The Claim
Individuals with an ideal cardiovascular health score of 11–14 have a 42% lower odds of accelerated retinal ageing compared to individuals with a poor cardiovascular health score of 0–7, after adjusting for age, sex, ethnicity, socioeconomic status, inflammation, and history of cardiovascular disease or diabetes.
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.
People with optimal heart health markers are 42% less likely to show signs of rapid retinal ageing than those with poor heart health markers, even when accounting for age, sex, ethnicity, income, inflammation, and prior heart disease or diabetes.
See the scientific wording
Individuals with ideal cardiovascular health (CVH score 11–14) have a 42% lower odds of accelerated retinal ageing compared to those with poor CVH (score 0–7), independent of age, sex, ethnicity, socioeconomic status, inflammation, and history of cardiovascular disease or diabetes.
When blood pressure, blood sugar, body weight, and smoking status are healthy, blood vessels in the retina stay flexible and open, allowing proper blood flow. This keeps the retina's tiny blood vessels from thickening, narrowing, or becoming leaky. When these factors are unhealthy, the blood vessels lose their ability to relax, become stiff and damaged, and change shape in ways that make the retina look older than it is.
What the research says
1 studyStudy: Association between cardiovascular health metrics and retinal ageing
People with healthier hearts and blood vessels — not smoking, maintaining a healthy weight, and having normal blood pressure and sugar — were found to have eyes that looked younger than their real age, showing slower aging. Those with the healthiest habits were 42% less likely to show signs of fast eye aging.
