Abstract
A transparent optical component comprises a set of cells (15) juxtaposed on a surface of the component. Each cell encloses a determined substance so as to endow the component with particular optical characteristics, and two neighbouring cells are separated by a wall (18). Some walls are not straight at the surface of the component, so that the light diffracted by the walls does not form any luminous glint or any flashing. In particular, the walls can be curved or made up of straight segments disposed end-to-end.
