I can see how they wouldn't work for everyone, but I really like mine. Maybe my regular glasses are small, but the prescription insert allows me just as much range as they do. The bridge on the sunglasses adjusts so the lenses aren't tickling my eyelashes. I wore mine on a week long tour and wouldn't have traded them for anything. I think if I had really bad eyesight, I might be annoyed, but I don't have bifocals or anything. My only complaint is that they are so darn expensive. Mine are Rudy Project.
