Colour blindness is a condition in which a person cannot see all

colors. This defect (缺陷) is more common in men than in women. About

60 million people in China suffer from such a defect. Usually they

can see only two basic colors and live in a black and white world. They

are often unable to tell other colors, especially red from green. This

defect can bring about problems because many colour-blind people do

not realize that their eyesight is defective. They have learned

to use the colour names that everyone else uses,and they fail to know

that they do not see the colors that others see. There is a risk that

their condition may place them in danger. If they mix up red with green,

for example, they may be able to tell traffic signals only by their

brightness. Scientists believe that color blindness is a defect received

from the parents and grandparents, and no medical treatment can make

these people see as well as others.

However, the well-known eye doctor Zhao Wenging, who has invented

looking glasses to help those suffering from color blindness, said that

when some of these people tried his invention, their joy was hard to

imagine.

Somebody said it was like the window that had suddenly been thrown

open to his soul. From then on he saw such a beautiful world.

No one is very glad to hear that his body has to be cut open by

surgery (外科手术) and part of it taken out. Today, however, we need

not worry about feeling pain during the operation. The sick person

falls into a kind of sleep, and when he awakes the operation is

finished. But these happy conditions are fairly new. It is not many

years since a man who had to have operation felt all its pain.

Long ago, operatioon had usually to be done while the sick man

could feel everything. The sick man had to be held down on a table

by force while the doctors did their best for him. He could feel

all the pain if his leg or arm was being cut off, and his fearful cries

filled the room and the hearts of those who watched.

Soon after 1770, Josept Priestley discovered a gas which is now

called " Laughing gas " Laughing gas became known in America. Young

men and women went to parties to try it. Most of them spent their time

laughing, but one man at a party, Horace Wells, noticed that people did

not seem to feel pain when they were using the gas. He decided to make

an experiment on himself. He asked a friend to help him.

Wells took some of the gas, and his friend pulled out one of Well'seeth.

Wells felt no pain at all.

As he did not know enough about laughing gas , he gave a man less gas

than he should have. The man cried out with pain when his tooth was

being pulled out.

Wells tried again, but this time he gave too much of the gas , and the

man died. Wells never forgot this terrible event.
