Un réseau (100) de lentilles stratifiées comprend : un premier réseau (10) de lentilles présentant une pluralité de lentilles (11) agencées en un réseau, chaque lentille étant constituée d'une première partie corps principal (11a) de lentille et d'une première partie bord (11b) ; et un élément ouverture lamellaire (30) disposé entre le premier réseau (10) de lentilles et un second réseau (20) de lentilles. Le premier réseau (10) de lentilles et l'élément ouverture (30) sont amenés à adhérer à l'aide d'une partie adhésive (40) formée d'un adhésif qui peut être procuré dans un état fluide. L'élément ouverture (30) présente une pluralité de parties orifice (P1) formées dans des positions correspondant aux premières parties corps principal (11a, 21a) de lentille et un ou plusieurs trous d'injection (P2) pour l'adhésif formés entre au moins un groupe de parties orifice (P1) adjacentes les unes par rapport aux autres parmi la pluralité de parties orifice (P1).
