Overall, 75–80% of the causes of blindness and visual impairment (VI) are avoidable or treatable with early detection, evidence-based screening, and timely treatment. More specifically, for 2015, it was estimated that 81.2% of the blindness is preventable or treatable.1 Unfortunately, 90% of avoidable blindness disproportionately affects the most vulnerable communities including the poor, women, children, the elderly, and people living in rural areas.1,2
