Abstract
An optical system comprising an optical lens •—the optical lens comprising a substrate (2) and a self-healing coating (3) extending along at least part of a surface of the substrate, the self-healing coating having a glass-transition temperature equal to or greater than 40° C. and equal to or smaller than 60° C., and •—the optical system comprising a heating component (4) adapted to heat the self-healing coating at a temperature above the glass-transition temperature of the self-healing coating.
