Claims28
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.
