Necessity sparked invention for Ron Williams, an avid outdoorsman and inventor of Cablz Eyewear. Williams, who has sold medical devices for more than two decades, was in a hurry when leaving a hospital parking deck one morning. When he turned his head to check for oncoming traffic, his fabric eyewear retainer snagged, knocking his sunglasses across his face. Frustrated, Ron snatched off his sunglasses, retainer and all, and tossed them to the floorboard. They landed in a duffle bag next to a surgical steel cable used to repair complex fractures, then Ron got a bright idea.

When he got home, Ron took the cable and some electrical tape and fashioned the first Cablz prototype.
