The present disclosure includes optical articles comprising a film layer that has first and second film surfaces and is embossed such that the first film surface defines a plurality of concave optical elements and the second film surface defines a plurality of convex optical elements. The present optical articles can include one or more optical layers coupled to the film layer. Each of the optical layer(s) can encapsulate the concave optical elements or the convex optical elements. La présente invention comprend des articles optiques comprenant une couche de film qui comporte des première et seconde surfaces de film et est gaufrée de telle sorte que la première surface de film délimite une pluralité d'éléments optiques concaves et la seconde surface de film délimite une pluralité d'éléments optiques convexes. Les présents articles optiques peuvent comprendre une ou plusieurs couches optiques couplées à la couche de film. Chacune de la ou des couches optiques peut encapsuler les éléments optiques concaves ou les éléments optiques convexes.
