Everyone knows about the importance of ultraviolet protection in their sunglasses, but how many are familiar with the protection from the “blinding glare” that finds its way into our everyday lives? Unfortunately there have been a number of cases where “blinding glare” has been cited as the cause of injury related car accidents. Most drivers have experienced those few seconds of blinding sun glare. It may only last for a few short moments, but all it takes is a second to cause an accident. According to a study by the National Highway Traffic Safety Administration (NHTSA), sun glare is the culprit behind a few hundred accidents in the U.S. every year. However, other organizations such as AAA feel that this figure is underreported because sun glare is rarely the sole cause of an accident. One U.K. study attributed an estimated 3,000 accidents to sun glare yearly.
When the sun shines, it is usually scattered in all different directions. But when it hits a flat surface, the light is reflected and becomes polarized. That polarized light is what causes the blinding glare that is experienced by the driver. This phenomenon is not just experienced while driving. For instance the polarized light reflecting from the water’s surface can affect those boating or fishing. Other examples of blinding glare that you might encounter include light reflecting off of the smooth surface of snow.
There is a very big difference between polarized sunglasses and lenses that are just tinted to let less light in. While it is possible that both kinds of lenses can have a full range of UV protection, only polarized sunglasses will cut the blinding glare that is experienced in those bright light scenarios, which is not only uncomfortable but can be dangerous while operating a moving vehicle or during recreational sports.
Fortunately there is an answer. A virtually invisible filter can be built into the lenses of your sunglasses to eliminate the amount of reflecting light that enters the eye. Polarized lenses not only reduce glare, they make images appear sharper and clearer, increasing visual clarity and comfort. When paired with your appropriate prescription they can give you the best possible vision in bright lighting conditions.
