285 million people visually impaired worldwide
In 2010, it was estimated that 285 million people worldwide suffered from visual impairment, with 246 million described as having low vision and 39 million described as being blind.
The two main causes of visual impairment worldwide are uncorrected refractive errors such as myopia and unoperated cataract.
Approximately 90% of visually impaired people live in developing countries. While 65% of all visually impaired people are aged 50 and older, an estimated 19 million children are visually impaired. Of these, 12 million have refractive errors that could be easily diagnosed and corrected.
The XOVA program aims to help reduce the burden of blindness around the world by providing funding to projects that strive to make improvements within the field of eye care.
