    Abstract: The invention relates to a method of producing a substrate which is coated with a mesoporous layer and to the use thereof in ophthalmic optics. The inventive method comprises the following steps comprising: preparing a precursor sol containing (i) a precursor agent that is selected from compounds having formula M(X)4 (I), in which X is a hydrolysable group and M represents silicon or a tetravalent metal and mixtures thereof, (ii) at least one organic solvent, (iii) at least one pore-forming agent and (iv) water; depositing a film of the precursor sol on a main surface of the substrate; optionally consolidating the mesoporous structure of the deposited film; eliminating the pore-forming agent; and recovering the substrate coated with the mesoporous layer. The method is characterized in that: (i) the pore-forming agent is eliminated at a temperature of less than or equal to 150° C.; and (ii) the method comprises a step involving the introduction of at least one reactive agent bearing at least one hydrophobic group, before the deposition step and/or after said step.

    Abstract: An ophthalmic lens comprises a transparent substrate and electro-optical means integrated with the substrate to perform an optical function in response to an electrical stimulus. The ophthalmic lens further comprises at least one photovoltaic cell integrated with the substrate to power the electro-optical means in response to an incident light, and optionally also a control circuit for controlling the electrical voltage. The photovoltaic cell may be incorporated in an opaque element occupying a small fraction of the area of the lens. Alternatively, the photovoltaic cell may be transparent and may cover at least a portion of the area of the lens.

    Abstract: The present invention relates to methods of incorporating additives into a thin film formed on a substrate comprising: forming an impregnatable thin film on at least one face of a substrate; depositing an impregnation composition comprising at least one additive incorporated in an appropriate diluent medium on said impregnatable thin film by spin coating; diffusing the impregnation composition within said impregnatable thin film and; treating the substrate coated with the impregnated thin film to at least partially remove the diluent medium from the impregnated thin film. The invention also relates to the application of such methods to the production of optical lenses, including in the colouring of such lenses.

    Abstract: An optical item comprising an organic or mineral glass substrate ( 1 ) and a transparent polymeric material layer ( 3 ), characterized in that it comprises at least one intermediate layer ( 2 ) in direct contact with one main side of the substrate and the polymeric material layer, the intermediate layer(s) being made of particles of at least one colloidal mineral oxide and optionally of a binder, such (an) intermediate layer(s) having an initial porosity, and the initial porosity of the intermediate layer(s) being filled either by material from the polymeric material layer or by the substrate material if the latter is made in an organic glass and, optionally partly by the binder when present, so that the intermediate layer(s), after initial porosity filling, each represent a quarter waveplate with a wavelength in the range from 400 to 700 nm, preferably from 450 to 650 nm.

    Abstract: The invention concerns a method for incorporation comprising the following steps: (a) forming on at least one surface of a substrate a thin impregnable layer; (b) depositing by spin coating on said impregnable thin layer an impregnating composition comprising at least an additive incorporated in an appropriate diluting medium; (c) diffusing the impregnating additive within said impregnable thin layer; (d) treating the coated substrate of the impregnated thin layer to eliminate, at least partly, the diluting medium of the impregnated thin layer. The invention is useful for colouring optical lenses.

    Abstract: The inventive lens comprises an organic glass substrate having front and rear main surfaces, at least one primer coat deposited on at least one of the main surfaces of the substrate, whereby said primer coat consists of a mixture of at least biophasic particles, whereby a first phase is composed of a P1 soft-character polymer with a glass transition temperature (Tg) of less than 20 DEG C and a second phase is composed of a hard-character P2 polymer with a glass transition temperature (Tg) of more than 50 DEG C and at least one coat of an anti-abrasive covering composition deposited on the primer. The invention can be used for eye glasses.
