Purpose
Today there are a variety of sunglasses intended for different purposes. You can buy sunglasses for hiking, sports or fashion. Choose one according to your requirement. For instance, if you are a sportsperson, you can opt for a lighter pair which will help you to concentrate on your game without having to worry about visibility issues.
UV Protection
One of the most important reasons people purchase sunglasses is to protect their eyes. Opt for a pair which offers ultraviolet protection. This is a crucial factor to consider when you purchase sunglasses. Sunglasses with different types of UV protection coating are available in the market today. Choose one that safeguards your eyes from the harsh glare of the sun. However, do not opt for sunglasses that have a thick UV coating as it can hamper your visibility.
Face Structure
Remember to buy sunglasses that suit your face structure. Although sunglasses are primarily used to protect your eyes, they should also be apt for your face. Depending on the shape of your face, you can opt for different types of frames. One of the factors to consider when you are buying sunglasses is to buy a glass frame that is different from the shape of your face. For instance, if you have a round face, oval or square sunglass frames will be better than round ones.
Fit
Opt for a pair of sunglasses that fit. Often people end up buying a pair solely on the basis of its look and forget that it has to be comfortable as well. Make sure the sunglasses are not tight or hurt your ears. A good pair of sunglasses should rest on the bridge of the nose comfortably and the sides should fit properly over the ears. If the glasses are not comfortable, you should change them immediately to avoid headaches and other medical problems.
Lens
Remember to pay attention to the lens used in a pair of sunglasses before you purchase them. There are a number of lenses available such as polarized, mirror coated and photochromatic. You can opt for a lens that suits the purpose. For instance, if you play water or snow sports, you can go for polarized lenses as they decrease the glare caused by the reflection off the surface of the glasses.
These are some of the factors to keep in mind when you purchase sunglasses. Decide on a budget before you go shopping and stick to it. Remember that sunglasses should protect your eyes, be stylish and comfortable.
