  [Problem to be solved] A polarizing film for sunglasses having a color that can be more freely selected and that shows smaller changes in color tone and a colored polarizing sheet using the film and a colored polarizing lens using the polarizing sheet are provided. [Solution] A polarizing film that is produced by swelling a polyvinyl alcohol film with water, uniaxially stretching it, dyeing it with an organic dichroic dye, and drying it, wherein the dichroic organic dye is made by using a dichroic organic dye composition and a coloration organic dye composition, wherein the dichroic organic dye composition comprises a combination of organic dyes having a dichroic ratio of 13 or higher used in an amount to keep the degree of polarization at 90% or more, and wherein the coloration dye composition comprises a combination of dyes having extremely low dichroic ratios of 4 or less or substantially having no dichroic ratio, laminating at least one layer of a transparent plastic sheet onto at least both sides of the polarizing film, which is obtained by using an amount of coloration organic dye composition to yield the desired color, to obtain a polarizing sheet; curving the polarizing sheet so as to impart spherical or aspherical surfaces thereto to obtain a polarizing lens or curving the polarizing sheet so as to impart spherical or aspherical surfaces thereto and injecting a transparent resin to the concave surface of the curved polarizing sheet to obtain an injection polarizing lens, wherein the transparent resin is an aromatic polycarbonate, wherein the surface of the one side of the polarizing sheet is an aromatic polycarbonate and that side is curved to make the concave surface.

  [有待解决的问题］ 本发明提供了一种颜色选择更自由、色调变化更小的太阳镜用偏光膜，以及使用该偏光膜的彩色偏光片和使用该偏光片的彩色偏光镜片。 [解决方案］ 通过用水溶胀聚乙烯醇薄膜、对其进行单轴拉伸、用有机二色性染料染色并将其干燥而制成的偏光片，其中，二色性有机染料是通过使用二色性有机染料组合物和着色有机染料组合物而制成的，其中，二色性有机染料组合物包括二色性比率为 13 或更高的有机染料组合，其使用量可使偏光度保持在 90% 或更高、将至少一层透明塑料薄膜层压在通过使用一定量的着色有机染料组合物来获得所需颜色的偏光膜的至少两面上，以获得偏光片；使偏光片弯曲，使其具有球形或非球形表面，以获得偏光透镜，或使偏光片弯曲，使其具有球形或非球形表面，并向弯曲的偏光片的凹面注入透明树脂，以获得注射偏光透镜，其中透明树脂为芳香族聚碳酸酯，偏光片的一侧表面为芳香族聚碳酸酯，该侧弯曲以形成凹面。
