The elderly must not learn the eye
The medical profession has witnessed a sudden drop in vision in the elderly. The cause of blindness has been found to be caused by degeneration of the intraocular lens proteins (cataracts) and macular degeneration.
Therefore, as long as you pay attention to supplementing enough anti-free radical anti-aging substances after entering middle age, you can have a pair of eyes with clear vision.
Prevention of cataract in senile cataract is the most common cause of blindness in the elderly.
According to statistics, the probability of onset from 60 to 70 years old is 77.
8%, 80% for 71-80 years old, over 90% for those over 90 years old, and the blindness rate also increases with age.
It can be seen that active cataract is the key to protecting the vision of the elderly and improving the quality of life.
The lenticular lens of a crystallographic crystal camera is a transparent, elastic tissue made of protein, through which light can pass smoothly and whose convexity is adjusted by an additional ligament, so that the light is imaged on the macula.
If the crystal protein is partially or completely aged, hardened and turbid, and the transparent state is lost, the object light cannot pass through the incident vision film to produce a clear object image called a cataract.
Prevention of senile cataract can pay attention to the following aspects: prevention of dehydration in the body in diarrhea, massive vomiting, blood loss, excessive sweating, body temperature is higher than normal, timely and timely filling the body to lose water, blood circulation is reduced, so that tissue cells decomposeA large amount of toxic waste produced by metabolism accumulates in the body, damaging crystal proteins, which lasts for a long time, and cataracts occur many times.
As soon as possible to cure the dehydration disease and timely replenish the lost body fluid, it is an irresistible alternation to prevent cataracts.
Preventing sunlight from damaging a large amount of ultraviolet light in the sun can cause and aggravate crystal protein denaturation, turbidity, and cataract.
The research data proves that the elderly who are always paying attention to the protection of the sun, the incidence of cataract and the degree of visual impairment are lower and milder than those of the same age who are not paying attention to protection.
Walking in strong sunlight or sunbathing should be protected by a visor (or parasol) and dark glasses.
Eating a pair of bright eyes is caused by free radical peroxidation damage caused by metabolism.
It can be seen that the frequent absorption of free radical scavenging substances is the best way to prevent or delay the aging of tissue cells and protect normal physiological functions.
These anti-free radical anti-aging substances are available in your daily diet.
Therefore, the following suggestions are made: Eat more natural red foods and supplement the body’s anti-free radicals vitamins C and E.
According to the test, the concentration of vitamin C in the normal crystal of the eyeball is 30 times of the concentration in the blood; after entering the menopause, the content of antioxidants such as vitamin C and glutathione in the crystal is significantly reduced, some proteins are degraded, gradually become turbid, and cataract appears.symptom.
At this time, the calcium content of the crystal crystal increases, the potassium content decreases, becomes hard, the elasticity decreases, and the contractility of the attached ligament decreases, so that the adjustable convexity of the lens changes remarkably, resulting in a rapid decline in visual ability.
Tomato, carrot, seaweed, red leeks, red sweet potato, onion, pumpkin, hawthorn, red dates, bayberry, strawberry, mulberry, persimmon, purple grape, red apple, purple rice and other red foods, vitamin C, E and other strong antioxidantsIt has a lot of content and is rich in a large amount of β-carotene. It can be decomposed into double amount of vitamin A into the body, which can effectively prevent dry eye disease, corneal ulcer, night blindness and osteoporosis which are easily affected by the elderly.
The synergistic effect of lycopene and β-carotene in red food can significantly enhance the immune activity of macrophages in the body, prevent disease and prevent cancer; a large amount of pectin can promote the excretion of harmful substances in the intestine.
In particular, tomato seeds, the surface of which is decomposed into a large amount of malic acid and citric acid during cooking, can protect vitamin C from being destroyed by heating.
Green tomatoes contain high levels of tomatine, which can cause stomach pain, vomiting, dizziness, general weakness and other symptoms of poisoning.
Therefore, do not eat a lot of tomatoes and persimmons on an empty stomach. The large amount of pectin, persimmon phenol and soluble astringent substances contained in them will chemically react with gastric acid to form stones to replace digestive functions.
Eat more fresh green vegetables, often eat animal liver, milk or goat milk.
Among these foods, vitamins A, C, E, and B1 are high in content, so that the cornea, crystals, and retina maintain good metabolism and function to prevent degradation.
Need to be reminded that the animal liver is a detoxifying organism, it should be washed repeatedly with water before cooking, soaking, in order to prevent substances that have not been decomposed into the body to harm the health.
Drink green tea regularly to resist aging.
Recent studies by American scholars have confirmed that green tea is rich in vitamins and nutrients, and is also rich in other high-efficiency anti-aging, anti-cancer and anti-cardiovascular diseases. Its comprehensive strength is 100 times that of vitamin C.25 times more vitamin E.
Black tea and oolong tea do not contain such substances, but the amount is much less.
Early treatment of cataract in elderly cataracts, the use of antioxidants to prevent their development, to protect existing vision is no longer damaged.
In addition to eating more vitamin C, E fresh vegetables, fruits, beverages, etc., can add vitamin C50-600 mg per day, vitamin E 30 mg; at the same time with white end (carratine) or glutathione solution, every eyeEye drops 2-6 times a day, 3-6 times a day, can effectively improve the metabolism of aromatic amino acids, to the development of waterproof crystal protein denaturation.
For mature cataracts, ultrasonic emulsification therapy can be used, or an ophthalmologist can surgically remove hardened crystals and implant artificial crystals to improve vision.
Prevention of macular degeneration of the retina (1) Smoking cessation: The retinal macula is located in the center of the retina after the eyeball, with a diameter of 1-3 mm, which is the core part of visual imaging.
A survey of American medical scientists found that every 14 people over the age of 75 were blinded by retinal macular degeneration.
Further analysis showed that in these blind people, the replacement was caused by smoking directly causing atrophy of macular cells.
A variety of chemicals in tobacco, causing arteriosclerosis and coronary heart disease to occur and develop, so that the supply of retinal arterial blood is reduced, the macular cells are hypoxic, malnutrition, accelerate the development of macular cell aging and lesions.
Therefore, smoking cessation is one of the prerequisites for preventing macular destruction of blindness. (2) Eat purple grapes often, and add red wine to prevent aging.
A large number of recent studies have shown that purple grapes and red wines contain a large number of strong anti-free radicals to prevent fermentation substances such as flavonoids and phenols, which is 25 times that of vitamin E and 20 times that of white wine.
These flavonoids and phenolic substances can inhibit the aggregation of platelets in the blood vessel wall, reduce hyperlipidemia, prevent atherosclerosis and coronary heart disease, thereby preventing the occurrence and development of macular degeneration.
American scholars have not found that grapes (wine) contain a substance called “resveratuol”, which has a powerful anti-paining effect on human oncogenes and prevents tissue cell cancer.
According to tests, this anti-cancer substance is the highest in grape skin.
Therefore, it is best to eat grapes without spitting.
Older people with red wine have high blood fat, atherosclerosis, coronary heart disease, anti-aging, anti-cancer, and prevent cataract and retinal macular degeneration. Although it is ideal, daily doses and methods must meet physiological requirements.
Excessive and excessive drinking will cause or aggravate the occurrence and development of hyperlipidemia, arteriosclerosis, hypertension, coronary heart disease, cataract, and retinal macular degeneration.
According to the study, the amount of red wine is consumed every day, and it is advisable to drink less. In the middle, dinner and two slow drinks, while taking in the vegetarian diet and the right amount of staple food.
Do not drink on an empty stomach, so as not to stimulate the gastric mucosa and starch, induce gastritis and acute amygitis; the main dish is vegetarian, and the diet and oil should be less, in order to prevent the liver burden and affect the function of liver cells.
In the case of high blood pressure and coronary heart disease, alcohol should be suspended and red food intake should be increased to compensate for the lack of drinking during the period of drinking.
Immediately correct eye infections In the elderly, the eye tissue is poor in disease resistance, and bacterial and viral infections are prone to occur in the hot season. If not treated in time, it will cause a sudden loss of vision.
In the early stage, it only showed a little more tears, swelling, and the object was not as clear as before, slightly itchy, and a small amount of eyelids (actually a small amount of purulent secretions) in the corner of the eye after waking up, and other symptoms that were not noticed by the patient and the family.
At this time, you can use a broad-spectrum antibiotic aqueous solution to drop eyes, every 1-2 hours, wear dark glasses, stop reading newspapers, do not watch movies, TV, and more closed eyes and other comprehensive treatment, more feasible; 24If there is no significant improvement after the hour, it indicates that the degree of infection is relatively heavy, or the drug used is not sensitive to the infected strain, and the ophthalmologist should be consulted promptly.
In the autumn season, I also often eat “clear heat and eyesight” diet, such as chrysanthemum tea, bamboo leaf soup, mulberry leaf tea, bitter gourd soup, raw bitter gourd, chrysanthemum, boiled porridge, etc., have ophthalmic tissue and systemic infection.
