I love my sunglasses as much as the next girl, but I typically don't start wearing them until lunchtime when the sun is at its strongest. Or so I thought....
New research conducted in Japan found that during Spring, Summer and Fall, Ultraviolet (UV) exposure to the eye during early morning and late afternoon was approximately double that of the mid-morning/early afternoon period that is most often thought of as peak sun exposure time.
Apparently it all has to do with the angle the sun hits your eyes at those times. Think about it, mid afternoon the sun is usually overhead, whereas in the AM and PM the sun can be at eye level, especially if you are driving due east or west.
So maybe check out FabSugar to find a cute pair of sunglasses, especially now that you know you may be wearing them a whole lot more.
