A method of producing an optical article includes applying an imbibition composition having at least one dye onto at least a portion of at least one imbibable surface (45) of a substrate (20) to form a coated substrate (10). The method further includes irradiating at least a portion of the coated substrate with heat from a heat source (80) to form a heat gradient across the coated substrate (10) to diffuse the at least one dye into the imbibable surface to form an at least partially imbibed substrate having a dye concentration gradient corresponding to the heat gradient. The method further includes removing a residual component of the imbibition composition from the at least partially imbibed substrate. The dye concentration gradient forms a gradient pattern upon exposure to actinic radiation.
