New York, March 6 (TIWN) People with more severe vision impairment are at a higher risk of all-cause mortality as compared to those with normal vision or mild vision impairment, says a new study.

A meta-analysis in The Lancet Global Health, consisting of 48,000 people from 17 studies, found that those with more severe vision impairment had a higher risk of all-cause mortality compared to those that had normal vision or mild vision impairment.

According to the data, the risk of mortality was 29% higher for participants with mild vision impairment, compared to normal vision. The risk increases to 89% among those with severe vision impairment.

Importantly, four of five cases of vision impairment can be prevented or corrected. Globally, the leading causes of vision loss and blindness are both avoidable: cataract and the unmet need for glasses.
