Method for imparting an optical element with a light influencing property in a gradient pattern

A method for imparting an optical element with at least one light influencing property in a gradient pattern, the method comprising:

• (a) providing an optical substrate having a first surface and a second surface;
• (b) depositing a first composition over a portion of the first surface of the optical substrate so as to provide a first treated surface region and an untreated surface region, the first composition comprising a material which provides at least one light influencing property;
• (c) depositing at least one second composition over the optical substrate of (b) to provide at least a second treated surface region over at least a portion of the untreated surface region and over a portion of the first treated surface region to form a first overlap region having a width in the range of 5 to 25 millimeters;
• and
• (d) spinning the optical substrate of (c) thereby providing the optical element having a light influencing property in a non-uniform, linear pattern over the first surface thereof in one direction.
