Vision impairment remains a massive, yet often preventable, global health issue affecting billions of people worldwide.
Over 2.2 billion individuals are living with some form of vision impairment, highlighting the monumental scale of the problem.
Within this group, 43 million people are classified as blind, and an additional 295 million suffer from moderate-to-severe vision impairment that significantly impacts their daily lives.
A crucial barrier to reducing these numbers is the systemic lack of adequate eye care, with one billion people lacking access to basic services necessary for prevention and treatment.
The statistics also reveal a major opportunity: 40% of childhood blindness is preventable or treatable, meaning simple interventions could save millions from a lifetime of visual disability.
Furthermore, eye examinations are not just for vision correction; they can detect over 270 different systemic health conditions, underscoring their vital role in holistic health.
World Sight Day serves as an annual reminder of the collective responsibility to promote good vision, which in turn boosts education, employment, and productivity.
