We have been stocking Lindberg frames for many years now. Why, these frames are so well made, so light and so comfortable to wear. One of the characteristics of these frames is that there are no screws or rivets to be found in the frame. The original designer Poul jorner Lindberg, an optometrist, had to bring in an architect to design the frames to achieve this feat. The frames are a design marvel with so many little design features but the big thing is how comfortable they are to wear and how they just keep looking good through the years
