The Global Vision Deficit: Why Half the World Still Can’t See Clearly
Global Context: The Scale of Challenge
Refractive errors, including myopia, hyperopia, presbyopia, and astigmatism, have quietly become one of the world’s most widespread yet under-addressed public health challenges. As per the WHO, ~3.4 billion and ~2.1 billion people are estimated to be affected by issues such as myopia and presbyopia, respectively, by the end of the decade. This translates to close to ~4.7 billion people (~55% of the global population) requiring vision correction by FY2030.
