Poverty and eye health, including vision disability from impairment blindness, are believed to be interrelated. The relationship between poverty health can interpreted as being two-fold, in the sense that may a cause of poor lead or deepen poverty. Evidence shows burden is high people linked each other. However empirical evidence answer questions—Does perpetuate health? How why? Does poverty?—is sparse globally; especially low middle income countries (LMICs). This article therefore aims...
