Good news, klutz: these glasses swap the usual screws in their hinges for magnets, allowing you to swap the arms easily -- and making them harder to break too.
The brainchild of Japanese studio Nendo, these Magne-hinge spectacles use disk-shaped magnets in the arms to clip neatly between two similar parts on either side of the lens frame. That makes them quickly swappable, allowing you to choose from black, metallic, tortoiseshell and blue options on a day-to-day basis. Nendo explains:
"The temples release smoothly when pulled from the side, so that users can create different looks by purchasing temples in different colours and materials."
