285 million visually impaired people

In 2010, the number of people visually impaired was estimated to be 285 million, of whom 39 million were blind. This is a reduction in the number of people previously estimated as being visually impaired in 2004. This can be due to better data, but also due to interventions which have reduced the number of people with avoidable visual impairment.
