Association between vision impairment and mortality: a systematic review and meta-analysis

The number of individuals with vision impairment worldwide is increasing because of an ageing population. This paper aimed to systematically identify studies describing the association between vision impairment and mortality, and to assess the association between vision impairment and all-cause mortality.The authors found that the hazard for all-cause mortality was higher in people with vision impairment compared with those that had normal vision or mild vision impairment, and the magnitude of this effect increased with more severe vision impairment. These findings have implications for promoting healthy longevity and achieving the Sustainable
Development Goals.
