求翻译: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 nearly dark. They show us shape but no color.是什么意思?![]() ![]() Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”.
