PROBLEM TO BE SOLVED: To provide a polarizing lens that is excellent in impact resistance, appearance and eye strain, and has small variation of color tone or transparency during formation..SOLUTION: A polarizing lens for a sunglass is formed by laminating a transparent protective sheet via an adhesive layer to both surfaces of a polarizing film obtained by stretching and dyeing a polyvinyl alcohol-based resin film with a dichroic organic dye; and injection molding transparent resin for a lens onto a curved polarizing lens processed in a spherical surface or an aspherical surface or onto a concave surface of the curved polarizing lens. In the polarizing lens for the sunglass, the polarizing film is stained by combined dichroic organic dyes so that dichroic ratio of the polarizing film is within a range from 5 to 14.SELECTED DRAWING: None【課題】耐衝撃性、外観や眼精疲労に対して優れ、かつ、成形時の色調や透過率の変化が少ない偏光レンズを得る。【解決手段】ポリビニルアルコール系樹脂フィルムを二色性有機色素で延伸染色した偏光フィルムの両面に接着層を介して透明な保護シートを貼り合わせ、球面或いは非球面に加工した曲げ偏光レンズまたは前記の曲げ偏光レンズの凹面にレンズ用透明樹脂を射出成形したサングラス用偏光レンズにおいて、前記偏光フィルムの二色比が5~14の範囲となるように二色性有機色素を組み合わせて染色してなるものであることを特徴とするサングラス用偏光レンズである。【選択図】なし
