What can the elderly eat to prevent vision loss?

　　As people get older, their eyesight will inevitably deteriorate to varying degrees. This is a normal phenomenon of human aging. Therefore, many elderly people just "let nature take its course" and neither pay attention to prevention nor make timely corrections. However, relevant experts point out that although visual deterioration in the elderly is inevitable, it can be improved or delayed through dietary supplements and other means. Maintaining good vision can not only improve the quality of life in old age, but also effectively prevent Alzheimer's disease.

　　Protecting eyesight can prevent Alzheimer’s disease

　　A research team from the University of Michigan followed 1,625 American elderly people for 8.5 years and concluded that those with the highest risk of Alzheimer's disease are those with poor vision who have not received treatment. If the elderly take the initiative to seek medical treatment and wear glasses after their vision declines, the chance of suffering from Alzheimer's disease will be reduced.

　　The survey also found that elderly people with good vision are 63% less likely to develop Alzheimer's disease than elderly people with poor vision. Elderly people with poor vision who do not seek medical treatment are nine times more likely to develop Alzheimer's disease than elderly people with good vision who have regular eye examinations every year. Elderly people who have poor eyesight but have regular eye examinations and receive eye treatment every year have only a slightly, but not significantly, increased chance of developing Alzheimer's disease compared with elderly people with good vision.

　　According to the researchers, many people in the medical community have previously noticed that poor vision is related to Alzheimer's disease, and this study proves that poor vision is a phenomenon that exists before Alzheimer's disease occurs in the elderly, so it is likely to be one of the causes of Alzheimer's disease. If poor vision is not corrected, it will affect the elderly's ability to engage in activities such as walking, socializing, and exercising, which are good ways to prevent Alzheimer's disease. Although elderly Vision deterioration is normal, but it should not be ignored. Instead, you should seek medical attention immediately and wear appropriate glasses for correction.

　　The cause of sudden vision loss must be determined

　　beijing friendship Hospital Wang Yanling, chief physician of the Department of Ophthalmology, said that as age increases, the vision of many middle-aged and elderly people will decline to varying degrees. Dizziness seems to be a common phenomenon in old age. It is normal for almost all middle-aged and elderly people to feel that they cannot see clearly. However, in addition to presbyopia, cataracts, fundus diseases, glaucoma and other ophthalmic diseases disease , Systemic diseases such as diabetes, chronic nephritis, hypertension, atherosclerosis, etc. can also have adverse effects on people's vision.

　　The gradual loss of vision caused by aging is a normal physiological phenomenon, but it is a slow process. If an elderly person experiences sudden vision loss within a short period of time, it is not a good sign. It is usually caused by certain diseases. If not treated in time, it can easily lead to blindness. Therefore, all vision loss cannot be regarded as the result of normal aging. You should go to the hospital for examination and treatment in time to avoid delaying the condition.

　　Eating dark green vegetables can improve your eyesight

　　As people age, their vision gradually declines, and the main manifestations are senile vertigo and cataracts. These two eye diseases are mostly caused by the aging of the lens. Dark green vegetables such as spinach, green peppers, kale, broccoli, etc. are rich in carotenoids, which have strong antioxidant effects. They can absorb harmful light entering the eyeballs and, with their powerful antioxidant properties, prevent Eye It can prevent aging, delay vision loss, and protect the lens.

　　Whether the intake of vitamin C in the diet is sufficient can also affect the transparency of the lens, which can protect the protein and other components of the eye lens, protect the eyeball capillaries, and nourish the retina. If vitamin C is insufficient, it can easily cause the transparency of the lens to decrease, which is also one of the main causes of cataracts in the elderly. Fresh vegetables and fruits, especially dark green vegetables, are rich in vitamin C.
