Abstract:
1. A method of making an optical element comprising forming an at least partial coating comprising at least one thermally reversible photochromic-dichroic compound at least partially aligned on at least a portion of a substrate wherein forming said partial coating comprises: applying at least one anisotropic material to at least a portion of the substrate; imbibing the at least one thermally reversible photochromic-dichroic compound into at least a portion of the at least one anisotropic material; at least partially ordering at least a portion of the anisotropic material; and at least partially aligning at least a portion of the at least one thermally reversible photochromic-dichroic compound with at least a portion of the at least partially ordered anisotropic material.
