Description
La présente invention est incluse dans le champ général de la médecine préventive et de la santé publique et se réfère en particulier à un dioptre configuré pour réduire les radiations qui endommagent le système visuel.The present invention is included in the general field of preventive medicine and public health and refers in particular to a diopter configured to reduce radiation that damages the visual system.
Les longueurs d'onde dans la gamme de 180 nm à 380 nm peuvent causer des photokératites et des opacités sur le cristallin. Dans la gamme de 380 nm à 550 nm du spectre visible (lumière violette et bleue), elles peuvent provoquer des lésions photochimiques de la rétine (310 nm à 550 nm pour l'oeil aphakique). Le réchauffement par absorption de la radiation visible ou infrarouge IR A (400 nm à 1200 nm) peut contribuer à la formation d'opacités sur le cristallin. De plus, des érosions peuvent se produire sur la cornée. En conséquence de la transparence des environnements oculaires, la radiation visible ou IR A (400 nm à 1400 nm) peut produire des dommages thermiques sur la rétine. Dans la gamme des radiations infrarouges IR A et B (800 nm à 3000 nm), les lésions thermiques du cristallin sont attribuées à une dégradation des protéines cristallines. Quant aux radiations infrarouges IR B et C (1400 nm à 3000 nm et 3000 nm à 10000 nm, respectivement), l'absorption se produit principalement sur la cornée et l'humeur aqueuse. Au-dessus de 1900 nm, la cornée est l'unique environnement d'absorption, raison pour laquelle les lésions thermiques se limitent généralement à cette structure. Ce type de lésion se doit, quasi exclusivement, à l'exposition à la radiation laser. Dans les brevets ES-2 247 946, ES-2 257 976, ES-2 281 301, ES-2 281 303, ES-2 289 957, ES-2 296 552, ES-2 298 089, ES-2 303 484 et ES-2 312 284, il est fait mention de la problématique des longueurs d'onde courtes dans le spectre de 380 à 500 nm, mais aucun de ces documents n'explique le dommage que causent les radiations comprises entre 180nm et 10 000 nm. Il existe donc un besoin de fournir un élément protégeant le système visuel des radiations dommageables.30 La présente invention résout le problème envisagé à l'état de la technique. Ainsi, selon un premier aspect, la présente invention se réfère à un dioptre (nommé ci-après dioptre de la présente invention) configuré pour réduire les radiations qui endommagent le système visuel, ledit dioptre étant caractérisé en ce qu'il comprend une substance à sa superficie ou à l'intérieur, ladite substance modifiant les propriétés de transmission dudit dioptre. Dans la présente invention, le terme dioptre, selon le Manuel d'Optique Géométrique (Felipe, 1998), est une superficie de réfraction, c'est-à-dire une io superficie qui sépare deux environnements à indices de réfraction distincts. En particulier, les radiations qui endommagent le système visuel sont des radiations du spectre infrarouge, ultraviolet et/ou du spectre visible, dont les longueurs d'onde sont comprises entre 180 nm et 10 000 nm. 15 Plus particulièrement, les propriétés de transmission qui sont modifiées par le dioptre de la présente invention sont la réflexion, la réfraction, l'absorption, la dispersion, la polarisation, et/ou le phénomène interférentiel. Selon un mode de réalisation, le dioptre de la présente invention a une forme 20 plan qui peut être parallèle, concave, convexe, biconcave ou biconvexe. Plus particulièrement, la substance comprise dans le dioptre de la présente invention est sélectionnée parmi des pigments, des substances métalliques, des polymères, des composés inorganiques, des composés organiques ou un mélange de ces substances. 25 Selon un autre mode de réalisation, le dioptre de la présente invention a une forme courbe. Plus particulièrement, le dioptre de la présente invention est une lentille ophtalmique. Plus particulièrement, le dioptre de la présente invention est une lentille de contact.Wavelengths in the range of 180 nm to 380 nm can cause photokeratitis and opacities on the lens. In the range of 380 nm to 550 nm of the visible spectrum (violet and blue light), they can cause photochemical lesions of the retina (310 nm to 550 nm for the aphakic eye). The heating by absorption of visible or infrared IR A (400 nm to 1200 nm) can contribute to the formation of opacities on the lens. In addition, erosions can occur on the cornea. As a result of the transparency of the ocular environments, visible radiation or IR A (400 nm to 1400 nm) can produce thermal damage to the retina. In the range of infrared radiation IR A and B (800 nm to 3000 nm), the thermal lesions of the crystalline lens are attributed to a degradation of crystalline proteins. For infrared IR B and C radiation (1400 nm at 3000 nm and 3000 nm at 10000 nm, respectively), absorption occurs mainly on the cornea and the aqueous humor. Above 1900 nm, the cornea is the only absorption environment, which is why thermal lesions are usually limited to this structure. This type of lesion owes almost exclusively to exposure to laser radiation. In the patents ES-2 247 946, ES-2 257 976, ES-2 281 301, ES-2 281 303, ES-2 289 957, ES-2 296 552, ES-2 298 089, ES-2 303 484 and ES-2,312,284, mention is made of the problem of short wavelengths in the 380 to 500 nm spectrum, but none of these documents explains the damage caused by radiation between 180 nm and 10,000 nm. . There is therefore a need to provide an element that protects the visual system from damaging radiation. The present invention solves the problem envisioned in the state of the art. Thus, according to a first aspect, the present invention refers to a diopter (hereinafter referred to as the diopter of the present invention) configured to reduce radiations which damage the visual system, said diopter being characterized in that it comprises a substance having its surface or inside, said substance modifying the transmission properties of said diopter. In the present invention, the term diopter, according to the Geometric Optical Manual (Felipe, 1998), is a refractive area, i.e., an area that separates two environments with distinct refractive indices. In particular, radiations which damage the visual system are radiations of the infrared, ultraviolet and / or visible spectrum, whose wavelengths are between 180 nm and 10 000 nm. More particularly, the transmission properties that are modified by the diopter of the present invention are reflection, refraction, absorption, dispersion, polarization, and / or interference. According to one embodiment, the diopter of the present invention has a planar shape which may be parallel, concave, convex, biconcave or biconvex. More particularly, the substance included in the diopter of the present invention is selected from pigments, metallic substances, polymers, inorganic compounds, organic compounds or a mixture of these substances. According to another embodiment, the diopter of the present invention has a curved shape. More particularly, the diopter of the present invention is an ophthalmic lens. More particularly, the diopter of the present invention is a contact lens.
Selon un autre mode de réalisation, le dioptre de la présente invention a une forme plane. Plus particulièrement, le dioptre de la présente invention est un filtre.According to another embodiment, the diopter of the present invention has a planar shape. More particularly, the diopter of the present invention is a filter.
Selon un deuxième aspect, la présente invention se réfère à un élément qui comprend le dioptre de la présente invention, notamment des lunettes, des superficies de cadres de fenêtres, des portes ou des systèmes de division d'espaces, des visières de casque, des superficies de couverture, de revêtement, ou des parasols de tout types.According to a second aspect, the present invention refers to an element that includes the diopter of the present invention, including eyeglasses, window frame surfaces, doors or space division systems, helmet visors, areas of cover, covering, or umbrellas of any type.
Exemple 1: Dioptre : lentille de contact On dissous une quantité de 10,3 mg d'une teinture conventionnelle jaune à base de 4-Phenylazophenol, le Solvent Yellow 7 (5Y7), dans 10,01 g d'une solution de monomères contenant 66% de phényléthylamine (PEA), 30,5% de phényléthylmalonamide (PEMA) et 3,3% d'acide bisdehydrodoisynolique (BDDA), avec pour résultat une concentration de 5Y7 de 0,103 wt °/0. On incorpore ensuite 52,3 mg de bi-4-ter-butylcyclohexylperoxyde dicarboné comme catalyseur de la polymérisation.Example 1 Diopter: contact lens 10.3 mg of a conventional yellow 4-phenylazophenol dye, Solvent Yellow 7 (5Y7), were dissolved in 10.01 g of a monomer solution containing 66% phenylethylamine (PEA), 30.5% phenylethylmalonamide (PEMA) and 3.3% bisdehydrodoisynolic acid (BDDA), resulting in a concentration of 5Y7 of 0.103 wt ° / 0. 52.3 mg of bi-4-tert-butylcyclohexylperoxide dicarbonate is then incorporated as a catalyst for the polymerization.
Avec une seringue, la solution est introduite dans un moule formé par deux assiettes en verre, unies en superposition par des clips métalliques, et un anneau de Téflon de 1 mm. La solution est étendue en couche de 1 mm. La polymérisation se produit en mettant le moule dans un four à 65QC durant 17 heures. La température du four est ensuite augmentée jusqu'à 100QC durant 3 heures de plus. Une fois la polymérisation finalisée, on extrait la couche du moule, on réalise les vérifications adéquates de mesure de la protection et on procède à la taille finale. Dans cet exemple, le dioptre est donc une lentille de contact qui comprend un pigment jaune comme substance modifiant ses propriétés de transmission, notamment en augmentant l'absorbance des longueurs d'onde courtes comprises entre 350 nm et 500 nm. Exemple 2 : Dioptre : lentille ophtalmique Après calcul des paramètres de la lentille, on sélectionne des moules dont les superficies internes sont en verre et parfaitement polies, formant ainsi le négatif parfait des superficies de la lentille. Le mélange à polymériser, nommé prépolymère et constitué par un monomère 1 o et un catalyseur, est maintenu à basse température pour éviter la polymérisation avant l'injection dans le moule. Le prépolymère est ensuite introduit dans le moule à température ambiante puis agité afin d'éliminer les bulles d'air. Puis, le moule avec le prépolymère est introduit dans un récipient et on réalise la polymérisation au bain-marie, en maintenant la température à 15 40QC durant 12 heures. Puis on élève la température à 97QC durant une heure. Du fait de la réduction du volume du mélange durant la polymérisation, on a réalisé, durant le processus, le remplissage du moule avec le prépolymère. Une fois le polymère solidifié et la lentille taillée et polie, elle est immergée 20 durant 5 min dans une solution de pigment jaune à 90QC, pour une diminution d'approximativement 10%de l'absorbance de la lumière violette et bleue. Exemple 3 : Dioptre : Filtre pour fenêtres d'immeubles et/ou de véhicules Dans cet exemple, le dioptre est un filtre qui comprend un pigment jaune 25 comme substance modifiant ses propriétés de transmission, notamment en augmentant l'absorbance des longueurs d'onde courtes comprises entre 350 nm et 500 nm. Ce filtre est compris dans du verre. 30 Exemple 4 : Dioptre : lentille avec superficie miroitée Pour la préparation d'une lentille avec superficie miroitée, on utilise les solutions suivantes: - une solution 1 comprenant 30 g de nitrate d'argent mélangé à 900 cm3 d'eau distillée ; - une solution 2 comprenant 20 g de potasse caustique mélangée à 900 cm3 d'eau distillée ; - une solution réductrice 3 comprenant 50 g de glucose mélangé à 1000 cm3 d'eau distillée.With a syringe, the solution is introduced into a mold formed by two glass plates, united in superposition by metal clips, and a Teflon ring of 1 mm. The solution is extended in a layer of 1 mm. Polymerization occurs by placing the mold in an oven at 65 ° C for 17 hours. The oven temperature is then increased to 100 ° C for an additional 3 hours. Once the polymerization is finalized, the layer is extracted from the mold, adequate checks are made to measure the protection and the final size is carried out. In this example, the diopter is a contact lens that comprises a yellow pigment as a substance that modifies its transmission properties, in particular by increasing the absorbance of short wavelengths between 350 nm and 500 nm. EXAMPLE 2 Diopter: Ophthalmic Lens After calculating the parameters of the lens, molds are selected whose internal surfaces are made of glass and perfectly polished, thus forming the perfect negative of the surfaces of the lens. The mixture to be polymerized, named prepolymer and consisting of a monomer and a catalyst, is maintained at a low temperature to prevent polymerization before injection into the mold. The prepolymer is then introduced into the mold at room temperature and then stirred to remove air bubbles. Then, the mold with the prepolymer is introduced into a vessel and the polymerization is carried out in a water bath, keeping the temperature at 40 ° C. for 12 hours. Then the temperature is raised to 97QC for one hour. Due to the reduction of the volume of the mixture during the polymerization, during the process, the mold was filled with the prepolymer. Once the polymer has solidified and the lens is cut and polished, it is immersed for 5 minutes in a yellow pigment solution at 90 ° C., for a decrease of approximately 10% in the absorbance of the violet and blue light. Example 3: Diopter: Filter for windows of buildings and / or vehicles In this example, the diopter is a filter which comprises a yellow pigment 25 as a substance modifying its transmission properties, in particular by increasing the absorbance of wavelengths. from 350 nm to 500 nm. This filter is included in glass. Example 4: Diopter: lens with mirror surface For the preparation of a lens with a mirror-like surface, the following solutions are used: a solution 1 comprising 30 g of silver nitrate mixed with 900 cm 3 of distilled water; a solution 2 comprising 20 g of caustic potash mixed with 900 cm 3 of distilled water; a reducing solution 3 comprising 50 g of glucose mixed with 1000 cm 3 of distilled water.
Les solutions sont conservées dans des bouteilles opaques et sans exposition à la lumière directe. La superficie à argenter est frottée avec l'acide nitrique concentré et rincées à l'eau, puis séchée avec une serviette en fil. Puis, on instille à cette superficie un mélange à parts égales de solution mixte 2 et d'alcool, puis on la sèche et on la rince à nouveau à l'eau. Ensuite, on immerge la lentille dans un récipient rempli d'eau distillée, en maintenant la superficie à argenter vers le bas.The solutions are stored in opaque bottles and without exposure to direct light. The surface to be silvered is rubbed with concentrated nitric acid and rinsed with water, then dried with a napkin. Then, an equal mixture of mixed solution 2 and alcohol is instilled at this surface, then dried and rinsed again with water. Then, the lens is immersed in a container filled with distilled water, keeping the area to be silvered down.
Par ailleurs, on prépare une solution mixte avec 5 parties de la solution 1, auxquelles on ajoute peu à peu de l'ammoniaque jusqu'à la correcte clarification. On ajoute ensuite 6 parties de la solution 2, et de nouveau de l'ammoniaque jusqu'à éclaircissement. Enfin, on ajoute une partie de la solution 1. On obtient ainsi une solution de coloration que l'on transvase dans une bouteille obscure, après filtration. La lentille est disposée avec la superficie à miroiter vers le bas dans un récipient contenant la solution mixte sur approximativement 1 cm de hauteur puis on ajoute la solution réductrice 3 en agitant doucement le récipient qui contient ladite lentille. Les proportions de solution mixte et de solution réductrice sont de 3:1 à 2:1. Une fois l'argent déposé sur la superficie à miroiter de la lentille, on retire ladite lentille de la solution, on la rince sous un filet d'eau, puis on la met à sécher sur du papier filtre disposé sur une plaque chauffante légèrement chauffée.In addition, a mixed solution is prepared with 5 parts of the solution 1, to which ammonia is gradually added until the correct clarification. 6 parts of solution 2 are then added, and again ammonia until lightening. Finally, a portion of solution 1 is added. A coloring solution is thus obtained which is transferred to a dark bottle after filtration. The lens is disposed with the area to be dangled downward into a container containing the mixed solution approximately 1 cm in height and then the reducing solution 3 is added by gently shaking the container which contains said lens. The proportions of mixed solution and reducing solution are from 3: 1 to 2: 1. Once the silver is deposited on the mirror surface of the lens, the lens is removed from the solution, rinsed under a trickle of water, and then dried on filter paper placed on a slightly heated heating plate. .
Dans cet exemple, le dioptre est donc une lentille qui comprend de l'argent comme substance modifiant ses propriétés de transmission, notamment pour lui permettre de transmettre 40% des radiations comprises entre 380 nm et 780 nm et de réfléchir 60% de la lumière incidente.In this example, the diopter is therefore a lens that comprises silver as a substance that modifies its transmission properties, in particular to enable it to transmit 40% of the radiation between 380 nm and 780 nm and to reflect 60% of the incident light. .
Exemple 5: dioptre : lunettes de soudure Dans cet exemple, le dioptre est une lentille qui comprend des pigments verts comme substance modifiant ses propriétés de transmission, notamment de la façon suivante: Données de transmission et d'absorption de la radiation incidente: - % absorption UV (180 nm - 380 nm): 99,9%; - % transmission visible (380 nm - 780 nm): 3%; - % absorption IR (780 nm - 1100 nm): 99,5%.Example 5: Diopter: Welding Glasses In this example, the diopter is a lens that comprises green pigments as a substance that modifies its transmission properties, in particular as follows: Transmission and absorption data of the incident radiation: -% UV absorption (180 nm - 380 nm): 99.9%; - Visible transmission (380 nm - 780 nm): 3%; IR absorption (780 nm - 1100 nm): 99.5%.
