Optometry magazine MiVision features research recently published online finds that dietary vitamin C provides significant protection against cataracts.
Cataracts develop due to genetic or environmental factors. There is little you can do about genetic factors, but environmental factors includes lifestyle and diet.
A 10 year study of white female twins in the UK from the TwinsUK cohort looked at dietary habits and it was found that those with higher vitamin C intake were associated with a 33% risk reduction of cataract progression and had clearer lenses after 10 years than those with lower vitamin C intake.
It seems that Vitamin C has a protective effect on cataract progression by increasing the vitamin C available in the eye fluid, which helps stop the lens from oxidising and protects it from becoming cloudy.
