Vision impairment affects 2.2 billion people globally—over half preventable—causing 4.2 million years of disability yearly, disproportionately impacting low-income areas, women, and the elderly from aging and access barriers. 

Key causes like refractive errors (glasses-fixable), cataracts (surgically treatable), glaucoma, macular degeneration, and diabetic retinopathy are worsened by UV exposure, smoking, poor diet, and screening gaps. 

WHO s Vision 2030 pushes integrated primary care, universal eyewear, school screenings, and diabetes management to avert 90% of cases, but funding, training, and equity hurdles call for amplified advocacy and tech to protect productivity and independence.
