Abstract: Un verre ophtalmique comprend un substrat transparent (3) et des moyens électro-optiques (5) intégrés au substrat pour procurer une fonction optique en réponse à un stimulus électrique. Le verre ophtalmique comprend en outre au moins une cellule photovoltaïque (6) intégrée au substrat pour alimenter les moyens électro-optiques en réponse à une lumière incidente. La cellule photovoltaïque (6) peut être incorporée à un élément opaque occupant une petite partie de la surface du verre. Alternativement, la cellule photovoltaïque (6) peut être transparente et peut recouvrir au moins en partie la surface du verre.

Abstract: A polymerizable anti-scratch coating composition comprising at least one alkoxysilane and/or a hydrolyzate of it, anisotropic particles of one or more metal oxides and/or oxyhydroxides with a principal axis D1 of length 400 nm or less and, transversely to it, a minimum dimension D2 and a maximum D3 such that D3 is greater than or equal to D2, D1/D2 = 11or more and D1/D3 = 10 or more and optionally a polymerization catalyst. Independent claims are included for (1) a substrate coated by deposition and hardening of the claimed composition; (2) the particles as defined in the main and dependent claims.

Abstract: The invention concerns a method which consists in hydrolysing an initial volume Vsi of a precursor material comprising at least a polyalkoxysilane with an amount of water such that: x H2O / x Si >/= 10 wherein x H2O and x Si represent the number of moles of H2O and Si present respectively; concentrating the hydrolysate up to a volume substantially equal to the initial volume Vsi; relaxation of the hydrolyzate until demixing into an aqueous phase and an organosilicon phase; and recuperating the organosilicon phase. The invention is applicable to optics.

Abstract: The method consists in hydrolysing an initial volume Vse of a precursor material comprising at least one polyalkoxysilane with a quantity of water such that x ⁢ ⁢ H 2 ⁢ O x ⁢ ⁢ Si >= 10 , ⁢ and where x H 2 0 and x Si represent the number of moles of H 2 0 and Si present, respectively, the concentration of the hydrolysate up to a volume substantially equal to the initial volume Vsi, leaving the concentrated hydrolysate until segregation into an aqueous phase and an organo-silicon phase, and recovery of the organo-silicon phase. A product can be obtained which comprises an organo-silicon sol comprising silicon species T 1 , T 2 , and T 3 , wherein the molar fraction of species T 2 is equal or greater than 50%, comprising a condensation rate equal to or greater than 0.65, and further defined as lacking water, as determined by analyzing a sample of said organo-silicon sol by 1 H NMR and observing the absence of peak corresponding to water.

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 invention concerns a method for printing a near-field photoinduced stable structure, and an optical fibre tip therefor. The method comprises emitting light waves with appropriate polarisation on a photosensitive material layer to induce therein a topographical modification through an opening of not more than 100 nm delimited by an opaque zone, said layer being located at not more than 100 nm from the opening. The invention is applicable to ophthalmic optics.
