Getting the right sunglasses is important for protecting the health of your eyes. Most brands offer protection from UV rays from the sun. Just because your eyes are protected from these hazards, some sunglasses go a step further and use anti glare technology to make it easier to see. Many people opt for polarized lenses to get rid of problems caused by glare.
Glare is caused when light lands on a flat surface. At this point, it is reflected horizontally or is turned into polarized light. This concentrated light is often referred to as a blinding glare as it can temporarily blind anyone who sees it. When the flat surface is smooth, the glare is uniform. Surfaces that often cause bad glare are back windows on vehicles, the road, or a bumper. If the light bounced off something like ice or running water it is non-uniform. Regardless, there are sunglasses that use anti glare technology to filter this dangerous glare out.
To make crystal clear lenses polarized, a specific chemical is added to the surface during the manufacturing process. This chemical is applied in a vertical pattern. This effectively filters out the horizontal light or glare.
The most common problem with glare is that it is not a single event. It often comes in waves as the light is reflected in waves from a surface such as snow, water, or the cars around a person on the road. The good news is that when a person is wearing glasses with anti glare technology, the glare is never given the chance to get through the polarization on the lenses.
When people wear sunglasses with polarization often say that they are able to see things more clearly when they are wearing them but many have also said that objects look darker. By making items easier to see, this has the added benefit of these glasses is reduced eye strain.
Not all polarized lenses are created equal. There are things where it makes more sense to buy more expensive versions. Cheaper polarized lenses usually only have the chemical that imbues the lenses with the polarization on one side of the lens. The way it is applied makes it easier to rub off the protective coating.
When you get a more expensive pair of polarized sunglasses, the polarization chemical is applied inside the lens itself. This makes it nearly impossible to remove the protection from the glasses. The more of this chemical is used, the better and more durable the protection.
It is worth noting that the color of the lenses is not a great indication of the protection. A better way to get sunglasses with the best anti glare technology is to talk to the person selling the glasses you want. They can tell you more about how the polarization is applied to the lenses. These lenses come in just about every color so you should be able to get a color you like.
There are a number of things using sunglasses with anti glare technology can help you. They are good at lowering the amount of eye strain you experience. Some people get headaches from eye strain. Wearing polarized sunglasses can reduce the number of headaches a person experiences. By making everything appear more clear, it can be easier to enjoy the world around you. If you really like to spend time on the water or to fish, these glasses can help you see better in the water.
There are some limits to the use of polarized lenses. Because they make things look a bit darker, they are not considered to be good night vision lenses. Because of the way smartphone screens, car dashboards, and some clocks work, it can be harder to read them when wearing polarized glasses.
Sunglasses using anti glare technology were first introduced by Ray-Ban in 1936. The company wanted to help aviators fighting in World War II. The actual polarization process was developed by the Polaroid Corporation founder, Edwin H. Land. These new sunglasses were provided to aviators in the war at no charge to them.
Since 1936, a lot has changed in the world of polarized sunglasses. They are popular among people for a number of situations. They are great on a hot beach or a snowy ski slope.
