Project ORBIS also aims at promoting peaceful cooperation among countries. ORBIS tries to help developing countries by providing training during three-week medical programs. ORBIS has taught sight-saving techniques to over 35,000 doctors and nurses, who continue to cure tens of thousands of blind people every year. ORBIS has conducted 17 plane programs is China so far. For the seven to ten million blind in China ORBIS is planning to do more for them.
