We all know that if we want to keep our body in good shape we have to do physical exercise regularly as well as be careful with what we eat. What we tend to forget is that this goes for our eyes as well. Medical science confirms that a diet rich in carotenoids (类胡萝卜素) can help maintain good vision(维持好视力) and prevent against a number of eye diseases. Here's some advice about how to choose the right diet to keep your eyes healthy.
— Eat orange food. Fruits and vegetables with orange flesh are rich in carotenoids. In addition to carrots，oranges，pumpkins and sweet potatoes are also available. All of these contain high levels of carotenoids，which help to maintain good vision.
— Include dark green vegetables，such as spinach (菠菜) and broccoli (西兰花) in your diet, to act as natural sunglasses. Recent scientific studies have shown that these vegetables can help block (阻挡) the damaging UV radiation(紫外线辐射)from the sun's rays.
— Prevent some eye diseases with orange juice, yellow corn, whole milk, nuts and leafy vegetables. These foods are good sources of vitamins A, C, D and E. All of these are necessary to good eye health.
