I absolutely love all the glasses I've bought from this wonderful company over the years!! And my opthamologist says they're the only over-the-counter glasses that are optically correct, as good as any optician can make. Of course, she tested my eyes so I knew what magnification to get for reading And when she said I now needed a little magnification for distance--ie, driving--I bought the Seattle Eyeworks 960, with the removable polarized sunglass portion. They are so cool! Love Reading Glasses To Go!!
