Apparatus and method for producing a high energy marking on a surface (11) of an ophthalmic lens (10) having a low energy surface comprising a surface energizing source, such as a corona discharge source (29), which is directed at an ophthalmic lens (10) and a mask (28) corresponding to the reverse image of the desired marking applied to the lens surface so that the surface energy of the exposed area of the ophthalmic lens is increased and the resulting marking is visible by fogging.

Dispositif et procédé servant à effectuer un marquage de forte énergie sur la surface (11) d'une lentille ophtalmique (10) de faible énergie de surface, ce qui consiste à mettre en application une source d'excitation de surface, telle qu'une source de décharge Corona (29), dirigée vers la lentille ophtalmique (10), et un masque (28) correspondant à l'image inversée du marquage qu'on souhaite appliquer sur la surface de la lentille, de façon à augmenter l'énergie superficielle de la zone exposée de la lentille ophtalmique et à rendre visible le résultat par embuage.
