In the year 2015, there was a global estimate of 253 million individuals experiencing visual impairment. Among them, 36 million were classified as blind, and an additional 217 million faced moderate to severe visual impairment (MSVI). The prevalence of those with distance visual impairment was 3.44%, with 0.49% being blind and 2.95% having MSVI. Additionally, it is estimated that 1.1 billion people were affected by functional presbyopia. The combination of a growing and aging population is poised to lead to a significant surge in the population of individuals facing blindness or moderate to severe visual impairment (MSVI). Two additional factors posing substantial risks for the future are the notable global increase in the number of people diagnosed with diabetes (which can result in diabetic retinopathy, a potentially sight-threatening condition) and those experiencing high myopia. In summary, there could be approximately 703 million people dealing with blindness or MSVI by the year 2050. A substantial investment in eye health services, especially in outpatient eye care unit, coupled with measures to shield the poorest segments of society from out-of-pocket expenses, is imperative to ensure universal access to eye health services and prevent a potential future human and societal crisis.
