1. An electro-optic element, comprising:
a cathodic film including a cathodic component sequestered adjacent to a first electrically conductive layer by a first polymer matrix; and
an anodic film including an anodic component sequestered adjacent to a second electrically conductive layer by a second polymer matrix;
wherein at least one of the cathodic film and the anodic film is capable of reversibly attenuating transmittance of light between a transparent state and a darkened state, and
wherein the cathodic film and anodic film are configured such that a ratio of a molar amount of the cathodic component in the cathodic film to a molar amount of the anodic component in the anodic film is from greater than 1.1:1 to about 2:1.
