I've worn glasses since I was seven, so I wear sunglasses that fit over my glasses. The best I've ever worn are "Fit-Overs". They give protection from all angles, and unlike the others I've tried, they are very comfortable. For me, at least, they can be worn for long periods without driving me crazy. They're probably availabe on-line. I don't know what they cost, because my son gave me a pair. The only place I've seen them for sale is in high-end optical shops, so they're probably not cheap. Glen
