A number of studies have found links between eye health and diet. Most of this research has focused on two conditions, age related macular degeneration and cataracts.

Evidence

There is a lot of evidence to suggest that diets rich in antioxidants will slow down the development of age-related cataract. There has also been significant research on the affect diet can have on dry eye for example, a large study in the USA found that women who consumed five servings of tuna per week were at a 68% reduced risk of suffering from dry eyes.

Reduce the symptoms

Specsavers’ clinical spokesman, Dr Nigel Best, says: ‘Omega-3s have been found to reduce the symptoms of dry eye while vitamin C supplements can help treat inflammation of the eyelids.

Visual impairment

‘The progression of age related macular degeneration, which is the most common cause of severe visual impairment in the UK, can be reduced by taking anti-oxidant vitamin supplements. A diet rich in fruit and leafy green vegetables will also help.’

Diet myth… carrots help you see in the dark 

Carrots are said to help you see in the dark because of their vitamin A content. It is however extremely unlikely that a UK resident would be so deficient in vitamin A that their eyesight was affected.
