The Claim

Higher overall cardiovascular health, as measured by a composite score of seven metrics including smoking status, BMI, blood pressure, and blood glucose, is associated with a slower rate of retinal ageing, indicated by a smaller retinal age gap, with each one-point increase in the cardiovascular health score linked to an 11% lower odds of accelerated retinal ageing in middle-aged adults.

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.

In plain English

People with better cardiovascular health, based on measures like blood pressure, BMI, and blood sugar, have retinas that appear younger than their actual age, and each improvement in their cardiovascular health score reduces the likelihood of accelerated retinal ageing.

See the scientific wording

Higher overall cardiovascular health, measured by a composite score of seven metrics including smoking, BMI, blood pressure, and blood glucose, is associated with a slower rate of retinal ageing, as indicated by a smaller retinal age gap (difference between retinal-predicted age and chronological age), with each one-point increase in the CVH score linked to a 11% lower odds of accelerated retinal ageing in a population of 26,354 middle-aged adults.

Why this might work

Poor heart and blood vessel health causes damage to the tiny blood vessels in the eye, making them narrow, stiff, or leaky. This damage changes how the blood vessels look in eye scans, and the computer model interprets these changes as the eye being older than the person's real age.

  1. Study: Association between cardiovascular health metrics and retinal ageing

    People with healthier hearts and blood vessels — like those who don’t smoke, have normal weight, and healthy blood pressure and sugar — tend to have eyes that look younger than their real age, meaning their body is ageing more slowly overall.
