Wang W, et al. - This research probed into the associations between the prevalence of visual impairment with socioeconomic factors at country levels. It intended to model and compute a socioeconomic-adjusted disease burden based on the yielded results. A close correlation was reported among the burden of visual impairment and socioeconomic indicators. It could assist in determining the countries requiring greater attention to such concerns. The obtained regression modeling could present an opportunity for identifying the suitable public health targets which were consistent with a country’s level of socioeconomic development.
