaroid filter. It was these experiments that led to the introduction of polarized sunglasses. The concept of these sunglasses is to ensure that, when you are wearing them, the images you are seeing are maintained while the harmful UV rays are shut out. So what do these sunglasses mean for you, and who wears them?
There are a number of situations in which our vision is tainted slightly due to surface glare from aspects such as water, snow, and glass. This makes it difficult to perform a number of activities such as certain sports, driving and fishing. The polarized sunglasses that are available to us are designed to reduce glare from surfaces such as water, snow and glass; they are used as a means of helping the participant in these activities to see more clearly, allowing for the avoidance of potential hazards. For example, fishermen have long been fans of these sunglasses for the fact they allow them to see into the water that they are fishing in clearly. Normal sunglasses would simply darken everything in sight, whereas polarized sunglasses focus on and remove the glare only, leaving the wearer with better vision for whatever task they are undertaking.
Light is something that has a lot of different properties, a fact that is highlighted when it is reflected off a surface. One of these properties is known as polarization, which is what these particular sunglasses take advantage of. Basically, a normal light source produces waves; these waves then dispense in all directions. However, this is something that changes when the light source reflects off a surface such as glass, water or snow. When this happens the light does not dispense. Instead the waves polarize so they end up orientating along an axis, which is usually horizontal. This produces the glare. A normal pair of sunglasses lens would simply dim everything, which results in poor vision, whereas a polarized lens reduces the brightness of these light waves while still allowing enough optical information through to see clearly.
We all know how dangerous glare can be when the sun reflects off surfaces. Take driving, for example. We are all quick to reach for our shades, but these in some respects can often add to the problem. Everything that you could see before is darker and harder to make out. Everything that was glared is simply dimmer. With polarized sunglasses, however, everything that was hard to make out due to the glare is made sharper without affecting the surrounding objects. They select which aspect needs to be filtered and allow the light through along the non-glare axis, giving you the best vision possible.
Many people can make use of polarized sunglasses, whether you want them for driving or for playing sports. If there is any situation within your life where your vision is affected due to the reflection of light on certain surfaces, then it is recommended that you make use of them in order to correct the problem. These days this is easy enough to achieve thanks to the number of sunglasses that are available to you. So what are you waiting for? Pick your pair up of polarized sunglasses today.
