Urban inequality: a hypothetic risk factor for myopia

Background: Myopia is a common refractive error with an expected increase in prevalence. Inequalities access to ocular health care for sight-threatening or life-threatening diseases have been described. Urbanization risk factor both the incidence and progression of myopia; however, socioeconomic inequalities urban settings are new concept myopia incidence.Hypothesis: Considering proven impact existing general health, inequality could be myopia. infrastructure vary between countries; there currently various manifestations inequality, scholars concerned about intra-urban as public risk. significant influence on children, because develops progresses faster during childhood, effect must examined. Although putative myopia, causal relationship should investigated. However, multifactorial etiology, originating from interaction environmental genetic factors. Thus, causality investigated through randomized, controlled trial strict matching backgrounds Conclusions: Several factors proposed, studies confirmed relationships most these experimental necessary confirm possible Certainly, will substantial challenges implementation phase.
