people to old age, the vision will inevitably deteriorate in varying degrees, this is the normal phenomenon of human aging, so many elderly people are "natural", neither pay attention to prevention, nor time to correct. However, experts point out that the deterioration of vision in the elderly is inevitable, but it can be improved or delayed by means of food supplement, and good eyesight can be maintained. It can not only improve the quality of life in the old age, but also effectively prevent Alzheimer's disease.
[b] protects vision to prevent Alzheimer's [/b]
the University of Michigan's research team tracked 1625 Americans for 8.5 years and concluded that the highest rates of Alzheimer's disease were poor eyesight and no one. An old man who has been treated. If the elderly take the initiative to seek medical treatment and wear glasses after falling vision, the risk of Alzheimer's disease will be reduced. The
survey also found that people with good eyesight are 63% less likely to develop Alzheimer's disease than those with poor vision, and those who have poor vision and no medical treatment are 9 times more likely to have Alzheimer's disease than those who have regular eye checks each year. Those who had poor eyesight, who had regular eye examinations every year and received eye treatment, had a slight increase in the risk of Alzheimer's disease compared to those with good vision, but it was not obvious.
according to researchers, many people in the medical community have noticed that poor eyesight is associated with Alzheimer's disease, and this study shows that poor vision is a phenomenon that exists before Alzheimer's disease occurs in the elderly, and is likely to be one of the causes of Alzheimer's disease. Poor eyesight and no correction will affect old people's activities such as walking, socializing, sports and so on, which are a good way to prevent Alzheimer's disease. Although the deterioration of vision is normal in the elderly, it can not be ignored. Instead, it should be treated immediately and wear appropriate glasses to correct it.
[b]'s sudden drop in visual acuity is a clear reason for [/b]
Wang Yanling, the director of the Department of Ophthalmology, Beijing Friendship Hospital, said that with the age of age, many middle-aged and elderly people's eyesight will decline to varying degrees. Old age seems to be a common phenomenon. Almost all the middle-aged and elderly people do not think it is normal to see things clearly. However, in addition to the eyes of old flowers, cataract, fundus disease, glaucoma and other ophthalmological diseases, systemic diseases such as diabetes, chronic nephritis, hypertension, atherosclerosis, and so on, can also cause adverse effects on people's vision. It is a normal physiological phenomenon that
aging causes the gradual decline of vision, but this is a slow process. If the old man falls short of sight, it is not a good sign. It is usually caused by some diseases. If not treated promptly, it will easily lead to blindness. Therefore, we should not take all the eyesight down as the result of normal aging. We should check the treatment in time to avoid any delay.
[b] to eat dark green vegetables can be known as [/b]
people to the elderly, the visual acuity gradually decline, the main manifestation of senile eyes and cataract, these two kinds of eye diseases are mostly caused by crystal aging. Deep green vegetables such as spinach, green pepper, Gai Lan and broccoli are rich in carotenoids. They have strong antioxidant effects and can absorb harmful light into the eyeball. With their powerful antioxidant properties, it prevents the aging of the eyes, retarded visual impairment and has the effect of protecting the lens.
the adequate intake of vitamin C in the diet can also affect the transparency of the crystal. It protects the protein and other components of the lens of the eye, protects the microvessels of the eyeball and nourishment of the retina. If vitamin C is not enough, it will lead to the decrease of lens transparency. This is also one of the main causes of senile cataract. Fresh vegetables and fruits, especially dark green vegetables, are rich in vitamin C.
