Consumer Guide to Buying Sunglasses Online
It can sometimes be intimidating choosing a pair of sunglasses. In order to get the impressive selection and low prices you can usually only find on the internet, consumers sacrifice the ability to physically touch the sunglasses and try them on. Fortunately, with some basic information, it is entirely possible to find a great set of sunglasses that meet your needs.
The first thing you must ask yourself when buying sunglasses online is what their primary purpose will be. Will you be using them for sports, such as skiing or mountain biking, or will they be used more casually? If your glasses are going to be used for sports, you should give special concern to the durability the lenses. If you need a pair of fishing sunglasses, then you will obviously need polarized lenses.
The lenses of sunglasses can be made of polycarbonate, glass, or plastic. Polycarbonate lenses are the most common material found in modern lenses. They are favored by manufacturers because they are several times more durable and a fraction as heavy as glass lenses. This allows the sunglasses to be extremely comfortable and provide a good fit, yet they still are unlikely to scratch or break if they fall off. The synthetic material allow glasses manufacturers to imbue the lens with the tinting, so there is never any worry it will scratch or peel off. For all these advantages, polycarbonate lenses are usually the choice of sports enthusiasts.
Glass lenses are also very popular because they are the "traditional" lens material and offer a very scratch resistant surface. Most modern glass lenses are treated to have the highest level of break resistance possible while eliminating distortion. Modern manufacturing methods make most glass lenses very safe to wear and can last a lifetime if given proper storage and care.
Plastic lenses are far less common than glass or polycarbonate lenses, but they are still sometimes purchased by those who need the lowest price possible. Plastic is a very light material and can offer much of the same UV protection of glass and polycarbonate lenses, but it breaks and scratches much more easily. If you can afford it, always choose glass or polycarbonate lenses over plastic lenses, especially if you are going to use them for sports.
You should also consider what special features you would like to have on your sunglasses, such as polarization. Polarization is simply a method of reducing glare. Polarized sunglasses were first used by boaters who wanted to protect their eyes from glare off the water and fishermen who wanted observe schools of fish below the water. Today, many other sports enthusiasts take advantage of polarization to see better and be safer. Skiers for example use polarized sunglasses to reduce glare off of snow. This allows them to see curves and dips in the slopes more clearly, which makes their skiing experience both more fun and more safe.
You can benefit from polarization even if you do not spend a lot of time around water and snow. Many people who use their polarized lenses to drive find that their commute is easier on their eyes because they do not have to deal with glare from puddles on the road, shiny vehicle surfaces, and flat stretches of road.
Finally, to ensure your new sunglasses will look as good on you as possible, you need to make sure the frame matches the shape of your face. If your face is round, choose square frames. If you have very high cheekbones, odds are you will look best in oval frames. If you have a very strong chin and wide forehead, you will probably prefer round frames. People whose forehead is much broader than their chin often look good in frames that feature a straight top line and curved bottom line.
