色盲测试：四个组的测试： “简单数字组”， “几何图形组”， “动物图形组”， “复杂数字图形组” 它适合征召士兵先天性色觉缺陷检测，承认大学的学生和中等专业学校和招聘工人。色盲亦称「色觉辨认障碍」，是指无法正确感知部分或全部颜色间区别的缺陷。通常色盲发生的原因与遗传有关，但部分色盲则与眼，视神经或脑部损伤有关，也可由于接触特定化学物质。英国化学家约翰·道尔顿在发现自己是色盲者后，于1798年出版了第一部论述此问题的科学专着《关于色彩视觉的离奇事实》。由于道尔顿的研究，该缺陷常被称为道尔顿病，不过现时多用色盲中的一种——绿色盲以描述道尔顿的缺陷。红绿色盲人口占全球男性人口约8%，女性人口约0.5%。其中约6%人口为三色视觉(色弱)，约2%人口为二色视觉(色盲)，极少数为单色视觉(全色盲)。色盲通常被认为是一种缺陷，然而在特定情形下，色盲者相比于正常辨色力者更有优势。不少研究指出，色盲者更擅长识别特定颜色的伪装。这在进化论上可解释先天性红绿色盲在人群中惊人的高发率。 Color Blindness Test Four group of testing: "Simple Figures Of Digits Group","Geometry Group","Animal Graphics Group","Complex Figures Of Digits Group" It suits the testing of the congenital color vision defects in conscripting soldiers, admitting students to the universities and the polytechnic schools and recruiting workers . Color blindness or color vision deficiency is the decreased ability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of some eye, nerve, or brain damage, or exposure to certain chemicals. Color blindness is usually classed as a mild disability, but in certain situations, color blind individuals have an advantage over those with normal color vision. There are some studies which conclude that color blind individuals are better at penetrating certain color camouflages .
