- By 2050, nearly half of the global population will be nearsighted, with 5 billion people affected.
- High myopia, affecting 1 billion people, carries risks of permanent vision loss like retinal damage and blindness.
- Modern lifestyles, especially intense academic workloads and lack of natural light, are major drivers of the myopia epidemic.
- Urban children are 2.6 times more likely to develop myopia than rural children, highlighting environmental triggers.
- Solutions include reducing academic pressure, increasing outdoor time, limiting screen time for young children, early detection, and following the 20-20-20 rule.
- Countries like Taiwan and Singapore are implementing measures like outdoor classes and regulated homework to combat myopia.
