Abstract

La présente invention se rapporte à une lentille filtrante que l'on produit en utilisant un film plastique en tant que base, et plus particulièrement à la structure et à la production d'une lentille filtrante conçue pour des lunettes de soleil à cristaux liquides. Cette lentille filtrante se compose d'une paire de films polarisants de base, d'un élément à cristaux liquides composé d'un matériau à base de cristaux liquides pris en sandwich entre la paire de films polarisants de base et des feuilles de résine synthétique soudées sur les deux surfaces de l'élément à cristaux liquides. On peut produire cette lentille filtrante en préparant un élément à cristaux liquides comportant les films polarisants de base et les feuilles de résine synthétique, en formant une couche adhésive ou auto-adhésive sur l'une des surfaces des feuilles de résine synthétique et en soudant la paire de feuilles de résine synthétique entre lesquelles est intercalé l'élément à cristaux liquides. Il est préférable que la feuille de résine synthétique se compose d'une feuille de résine méthacrylique à orientation multi-axiale. La présente invention permet en outre de produire des lunettes de soleil présentant une transmission constante de lumière. Ce procédé consiste à déterminer la tension V1 correspondant à la transmittance maximale du polariseur et la tension V2 correspondant à sa transmittance minimale, et à fixer la tension V1 comme étant la tension seuil du dispositif à cristaux liquides et la tension V2 comme étant la tension de saturation. On peut également produire des verres dioptriques en combinant un élément à cristaux liquides TN et une lentille à cristaux liquides. La lentille filtrante présentant la structure susmentionnée est légère et ne casse pas facilement sous l'effet des chocs. Elle est donc particulièrement indiquée pour des lunettes de soleil. La lentille ci-décrite permet également de protéger les yeux des rayons solaires directs et des rayons ultra-violets et prévient la cataracte.
