Globally, it is estimated that approximately 1.3 billion people live with some form of distance or near vision impairment. People with vision impairment are more likely than those without to experience higher rates of poverty and disadvantage. Population growth and ageing will have an impact on the number of people needing eye care in the future. Globally, the majority of vision impairment is avoidable. There are effective interventions to prevent eye diseases, as well as prevent, delay or reverse vision impairment. Vision rehabilitation helps to improve functioning for people with an irreversible vision impairment.
