The Claim
Fifty percent of global vision impairment cases are attributable to modifiable lifestyle and metabolic risk factors.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Half of all vision impairment cases worldwide are caused by lifestyle and metabolic factors that can be changed, such as diet, physical activity, and blood sugar control.
See the scientific wording
Half of global vision impairment cases are attributable to modifiable lifestyle and metabolic risk factors.
High blood sugar and high blood pressure damage tiny blood vessels in the eye and brain, causing reduced blood flow and inflammation. This kills light-sensing cells in the retina and nerve cells that process vision, leading to permanent vision loss.
What the research says
1 studyThis study found that people with multiple health problems like high blood pressure, diabetes, and obesity were more likely to develop vision problems over time. This suggests that changing these lifestyle and health factors could help prevent some vision loss.
