The human body is born with a variety of sense organs, among which the eye may probably be the most vital and delicate. For example, people without eyesight can not perceive all the materials and beautiful landscape. They are usually limited to some simple tasks of jobs. The eyes are essential for the vast majority of people to see their achievements. However, there are many cases of blindness which are caused by different eye diseases or natural aging. Eye professionals have been paying continuous efforts to find ways to prevent blindness because they believe that half of all blindness cases are preventable.
Every one knows that the natural degenerative processes of the eyes are irreversible. And eye diseases such as age related macular degeneration, diabetes, cataracts and glaucoma are in most cases not preventable. However, taking proper care of the precious eyes is very necessary to diminish these risks. In this consideration, some sayings are meaningful, such as prevention is always better than cure and similarly eye care is superior to eye cure. Taking good care of the eyes involves a wide variety of aspects, such as healthy diet, be free of smoking, getting rid of excessive alcohol and so on. Among them, a balanced diet containing lots of beneficial substances is quite important.
Nutrition and healthy vision have long been considered to be interactive. Getting adequate eye nutrients is believed to contribute greatly to the eye health. There are a lot of minerals and vitamins contained in many foods which can help in maintaining good vision. For instance, vitamin A is widely recognized for its role of reducing the incidence of getting cataracts and night blindness. Similarly, vitamin E also reduces the risk of developing cataracts and macular degeneration. And vitamin C can help in preventing glaucoma.
