Abstract: The present invention relates to a process for treating an ophthalmic lens comprising two main sides the first one of which comprises a thin external organic or inorganic layer, comprising:- at least one treatment step for the second lens side through energetic and/or reactive species capable to perform a surface physical attack and/or chemical modification,- in option, at least one or more steps for depositing inorganic or organic layers carried out simultaneously or subsequently to the treatment step through said energetic and/or reactive species,characterized in that before the treatment step through energetic and/or reactive species, a deposition of a temporary protective layer is performed onto the thin external organic or inorganic layer.Application to ophthalmic optics.

Abstract: L'invention concerne un article d'optique à propriétés antistatiques et antireflet ou réfléchissantes, comprenant un substrat ayant au moins une surface principale revêtue d'un revêtement antireflet ou réfléchissant, ledit revêtement comprenant au moins une couche électriquement conductrice comprenant au moins 30% % en masse d'oxyde d'étain (SnO ) par rapport à la masse totale de la couche électriquement conductrice, le dépôt de ladite couche électriquement conductrice ayant été réalisé sous assistance ionique, et ledit substrat ayant un taux de reprise en eau supérieur ou égal à 0,6 % en masse par rapport à la masse totale dudit substrat, le taux de reprise en eau étant mesuré après séchage préalable dudit substrat puis stockage de ce substrat pendant 800 heures dans une enceinte à 50°C sous une humidité relative de 100 % et à pression atmosphérique.

Abstract: Methods for edging optical articles comprising two main faces, at least one of which being coated with an outermost layer comprising fixing the optical article to a chuck with a holding pad that adheres to both the optical article and the chuck, wherein the surface of the holding pad contacting the optical comprises an adhesive material; and edging the optical article with an edging device; wherein prior to fixing the optical article to the chuck, at least one temporary layer of an organic material is formed onto said outermost layer of the optical article, the organic material of the temporary layer comprising at least one organic compound having a fluorinated functional moiety and at least one linking functional moiety capable of establishing at least one intermolecular bond or interaction with the adhesive material of the holding pad. Optical articles obtained via these methods.

Abstract: The treatment of an ophthalmic glass, with two principal surfaces of which at least one incorporates an external organic or mineral layer coated with a temporary protective layer of MgF 2, comprises: (a) chemical treatment by a liquid of the temporary protective layer, leading to the formation of a layer of MgO on the temporary protective layer; (b) deposition of at least one metal oxide and/or at least one non-fluoride metal hydroxide on the temporary protective layer by transfer or from an electrostatic film or by evaporation under vacuum or directly on the temporary protective layer; and (c) the deposition of the temporary protective layer of MgF 2 on the external layer by evaporation under vacuum at a speed of less than or equal to 0.5 nm/second. An independent claim is included for an ophthalmic lens treated as above.

Abstract: An optical lens incorporates a temporary external protective coating, covering at least partially one surface of the lens and incorporating at least one outer layer mechanically degradable by friction and/or contact, with the exception of an outer layer of metal oxide and/or metal hydroxide directly in contact with an under-lying layer containing magnesium fluoride. The temporary external protective coating is covered with a peelable film adhering electrostatically to the outer layer. An independent claim is also included for the edge trimming of this optical lens.
