A coordinated effort between the International Agency for the Prevention of Blindness (IAPB) and the World Health Organization, World Sight Day is an annual day of awareness to the need for healthy vision around the world, helping people have the opportunity to see their world clearly. Today, more than 253 million people globally are blind or have moderate to severe vision impairment; of those, more than 75% of cases are avoidable through proper detection and treatment. World Sight Day generates awareness and funding for programs that support this effort.
