CA 2530858

Various non-limiting embodiments disclosed herein provide methods of making alignment facilities for optical dyes connected to an optical substrate. For example, one non-limiting embodiment provides a method of making an alignment facility for an optical dye connected to at least a portion of an optical substrate, such as an ophthalmic substrate, by forming at least one at least partial coating comprising an at least partially ordered liquid crystal material on at least a portion of the substrate. Other non-limiting embodiments related to optical elements, such as but not limited to ophthalmic elements, comprising an alignment facility for an optical dye. Still other non- limiting embodiments provide alignment facilities for optical dyes comprising coatings or sheets of an at least partially ordered liquid crystal material.

Dans des modes de réalisation variés non limités, l'invention concerne des procédés permettant de produire des systèmes d'alignement de colorants optiques connectés à un substrat optique. Un mode de réalisation non limité concerne, par exemple, un procédé permettant de produire un système d'alignement de colorant optique connecté au moins à une partie d'un substrat optique, tel qu'un substrat ophtalmique, par formation d'au moins un revêtement partiel comprenant au moins un matériau cristallin liquide partiellement ordonné sur au moins une partie du substrat. D'autres modes de réalisation non limités concernent des éléments optiques, tels que des éléments ophtalmiques non limités, comprenant un système d'alignement de colorant optique. Enfin des modes de réalisations non limités prévoient des systèmes d'alignement de colorants optiques comprenant des revêtements ou des feuilles d'au moins un matériau cristallin liquide partiellement ordonné.
