Popis: To determine the impact of visual impairment (VI) on health-related quality of life (HRQoL) and to compare the health burden of VI in different areas in mainland China. A cohort of 6830 people from rural villages and a cohort of 3251 people from an urban city were included to receive comprehensive ophthalmologic examinations and complete the European Quality of Life-5 Dimensions 3 Levels (EQ-5D-3L) questionnaire. For urban and rural populations, a unified VI grouping standard was adopted: the eyes were classified into normal group, mild–moderate group, and severe group according to WHO standards, and then divided into 6 groups considering both eyes. We estimated the effects of VI on the EQ-5D index score using linear regression models and the association between VI and self-reported EQ-5D health problems using logistic regression models. Associations were assessed by the Spearman correlation coefficient. The prevalence of VI and the index scores of EQ-5D-3L for each subgroup of VI were higher for the rural cohort. In these two cohorts, the severity of VI in rural population (Spearman r = 0.205; p
