  • Patent number: 8205551
    Abstract: The inventive method consists in transferring a pattern (P) onto the optical article (1) in the form of one or several portions of transferable material (3) retained by a pressure-sensitive adhesive material layer (2) and in applying transferable material portions with the aid of a pad by placing the adhesive material layer between the pad and a pattern receiving article. The use of the pressure-sensitive adhesive material makes it possible to use the different materials in the form of a transferable material. Said method is particularly suitable for producing patterns, in particular in the form of holograms on optical lenses, in particular ophthalmic lenses.
    Type: Grant

  • Patent number: 8062444
    Abstract: The present invention relates to an apparatus for conforming a functionalized flexible planar film on an optical lens. The apparatus according to the invention may also be used in a process of functionalization of an optical lens. As a factor of the functionalization that one wishes to introduce into said optical lens and the nature of the functionalized flexible planar film used, the functionalization process is a process of gluing, transfer, or molding of a functionalized flexible planar film onto an optical lens. The implementation of each of these respective processes makes it possible to obtain a functionalized optical lens, said functionalization being adhered, transferred, or molded using a functionalized flexible planar film.

  • Patent number: 7874671
    Abstract: A pattern (P) is transferred onto an optical article (1) in the form of one or more portions of a transferable material (3, 4b) retained by a layer of latex (2). The portion or portions of transferable material are applied with a stamp after the layer of latex has been formed on the article and before the latex is dry. By using latex as the adhesive material, the nature of the transferable material may vary widely. Such a method is particularly suitable for producing patterns such as holograms on optical lenses, especially ophthalmic lenses. The layer of latex may also protect the product against shocks which may subsequently be received.

  • Patent number: 7632552
    Abstract: A multilayer polarizing structure is produced on a temporary support. The structure comprises at least one orienting layer and one polarizing layer comprising dichroic dyes, the dichroic dyes having an angular orientation determined by the orienting layer. The multilayer structure is separated from the temporary substrate before being applied onto a surface of an optical element. Applying the structure onto the optical element may be easily carried out while obtaining a quality compatible with many uses of the optical element, in particular ophthalmic uses.
