主旨大意题。根据文章第二段“There are different forms of color blindness. In some cases, a man may not be able to see deep red. He may think that red ,orange and yellow are all shades of green. Sometimes a person cannot tell the differences between green and blue. In rare cases an unlucky man may see everything in shade of green—a strange world indeed”(色盲有很多种类型。在某些情况下,男人可能看不到深红色。他可能认为红色、橙色和黄色都是绿色的色调。有时一个人不能区分绿色和蓝色。在极少数情况下,一个不幸的人看到的一切都是绿色的——这真是一个奇怪的世界)以及第三段“Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color”(人类的色盲是一件很奇怪的事情。在一只眼睛里有数百万个被称为“视锥细胞”的非常小的东西。这些能帮助我们在明亮的光线下看清物体,并区分不同的颜色。还有数百万的“杆状体”,但它们是用来在接近黑暗时观察的。他们给我们看形状,但没有颜色)可知,本篇文章主要在介绍色盲以及我们的眼睛如何分辨不同的颜色和形状。故选D项。
