The World Blind Union (WBU) "... is the only organization entitled to speak on behalf of blind and partially sighted persons of the world, representing 180 million blind and visually impaired persons from about 600 different organizations in 158 countries."

WBU is divided into six regions, each with a constitution of its own. Together, the regions form the World Blind Union. The WBU is a non-political, non-religious, non-governmental, and non-profit-making organization.
