According to the WHO , at least 2.2 billion people are affected by impaired vision or blindness, of which over a billion cases could have been avoided or remain untreated. Across the globe, more than a billion people are living with impaired vision because they aren't receiving the treatment they need for conditions such as short and far-sightedness, glaucoma or cataracts. Unfortunately those most affected include people living in rural areas or low-income situations.
In Burkina Faso, as in most developing countries, blindness is a major public health issue. Children, particularly those living in rural areas, are somewhat overlooked by the few projects which deal with ocular health in the country.
