We cannot make Vitamin E so need to take it in our diet through food to ensure good eye health.
Vitamin E is found relatively freely in our diet, it has various actions including anti-oxidant properties.

This anti-oxidant protection is important as it then maintains the structure of the cells at the back of the eye, preventing their degeneration.
How does Vitamin E help our eyes?
Vitamin E slows the progression of AMD and cataracts.

The Age-Related Eye Disease Study (or AREDS), sponsored by the National Eye Institute, showed that a 400 IU/day of vitamin E, taken with antioxidants beta-carotene, vitamin C and zinc supplementation, slows the progression of advanced age-related macular degeneration (AMD) by about 25 percent .
Vitamin E also supports the immune system and cell membranes.
