The present invention relates to a process of edging a lens comprising forming a lens-protective transparent coating layer on the surface of the lens. When the lens coated with a transparent coating layer comprising a fluorine-containing elastomer and optionally a fluorine-containing organosilane compound and having a surface energy of less than 15 mJ/m2 is edged, the scratch of lens during handling, the damage of lens caused by chemical contaminants, and lens off-centring phenomena can be prevented. Further, such an edging process requires no adhesive tape, making the process simple, and prevents the contamination of the lens surface. Further, the inventive transparent coating layer makes it possible to measure the diopter of lens exactly owing to its transparency and it is manually removable without a chemical.

L'invention concerne un procédé de débordage d'une lentille consistant à former, à la surface de la lentille, une couche de revêtement transparente, protégeant la lentille. La couche de revêtement transparente comprend un élastomère contenant du fluor et, éventuellement, un organosilane contenant du fluor, et présente une énergie superficielle inférieure à 15 mJ/m2. Un tel procédé de débordage permet d'empêcher la rayure de la lentille durant sa manipulation, les endommagements causés par des impuretés chimiques, ainsi que des phénomènes de décentrage de la lentille. En outre, un tel procédé de débordage ne nécessite aucune bande adhésive, simplifie le processus et empêche la contamination de la surface de la lentille. De plus, la couche de revêtement transparente selon l'invention permet de mesurer la dioptrie de la lentille, du fait de sa transparence et de sa facilité d'être éliminée manuellement sans l'aide d'un produit chimique.
