I was looking for sports glasses that would not slip in activity from walking the dog to running, unlike regular sunglasses. These glasses fit perfectly with the right amount of pressure and have exactly the kind of nose grips I was looking for that will not catch hair if one puts the glasses on one's head. The clarity and light protection are fantastic and the curved lenses offer good protection without compromising range of sight. While I wish a brown color without mirrored lenses had been available at the time I purchased, the fit and features make these completely worth purchasing at this price!
