Abstract:
A method of making an optical article having a gradient tint and a gradient polarization. The method includes contacting one or more dye compositions including at least one of a dichroic dye, a photochromic-dichroic dye, or any combination thereof, with an optical element having a continuous coating including at least one alignment zone. At least a portion of the dye composition diffuses into the coating at a predetermined concentration gradient along at least a portion of the coating.
