I have just received and assembled the glasses consisting of the two glasses and the band incl. Nose bridges. Eyesight is ok and the whole also makes a good impression processed. Lack in my view is the interchangeable nose bridge: the interchangeability (various widths of the nose bridge) is a press-lock needed. Conical pins are inserted into the mounting slots located on the glasses until they lock. These pins protrude then on the inside of the glasses towards the nose and press painfully on the bridge of the nose. I'll cut the pins and try to take away the pain so or at least mitigate. Perhaps I have even a special nose ... Conclusion: Well thought ...
