I have been asked to work on some sunglasses designs to be used by Usain Bolt during the Olympics 2012. Well, maybe not on track but at least while warming up before the race and ideally during the ceremonies.
The lightweight frame is die-cut out of a metal sheet and then bended into its shape. A clever mechanism allows exchanging the lenses by shifting a small slider along the temples to release or to fix the grooved glasses. Fnally it remained nothing but a concept – so far.
