[Problem to be solved] Provided is a polarizing lens that is excellent in terms of impact resistance, prevention of eye strain, and a small variation of color tone or transparency or both. [Solution] A sunglass polarizing lens that is formed by laminating a transparent protective sheet via an adhesive layer to each surface of a polarizing film that is made from polyvinyl alcohol and that is stretched and stained with dichroic organic dye; curving the resultant laminate so as to impart spherical or aspherical surfaces thereto to obtain a polarizing sheet; and injecting a transparent resin for a lens onto a surface of the polarizing sheet, wherein the polarizing film is stained by combined dichroic organic dyes so that the dichroic ratio of the film is within the range of from
