Abstract
An optical article that includes an optical element and an anisotropic coating layer formed over at least a portion of the optical element. The anisotropic coating layer can include a first light-influencing zone comprising at least one first anisotropic material and a second light-influencing zone comprising at least one second anisotropic material. The at least one of the first light-influencing zone and the second light-influencing zone further include at least one dichroic material and/or at least one photochromic-dichroic material such that the first light-influencing zone and the second light-influencing zone exhibit a different color property, a different photochromic-dichroic reversible change, a different amount of polarization, or a combination thereof.
