Abstract
A method for coloring an optical element in a non-uniform linear pattern is provided. The method includes (a) preparing at least one colorant composition containing at least one photochromic material; (b) depositing the colorant composition on at least one surface of the optical element in a controlled, predetermined pattern using an inkjet printing apparatus to provide a linearly gradient color pattern on the optical element when the optical element is exposed to actinic radiation; and (c) drying the colorant composition on the surface of the optical element. An optical element prepared by the method also is provided.
