Sunglasses do much more than make you look cool, they play an important role in protecting your eyes. Doctors advise choosing the right sunglasses to protect against ultraviolet rays, which can cause short and long term eye damage.
The single most important thing to look for when buying sunglasses is that they block 100 percent of UV rays. Also, larger frames provide more protection, especially from the sides.
Don't forget the kids -- their eyes need protection, too.
Finally, the price of the sunglasses shouldn't matter. Less expensive pairs that are marked as having 100 percent UV protection can be just as effective as more expensive options.
Over time, too much sun exposure can lead to cataracts and skin cancer around the eye.
