Abstract:
A method of making an optical article having a gradient tint and a gradient polarization. The method includes providing an optical element including a coating having at least one alignment zone. A dye composition is contacted with the coating. The dye composition includes at least one of: a dichroic dye, a photochromic-dichroic dye, or a combination thereof to diffuse at least a portion of the dye composition into the coating at a predetermined concentration gradient along at least a portion of the coating to provide the gradient tint and the gradient polarization. A kit for making an optical article having a gradient tint and a gradient polarization. An optical article prepared from a method for making an optical article having a gradient tint and a gradient polarization.
