WHO’s report may lead to greater awareness and deliver better eye health for all

Of the world's 7.8 billion people, 2.2 billion have impaired vision. Of this number, about half are treatable. In effect, they are one-eyed kings who are better off than the 39 million who are completely blind. Nevertheless, they are handicapped for normal living, as we gleaned from the first world report on vision by WHO.
