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. |
