A writer has given advice on how to eat to keep one"s eyes in good shape.
In an article for the Examiner, Dr Ella Faktorovich explained that omega-3 and 6 fatty acids help keep oil glands around the eyes working properly, which in turn helps to prevent dry eyes.
She warned that it may be unhealthy to consume too much omega-6, found in foods such as meat, steering people instead to fish, olive oil, garlic and fresh fruit and vegetables.
Oils of evening primrose, blackcurrant seed and borage provide the right sort of omega-6 fatty acid.
While antioxidants and vitamins C and E can help to prevent cataracts from forming, Dr Faktorovich noted that once a person develops the condition, diet alone will not help and surgery will be necessary.
Lutein and zeaxanthin are other nutrients necessary for healthy eyes.
The Royal National Institute for the Blind recommends that people eat fruits such as mango and bilberries as well as leafy green vegetables for lutein.
Some sources of zeaxanthin include corn, broccoli, eggs and oranges.
