Vuarnet, who won a gold medal at the 1960 Olympics, died of a stroke in Sallanches in the French Alps, the newspaper said.
He invented the aerodynamic 'egg position' used by ski racers and worked with optician Roger Pouilloux on the Skilynx lens that allowed enhanced perception of contrasts in white-out conditions, launching the Vuarnet sunglasses brand made popular by celebrities such as Miles Davis and Mick Jagger.
Vuarnet's wife Edith Bonlieu, a former French ski champion, and their son Patrick were among the members of a cult, the Order of the Solar Temple, who committed mass suicide in 1994.
