1. An electro-active ophthalmic lens, comprising:
- a first substrate;
a second substrate positioned opposite to said first substrate;
a first electrode;
a second electrode positioned between said first electrode and said second substrate, wherein the largest distance between the first and second electrode is less than 10 microns;
an electro-active material including an outer perimeter that is inside an outer perimeter of the lens, and positioned between said first and second electrodes; and
a first insulating layer positioned at least one of between said first and second electrodes or surrounding said first electrode of said electro-active ophthalmic lens.

Abstract
An ophthalmic lens is presented in which the lens includes a progressive addition region and a dynamic optic. The dynamic optic and the progressive addition region are in optical communication. The progressive addition region has an add power which is less than a user'"'"'s near viewing distance add power. The dynamic optic, when activated, provides the additional needed optical power for the wearer to see clearly at a near distance. This combination leads to the unexpected result that not only does the wearer have the ability to see clearly at intermediate and near distances, but the level of unwanted astigmatism, distortion, and vision compromise are reduced significantly.
