Safilo has launched a campaign to market its Optyl brand of plastic material to opticians. Purchase by Safilo along with the Carrera brand and its Christian Dior license many years ago, Optyl is a thermosetting plastic that is about 20 percent lighter than acetate, used in certain models of Safilo's high-end collections. The marketing campaign creates a new history for the material, making it seem as if it were created in 1970.
