I recently got the soupcon GM sunglasses and after about 30 mins of use they start to hurt that bone on the skull behind the ear. I was wondering if anyone else has had this problem? Will the glasses stretch out a little? Do you think they could be adujsted at an eyeglass place? I called LV and they were no help at all..."well the store won't be fimilar with our frame and I'm not sure if they'll stretch" TIA
