How cat's eyes were invented

In 1934, the late Percy Shaw almost crashed while driving home from the pub on a foggy night in West Yorkshire, in England.

He was saved when his headlights were reflected in the eyes of a cat and it gave him a brilliant idea.

He invented reflective studs for the road and called them cat’s eyes.

Rachel Naylor speaks to Percy's great-niece, Glenda Shaw.
