An electro-active lens has a first substrate with a surface relief diffractive topological profile and a second substrate positioned opposite to the first substrate having a substantially smooth topological profile. A first electrode is positioned along the surface relief diffractive topological profile of the first substrate and a second electrode is positioned between the first electrode and the second substrate. The smallest distance between the electrodes is less than or equal to about 1 micron An electro-active material is positioned between the first and second electrodes and a first insulating layer is positioned between the first and second electrodes.

Une lentille électro-active comprend un premier substrat doté d'un profil topologique diffractif de relief de surface et un second substrat, positionné de façon opposée au premier substrat, doté d'un profil topologique sensiblement lisse. Une première électrode est positionnée le long du profil topologique diffractif de relief de surface du premier substrat et une seconde électrode est positionnée entre la première électrode et le second substrat. La distance la plus courte entre les électrodes est inférieure ou égale à environ 1 micron. Un matériau électro-actif est positionné entre les première et seconde électrodes et une première couche isolante est positionnée entre les première et seconde électrodes.
