只有色盲才懂得的3件事

    Most people dismiss colorblind people as having a minor problem with red and green. As we shall see bel ow, color vision deficiency is not as simple as that! Here are 3 things that the colorblind will understand only too well. It is much more than an eye health problem.
　　大多数人都认为色盲只是对红色和绿色有问题。正如下文所提到的那样，对色彩的辨识缺陷并不只是那样简单。这里列举了只有色盲知道的3件事。那不只是眼睛的健康问题。
　　1. People think their world is only in black and white.
　　人们认为他们的世界里只有黑色和白色
　　When people see the world in black and white, this is not the usual color blindness at all. It is a condition known as achromatopsia and sufferers see the world in different shades of grey. It is rather like viewing the world on an old black and white TV. Fortunately, this condition is very rare .
　　当人们看到的世界只有黑色和白色的时候，那不是一般的色盲。那是完全色盲的一个条件，忍受着看世界就是不同程度的灰色阴影。看整个世界就像是在看一个老式的黑白电视。幸运的是，这种情况非常少见。
　　2. People think the colorblind mix up red and green.
　　人们认为色盲就是分不清红色和绿色
　　It would be great if it were that simple. They think that they just get their reds and greens confused. But, if you look at the actual cause of color blindness, it tells a different story. The eye has certain nerve cells, called cones, in the retina which can differentiate color. When this is defective, the eye fails to pick up the red elements so the colors of red and green appear to be the same color.
　　如果真那么简单就好了。他们认为他们只是分不清红色和绿色。但是如果你看真实生活中的色盲会发现是完全不一样的。眼睛里面有某种神经细胞，叫做视锥细胞，是存在于视网膜上的区分颜色的细胞。当这种细胞出现问题的时候，眼睛就不能分清红色，所以红色和绿色就成了一样的颜色。
　　3. People think it is a minor problem.
　　人们认为那只是小问题
　　Many people dismiss color blindness as a minor disability. But the reality of life tells a different story. They may have problems when gardening or when they have to prepare food, not to mention when buying clothes. Laying the table may become problematic when they select the ketchup instead of the chocolate sauce for the dessert.
　　许多人认为色盲是一种很细小的缺陷。但是现实却不是这样。他们在种植的时候、在准备食物的时候可能会遇到问题，就更别提买衣服的时候了。当他们在选用番茄酱而非巧克力酱做小吃布置餐桌的时候也可能会有问题。
