It was a simple trick; from a thin sheet of metal, the shape of the frames and the nosepiece were cut all at once. The nosepiece was then folded back, doing away with the need for mounted nosepieces with attached pads. What’s left, in other words, is an integrated nosepiece onto which pads can be attached directly. Theo introduced the next version of these models, in acetate. But since theo uses acetate on this one, we had to take a whole different approach. Thanks to the ingenious metal-folding system, we were able to create an open front which still holds the glass in place. The metal nosepiece has been sunken into the acetate. This means that once again, there’s no frame between the nose and the lenses.
