Abstract
Methods are disclosed for forming polarized films and glasses having polarization efficiency that is varied in a predetermined design. In particular, such designs include monochrome and color polarization density gradients, where the non-polarized areas of films and glasses allow viewing of polarized displays without distortion. The methods include forming films and glasses that have visually uniform density while still incorporating polarization gradients. The disclosed methods also enable creation of polarization filters and glasses with increased optical density and reduced glare from multiple angles.
