Useful
The best kind of accessory is one that is both stylish and functional, like a messenger bag or a utility knife. Designer sunglasses definitely fall into the stylish yet functional category. They are available in a vast range of styles and are affordable enough to own several pairs, making it possible to have a pair to complement every look. But how about owning a pair for every use? Sunglasses protect the eyes from harmful UV rays, but that is not where their usefulness ends. In many sports, sunglasses are considered an important piece of athletic equipment. Depending on the sport, the style and function of the sunglasses vary. Not only do they shield the eyes from UV damage, but sunglasses also protect the eyes from sports-related injury while enhancing performance by improving visibility.
Protective
UV damage to the eyes is not reversible and can lead to problems such as cataracts, macular degeneration and eye cancer. Designer sunglasses that provide 100 per cent UV protection are the only way to protect eyes and prevent future eye diseases. Sunglasses can also greatly reduce the risk of sports-related eye injuries, such as impact or penetration to the eye and radiation of the eye. The former two injuries are fairly self-explanatory, being caused by various items coming into direct contact with the eye. Radiation of the eye is not as well publicized. This injury occurs when participating in sports that involve snow or water. The highly reflective surfaces of snow and water magnify the sun's harsh glares thus intensifying the damage that the UV rays cause, increasing the likelihood of the aforementioned eye diseases.
Improved Visibility
Enhancing athletic performance through improved visibility is anther practical attribute that sunglasses hold. The key is to select the right lens. Each of the commonly available colours function differently. Amber rose and red coloured lenses heighten contrast in partly sunny conditions, but can distort colours. Orange and yellow lenses are excellent for low light conditions because they filter blue light and provide sharper focus, making them good for both indoor and outdoor sports. Green lens tints are best in sunny conditions when it is important to maintain the colour integrity of the surrounding environment. Blue and purple coloured lenses help to reduce glare, improve colour perception and define contours. Grey tints serve to lesson overall brightness and absolutely maintain colour integrity. Grey lenses are also the best choice for improved visibility when under bright sun.
Aside from the colour of lens that is chosen, sunglasses also offer a variety of other options to choose from when looking to gain superior vision. For example, sunglasses can be purchased with different types of coatings on them to suit individual preferences. Polarized sunglasses are coated with a chemical film that neutralizes glare so that the harshness of sun and reflective surfaces is greatly reduced. Other options include mirrored, anti-reflective, water repelling and scratch resistant coatings.
Another popular style is wrap-around sunglasses. They have longer lenses that reach past the temple, protecting one's peripheral vision. Shatter-resistant lenses made from plastic or polycarbonates are a great option in cases where there is an increased chance of impact. Anti-fogging sunglasses have vents located on the side or purposely sit farther away from the face to prevent heat induced fog.
With so many options available, designer Sunglasses are the best choice for those who want to look good and see even better.
