A method for forming sunglass lenses with a predetermined optical gradient, namely a polarized gradient, transmissivity gradient or color gradient in which an ink jet printer is used to print a gradient pattern on an oriented sheet, with the ink jet printer being provided with a dye, in one embodiment a dichroic dye and in another embodiment an iodine dye. The printed oriented sheet is incorporated into a lens to provide the lens with the associated gradient.
