For over a hundred years, colored filters have helped people with less than normal color vision, to discriminate colors. Filtered light does not restore missing or abnormal pigments within the defective eye. Contrast and discrimination provided by a suitable colored filter can help discrimination of a given set of colors, but may prevent seeing other sets of colors. The use and limitations of color filters are described as aids for color deficient vision.
一百多年来，滤色镜一直在帮助色觉低于正常水平的人辨别颜色。滤过的光线并不能恢复有缺陷眼睛中缺失或异常的色素。合适的滤色镜所提供的对比度和辨别能力有助于辨别给定的一组颜色，但可能会妨碍看到其他颜色组合。本文描述了滤色镜作为色觉缺陷辅助工具的使用方法和局限性。
