These sunglasses are overpriced as sunglasses, but the eyeglass case, soft liner bag and cleaning cloth are quite nice. What I notice most frequently is that the stems press against the spot above each ear to such an extent that it gives me a headache. Also, when the eyeglasses are seated correctly on my face, the frames cut off all airflow, which means that the glasses get condensation on the interior of the lenses. That closeness also means that eyelashes brush up against the lenses... not good if you're wearing mascara. (The lenses, by the way, are rather ordinary plastic but have no distortions.) Since I have a rather average-sized head and a pretty typical face shape, I imagine these sunglasses would be uncomfortable for a lot of people.
