As wonderful as sunglasses are, all sunglasses are not of the same quality and it is important to take care when shopping for a pair. The most important consideration when purchasing sunglasses is to find a pair that provides full protection from ultra violet (both UVA and UVB) rays, which are generated from the sun even on cloudy days. While experts disagree about possible negative effects UVA rays may have on the eye, it is known that UVB rays can cause a number of eye conditions including permanent retinal damage, so make sure your sunglasses are rated for full UV protection.
Sunglasses come in a variety of styles and types. If fashion is your main consideration, pick a stylish frame and then have custom lenses with UV protection added to them. If sun protection is your primary concern, pick up a pair of wraparound sunglasses that will block light that would normally skip past the frames of regular sunglasses.
After you’ve found a style that you like, think about the lenses. You’ve probably seen sunglasses with different colored lenses. While on cheap plastic sunglasses color may be little more than a fashion choice, with proper lenses, the color can tell you more about the purpose of the sunglasses. Knowing the different kinds of lenses will help you make the best decision when choosing sunglasses.
