I love the glass lenses and design. I should've measured better, but did not have a millimeter measuring tool. These glasses are great if you have a oval or narrow face, but if you have a round face like mine, they look funny. They don't go all the way to the edge of my face near my temples and it looks ridiculous. I am returning them for a larger pair of Blinde sunglasses. The measurement on this pair is 5.25 mm from temple to temple.
