Food that is good for the eyes

Food that is good for the eyes: "Which foods can help prevent eye disease and eyesight deterioration?
There are very few things we would miss as much as our eyesight. Fortunately, there are steps we can take to help our eyes remain healthier for longer.

One of these steps is to add foods to your diet that are beneficial to your eyesight in both the short and long term. Four of the most powerful eye foods are:

Berries
Berries contain natural plant chemicals called flavonoids that play an important part in the protection of the most sensitive areas of the eye.

Tuna
Tuna and other oily fish, such as salmon and mackerel, are rich in omega-3 which research has shown to protect the macula lutea - the area of the eye effected by macular degeneration. Studies have suggested that eating fish three times a week can reduce the risk of developing the age related disease by up to 50%.

Sweet Potato
Sweet potatoes are a great source of vitamin A (in the form of beta-carotene) which is essential for healthy eyes.

Carrots
Carrots contain high levels of vitamin A(one medium sized carrot provides up to ten times the RDA) which protects the eyes and enables them to function effectively."
