I honor of UV Safety Month I decided to present you all with some information on sunglasses. Sunglasses, at least versions of them, have been around for centuries! Their purposes and styles varied though the years before they evolved into what we know today. Here are some points of interest on the sunglass time line that might be of some interest.
