Sunglasses or sun glasses (informally called shades) are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes.
Police sunglasses are not just sunglasses that are worn by law enforcement agents or Sting. They are one of the most popular styles of sunglasses. They aren't represented by Sting, but the most popular soccer (or football) player in the world, David Beckham.
As a result, the glasses are gaining quickly in popularity.Police sunglasses have a design unique to polarized sunglasses which can good compare with good quality combat boots. Many polarized sunglasses do not come in wide frames. Many Police sunglasses have wrap-around frames. Often, the worst glare comes through peripheral vision, so not having polarization on the sides of glasses can be as bad as not wearing glasses at all.
Having protection from all sides of sunglasses is important. Even if you're not facing the sun, light can bounce off a window causing a glare in your peripheral vision. In addition, light can come in from behind glasses, reflecting back into the eyes. For this reason, anti-reflective coating is common for the inside part of the lens. Sunglasses can also be tremendously useful as safety devices. By reducing glare, they allow you to be more visually aware of your surroundings. You may have noticed that most highway patrol officers wear sunglasses. Their sunglasses increase their ability to focus on objects, such as your car speeding by at 75 mph (121 kph), without having to squint.
Another issue with wider lenses is their weight. Police sunglasses are lightweight-both the polarized lenses and the frames themselves. Even a slight amount of pressure on the bridge of the nose or the temples can cause aggravation over time.
This can be very limiting if the sunglasses are being used for sports activity or driving. An intense glare can lead to sun spots for several seconds. In either sports or driving, this is not an option. This is why professional athletes use wrap-around sunglasses for complete protection. With wraparounds, anti-reflective coating may not even be necessary if the sunglasses fit closely to the face.
Sunglasses should be inconspicuous. The wearer should forget that he or she is wearing them. Poor polarization can even lead to distortion and blurring in the lenses which can also lead to eye fatigue. In addition, poorly made lenses can lead to color distortion. Police sunglasses come in gray or brown tints which are the best all-purpose tints available.
Many high-grade sunglasses have adjustable nose pads. Small adjustments can significantly add to comfort. Sunglasses which fit well can seem like an extension of the body. However, lightweight frames should not mean that the frames break easily, and this won't be a problem with Police sunglasses.
There are a lot of features to look for in sunglasses: lens tint, size of the lenses, UV protection, mirroring, anti-reflective coating, scratch-resistant coating, and basic style. Police sunglasses are some of the most fashionable sunglasses around while being high-grade enough for professional athletes. Many say they're the perfect mixture of form and function.
