Claim Text:
1. A method, comprising producing a transparent optical component having a cellular structure, adapted to provide a view of an object located on a first side of the component and at a first distance from said component, for a user situated on a second side of the component opposite the first side and at a second distance from said component, the component comprising a network of walls forming a set of cells juxtaposed parallel to a surface of the component, between the first and second sides, each wall extending perpendicularly to the surface of the component to separate two adjacent cells, and each wall having a thickness, parallel to the surface of the component, of between 0.1 μm and 5 μm, said producing including: /1/ determining a set of points in the surface of the component with an irregular distribution of said points in said surface, each point being used to form a center of one of the cells; and /2/ forming a Voronoi partition of said surface of the component, forming the Voronoi partition including determining a position and an orientation of each wall parallel to the surface of the component, said Voronoi partition including polygons constructed from the centers of the cells, such that said network of walls contains at least five walls having different respective orientations parallel to the surface of the component, wherein the optical component comprises an ophthalmic lens for spectacles, or a film configured to be applied to a transparent substrate to form an ophthalmic lens for spectacles.
