Abstract
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.
