What is Avoidable Blindness

4 out of 5--80%--of the world's blind are avoidably so.

Avoidable blindness is defined as blindness which could be either treated or prevented by known, cost-effective means. Although there are many other causes of vision impairment, IAPB seeks to address the main causes of avoidable blindness, in order to have the greatest possible impact on vision loss worldwide.
