Abstract
A method of making an optical article having multiple light-influencing zones can include: forming an alignment coating layer having a first alignment region and a second alignment region over at least a portion of an optical element; applying at least one anisotropic material over the first alignment region and the second alignment region by an inkjet printing device; and applying at least one dichroic material and/or at least one photochromic-dichroic material over at least one of the first alignment region and the second alignment region to form a first light-influencing zone over the first alignment region and a second light-influencing zone over the second alignment region.
