Color blindness or color vision deficiency (CVD) affects around 4.5% of the population in Europe. There have been several attempts to assist color‐blind individuals using color filter glasses. Here, contact lenses are developed to assist individuals suffering from color blindness. Two dyes (Atto 488 and 565) that provide the desired absorption wavelength ranges are selected to be immobilized in soft contact lenses. The chosen dyes have absorption bands in wavelength ranges of 480–500 and 550–580 nm. Both dyes are individually immobilized in contact lenses, and over 95% of the light in the undesired ranges are blocked. The dyes do not diffuse out from lenses in artificial tears and contact lens storage solution. Performances of the developed contact lenses are compared to commercial color‐blind glasses. The contact lenses are tested in color vision deficient patients using Ishihara test. Participants indicate enhancement in the visibility of the colors and their contrast in a color rich environment. The proposed contact lenses show enhanced results as compared to commercial color‐blind glasses in indoors and achieved similar outcomes outdoors.

角膜接触镜

色盲或色盲（CVD）会影响欧洲约4.5％的人口。已经进行了多种尝试来帮助使用滤色镜的色盲个体。在这里，隐形眼镜被开发来帮助患有色盲的个体。选择提供所需吸收波长范围的两种染料（Atto 488和565）固定在软性隐形眼镜中。选择的染料在480–500和550–580 nm的波长范围内具有吸收带。两种染料都分别固定在隐形眼镜中，并且遮挡了不希望的范围内超过95％的光。染料不会在人工泪液和隐形眼镜储存液中从镜片中扩散出来。将开发的隐形眼镜与商用色盲眼镜的性能进行比较。使用Ishihara测试对色觉不足的患者进行隐形眼镜测试。与会者指出，在色彩丰富的环境中，颜色的可见性及其对比度增强了。与室内的商用色盲眼镜相比，拟议的隐形眼镜具有更好的效果，而户外则达到了类似的效果。
