14.About ten men in every hundred suffer from color blindness in some way.Women are luckier; only about one in two hundred is affected in this matter.Perhaps,after all,it is safer to be driven by a woman!
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 shadows of green.Sometimes a person cannot tell the difference between blue and green.In rare cases an unlucky man may see everything in shades of green------a strange world indeed.
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.
Some insects have favorite colors.Mosquitoes prefer blue to yellow.A red light will not attract insects,but a blue lamp will.In a similar way human beings also have favorite colors.Yet we are lucky.With the aid of the cones in our eyes we can see many beautiful colors by day,and with the aid of the rods we can see shapes at night.One day we may even learn more about the invisible(看不見的)colors around us.
