Close your eyes for a minute and imagine what life would be like if you couldn't see. Imagine having to read
this page, not with your eyes but with your fingers. How do you feel, then?
     With medical knowledge and skills today, two-thirds of the world's 42 million blind people should not have
to suffer (受苦). Unluckily, rich countries have this knowledge, but developing countries do not.
     ORBIS is an international charitable organization (慈善组织). Its goal is to help fight blindness all over the
world. Inside a DC-8 airplane, there is a teaching hospital with television room and classroom. Doctors are
taught the latest technology of helping the blind get sight again here. ORBIS is always trying to keep a closer
relation among countries.
     ORBIS helps those developing countries by providing sight-saving training. It has taught over 35,000 doctors
and nurses. They continue to treat thousands of blind people every year. They have travelled around the earth 3
times, visited 76 countries and treated over 20,000 blind people. They need your help to continue their work and
free people from blindness.
     For just $38, you can help one person see; for $380 you can bring sight to 10 people; $1,300 helps train a
doctor new skills; and for $13,000 you can provide a training program for a group of doctors who can make
thousands of blind people see again. Your love can help them open their eyes to the world.
