Cataract is a serious threat to the health of the elders. It refers to a disease that people couldn’t see objects in the front clearly because the lens becomes feculent. Crystal oxidative damage is said to be the initial factor of its formation. Studies have found that cataract is caused by varied reasons. As human life expectancy increases, our elderly will get a corresponding increase in the number of cataract. However, cataracts will not only affect patients’ visual acuity and quality of life, but also eventually lead to blindness in patients ( on a global scale, age-related cataract is the major cause of blindness ), which causes great burden on society. Therefore, the concern about the health of the elderly, in particular about the occurrence and development of senile cataract, is a major event of the whole society.

Today, more and more elderly are suffering from cataract, partially because of their inappropriate eyeglasses. In some cases, the old people just pick out one pair of eyeglasses casually to help themselves see objects clearly, without paying close attention to the specific requirements of glasses. Generally, the regulatory function of their eyes has partially or completely disappeared, thus, for respectively the close-and distant-vision, senile people require different strengths. If not correctly examined and adjusted, the elderly will easily suffer from cataract after a long term. Therefore, senile people must wear appropriate eyeglasses for the prevention of this serious disease.

In addition, nutritional factors are also worthy of paying attention to. A healthy and well-balanced diet would be beneficial to the eye health. In daily nutrition, senile people should note the following points to prevent cataract.

First, the elderly should eat more vitamin C, vitamin E foods. Scientists have discovered that vitamin C has a role in the prevention of cataract. It can reduce the damage of light and oxygen on crystals. Foods rich in vitamin C include tomatoes, spinach, onions, cabbage, green beans and strawberries, oranges, grapefruit, orange and so on. Meanwhile, low levels of vitamin E in blood may promote cataract. Thus, the intake of vitamin E is necessary, too.

Second, foods that are rich in selenium can help to increase visual acuity; while, the lack of selenium can induce lens opacities that will lead to cataracts. This fact has already been confirmed by scientists. Selenium-rich foods involve fish, shrimp, milk, animal liver, meat and nuts, etc.

The last but not least, having more tea is also helpful to the prevention of cataract. In a large number of observations, physicians have found out that, as for the elderly who take tea more often, their likelihood of suffering from cataract is lower. Medicine has proved that it is the tannic acid contained in the tea that helps to block the oxidation of free radicals, so tea also shows its role of effective prevention of cataract.

Anyhow, the elderly should keep a healthy diet and pay close attention to the nutrition; meanwhile, in order to effectively prevent cataract, a pair of right suitable eyeglasses is important, too. At Glassesshop.com, there are high-quality glasses that are specially designed for the elders!
