Abstract

A method for imparting an optical element with at least one light influencing property in a gradient pattern. The method includes (a) providing an optical substrate having first and second surfaces; (b) depositing a first composition over the first surface of the optical substrate so as to provide a first treated surface region and an untreated surface region, the first composition including a material which provides a light influencing property; (c) depositing a second composition over the optical substrate of (b) to provide a second treated surface region over the untreated surface region and over a portion of the first treated surface region to form a first overlap region; and (d) spinning the optical substrate of (c) thereby providing the optical element having a light influencing property in a gradient pattern.
