The study estimates that 538 million people worldwide suffer from myopia, resulting in a significant loss of productivity worth over US$244 billion. A one-off investment of US$20 billion could eliminate avoidable vision impairment globally.
By 2050, nearly half the world's population will be short-sighted, with up to 1 billion at high risk of blindness. The rapid increase in myopia is attributed to environmental factors such as decreased time outdoors and increased near work activities.
Researchers warn that up to 1 billion people could be blind by 2050 if current interventions are not developed and implemented. Myopia is becoming increasingly prevalent worldwide, with 80-90% of school leavers in East Asia affected.
