The Claim
Each incremental improvement in cardiovascular health score is associated with a progressively lower retinal age gap, indicating a dose-dependent relationship between cardiovascular health and retinal ageing.
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 better cardiovascular health scores have retinas that appear younger than their actual age, and the better their heart health, the younger their retinas appear.
See the scientific wording
The association between cardiovascular health and retinal ageing is dose-dependent, with each incremental improvement in CVH score corresponding to a progressively lower retinal age gap, suggesting a cumulative protective effect of healthy behaviors on vascular ageing.
When heart health improves, blood vessels in the eye stay more open and less damaged because the body makes more nitric oxide, which keeps blood flowing smoothly. This prevents the blood vessels from narrowing, thickening, or leaking, so the eye's structure stays younger than the person's actual age.
What the research says
1 studyStudy: Association between cardiovascular health metrics and retinal ageing
The better your heart health habits are — like not smoking, staying at a healthy weight, and keeping blood pressure low — the younger your eyes appear compared to your real age. Even small improvements in these habits are linked to slower eye ageing.
