    Abstract: An optical device comprising: an optical substrate provided with selective optical filtering means configured to selectively inhibit transmission, through the optical substrate of at least one selected range of wavelengths of incident light in the visible light spectrum at an inhibition rate of at least 5%, the selective optical filtering means being further configured to transmit at least 8% of incident light of the visible spectrum outside the at least one selected range of wavelengths; wherein the at least one selected range of wavelengths has a bandwidth in a range of from 1Onm to 70nm, preferably 1Onm to 60nm centered on a wavelength within a range of between 430nm and 465 nm.

    Abstract: Un método para tratar una lente oftálmica que comprende dos lados principales, en el que al menos un lado comprende una capa externa orgánica o mineral revestida con una capa protectora temporal de MgF2, caracterizado por que el método comprende una operación de tratamiento específica seleccionada de entre las siguientes operaciones: - un tratamiento químico en fase líquida de la capa protectora temporal, que conduce a la formación de MgO y/o Mg(OH) 2 en y/o sobre la capa protectora temporal, - un depósito de al menos un óxido metálico no fluorado y/o de al menos un hidróxido metálico no fluorado sobre la capa protectora temporal mediante transferencia de la misma a partir de una película electrostática o mediante evaporación en vacío de la misma directamente sobre la capa protectora temporal.

    Abstract: A method for treating an ophthalmic lens comprising two main sides, wherein at least one side comprises an organic or mineral external layer coated with a MgF2 temporary protective layer, said method comprising a specific treating step selected amongst the following steps: - a liquid phase chemical treatment of the temporary protective layer, leading to the formation of MgO and/or Mg(OH)2 on the temporary protective layer,- a deposit of at least one non fluorinated metallic oxide and/or of at least one non fluorinated metallic hydroxide on the temporary protective layer through transfer thereof from an electrostatic film or through vacuum evaporation thereof directly on the temporary protective layer,- the deposit of the MgF2 temporary protective layer on the external layer occurs through vacuum evaporation at a speed lower than or equal to 0.5 nm/s.

    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 application of a mark on the surface of an ophthalmic glass of the type with an external hydrophobic and/or oleophobic coating with a low surface energy on a substrate or a coating with a high surface energy comprises: (a) positioning a mask, with a configuration complementary to the desired mark, between the surface to be marked and an energizing discharge source able to eliminate the external coating to reveal the underlying substrate or high energy coating; and (b) depositing on the outer coating, a temporary protective coating having a surface energy higher than that of the external coating and a thickness of less than 5 nm in order to allow the discharge to act on the external coating across the temporary protective coating.
