Claim Text:
1. A polarization optical lens for eyeglasses in which uneven coloring by polarization color has been improved, the polarization optical lens for eyeglasses being a multi-layered polarization optical lens for eyeglasses comprising: a linear polarization functional portion; a retardation functional portion; and a back-up resin portion, wherein, in the following order, the linear polarization functional portion, the retardation functional portion and the back-up resin portion are arranged starting from an objective side of the polarization optical lens for eyeglasses toward an ocular side of the polarization optical lens for eyeglasses, wherein the retardation functional portion has a retardation of 1,000 nm or more, and wherein the linear polarization functional portion and the retardation functional portion are arranged so that an absorption axis direction of the linear polarization functional portion and a delayed phase axis direction of the retardation functional portion form an angle of 45°±20° or less.
