SUNGLASSES

Sunglasses are eyeglasses that are coated to protect your eyes from harmful sun rays and from blinding glare. The dark lenses shield and protect your eyes from the sun, and they are made in fashions ranging from normal to outrageous, to make you look cool. A good pair of sunglasses is comfortable, shields your eyes from the sun and doesn’t fall off your face when you move. Naturally they should suit you and your outfit as well, to make the picture complete. Ray Ban, Gucci and Chanel are a few popular brands of sunglasses.
     Below: I won't bore you with what 'normal' sunglasses look like, you've seen them everywhere. So here are some rather cool designs. Sunglass makers take license to create strange and beautiful works of fashion.

There are several kinds of sunglasses for different purposes. Should you want to engage in sports you'll need a pair that will stay firmly in place and enable clear vision without having to adjust your sunglasses all the time. For different kinds of sports there are appropriate sunglasses. All sports sunglasses need to be a little tougher than regular-wear sunglasses.
      And if you need eyeglasses in your every day life then prescription sunglasses are available. Even if you wear contact lenses, prescription sunglasses are worth considering.

But whatever your purpose, the main goal of sunglasses is to protect your eyes from Ultraviolet Radiation, in short UV. UV radiation can severely damage your eyes, and sunglasses were invented to protect your eyes and to enable you to walk around in the sun comfortably.

When you wear sunglasses, the darkness of the lenses allows your eyes to open up to more light, so buying cheap sunglasses without UV protection is actually dangerous... more of the sun's rays enter through your eyes. So it's important to get sunglasses with that UV protection to save your vision.
