Sunglasses are basically a pair of semi-transparent pieces of glass, held in front of your eyes in order to protect them from bright light. Or at least that's what any conventional encyclopaedic institution would tell you. An optician would claim that the sunglasses' ability to shield your eyes from the harmful ultraviolet rays of the sun is their single most important aspect; any fashion-designer, fighter-pilot or if you are a Terminator1 would argue fiercely that looks are much more important, and, of course, the latter would be right.
The Boring Part
The sun, sends out a lot of radiation. There's the visible light which covers a certain area of the spectrum, this ranges from red to violet. Below the visible light in the spectrum there's the heat-radiation which we sometimes call infra-red radiation, microwaves and radio waves. At the other end of normal light, there's ultra-violet radiation (colours we can't see), and further up there's X-rays, gamma waves and so forth.
Ultra-violet radiation gives us a great tan, but it can damage your eyes as well as cause skin cancer. Thus it's a good idea to use sun screen and to wear sunglasses as a preventive measure.
The Stylish Part
The most important function of sunglasses is of course the style factor. The uses of a pair of sunglasses are many, too many to mention here, but wearing a pair of sunglasses can add a certain flair to any normally-clad individual.
A person whose eyes you can't see seems to be more interesting and aloof than one without sunglasses. Beware, however, since a person with sunglasses may also be very fashion-sensitive, depending on whether or not sunglasses are in fashion.
You'll appear all the more interesting for wearing a pair of sunglasses, which can't possibly be a bad thing. This depends quite heavily on which kind of sunglasses you choose. There are many kinds, for many uses:
Sunglasses are used to heighten your 'cool' or hide your face. However don't, no matter how much you need a little extra 'cool', wear sunglasses at night. It just looks silly, and desperate. Don't wear them to work either, they're definitely a leisure item. Wearing them at the office will just make people think you're either crying or trying to hide a damaged face. Wearing them also makes it harder to see what's on computer monitors. Good point.
