Donning a pair of sunglasses against the brightness of the sun's rays doesn't just make it easier for you to see -- it also provides crucial protection against dangerous ultraviolet (UV) rays. In addition to selecting the proper darkness of tint and the right designer frames to suit your face and style, you must also buy sunglasses that really do block 100 percent of that UV radiation. That's why you should always get your sunglasses at Primary Eyecare and Optical of Meridian.
Sunglasses can save your sight, not only on totally sunny days but also on cloudy days (when the UV radiation can reflect off of the clouds to present an even more intense threat). Ultraviolet radiation reaches the Earth in two different forms, UVA and UVB -- and both of them can present a clear and present danger to your eyes. UV radiation is associated with cataract formation and the development of macular degeneration, as well as a more immediate (and painful) problem called photokeratitis or "snow blindness." Don't forget that UV rays can also cause skin cancer in the eyelids and around the eyes.
These dangers make a good pair of sunglasses essential -- but what makes for a good pair of sunglasses? Don't make the assumption that a darker tint means better UV protection. Tints block visible light, but they have no effect on the ultraviolet band; in fact, you can do even more damage to your eyes if that darker tint isn't accompanied by appropriate UV protection, because your pupils will be more dilated. That gorgeous pair of sunglasses you found at the mall may or may not filter out 100 percent of the UV wavelengths (which extend up to 400 nanometers).
