Glasses Without Screws, Soldering or Welding

The Star Online: Ralph Anderl is the founding member and managing director of German company Ic! Berlin Brillen Gmbh, known for its patented, screwless-spring-hinge-insert system.
The company’s mainstay is sheetmetal glasses, priding itself in designing and producing them without screws, soldering or welding. The screwless system allows users to separate the temples from the front frame, and change the lenses by hand with a few twists and turns.
Sheetmetal glasses are also very flexible, said Anderl, as he firmly pulled the temples outwards to align with the main frame.
“You don’t have to worry if you accidentally sit on it or your child grabs it from your face. The structure will not be affected,” he assured. “Our problem is teaching people not to be afraid to experiment with the eyewear or use the (screwless) system.”
