How to prevent presbyopia?
1, sports health care law
You can often do eye exercises when you have time, which is very helpful to protect your eyes and prevent presbyopia.
The specific steps are as follows:
① Massage the eyebrows back and forth with the middle finger of both hands for 20 times;
② Massage the eyes with two hands and four fingers for 20 times;
③ Massage the bridge of the nose with the middle finger of both hands from bottom to top for 20 times;
④ Massage the temples with the middle finger of both hands clockwise for 20 times, and then counterclockwise for 20 times;
⑤ Massage the ear roots with both thumbs for 20 times;
⑥ Hold the earlobe with your thumb and forefinger and pull it down for 20 times.
2, timing overlooking method
Presbyopia is caused by severe eye fatigue. Every morning, at noon and before dusk, you should overlook 1 ~ 2 times, overlook the green plants as far as possible, and then gradually move your eyes closer from a distance, which can improve your visual function, adjust your eye muscles, relieve eye fatigue and prevent presbyopia.
3, hot compress eye protection method
When washing your face, first soak the towel in hot water, gently close your eyes, apply it to your forehead and eyes while it is hot, and exchange it several times repeatedly, so that the blood vessels in the eyes are unblocked and oxygen and nutrition are provided to the muscles in the eyes. When you have nothing to do, you can also close your eyes, put your palm on your eyes and gently cover 1 minute.
This can promote blood flow in the eyes, renew metabolism and prevent presbyopia.
4. Acupoint pressing method
After waking up every morning, close your eyes and press the middle finger of your hands on your temples, the ring finger on the fish waist point in the middle of your eyebrows, and the little finger on the bamboo point inside your eyebrows. 5 minutes each time can relieve eye muscle fatigue and make eyes bright.
5, diet regulation method
Diet regulation is very important. Presbyopia is a common eye disease in the elderly. Suffering from this eye disease is related to factors affecting lens metabolism, such as hypoxia, dehydration and lack of vitamin C, amino acids, zinc and selenium.
Older people with presbyopia should eat more vegetables, fruits, fish, meat, eggs and other foods rich in the above substances, pay attention to eating more carrots, grapes, lemons, bananas, apples, apricots, tomatoes, fisheye and so on, and avoid smoking, alcohol and spicy and greasy foods.
Etiology of presbyopia
The essence of presbyopia is the decline of eye accommodation ability, and age is the most important factor affecting accommodation ability. Adjustment, that is, the increase of the refractive power of the eye, is achieved through the shaping and convex surface of the crystal. However, the crystal keeps growing throughout its life, because the epithelial cells in the equatorial region keep forming new fibers, adding new cortex on both sides of the crystal and squeezing the old fibers into the nuclear region. Therefore, with the increase of age, the crystal density gradually increases and the elasticity gradually decreases. In addition to age, the occurrence and development of presbyopia is also related to the following factors:
1. Non-emmetropia
Hyperopia appears earlier than myopia; After wearing glasses for myopia, the distance between the corrected negative lens and the corneal apex is 12 ~ 15 mm, which reduces the adjustment requirement of the same reading distance. However, for myopia with contact lenses, presbyopia appears earlier than people wearing ordinary frame glasses because the contact lenses are worn on the corneal surface and the corrected optical system is close to the emmetropia.
Using the eye method
The adjustment demand is directly related to the working distance. Therefore, people engaged in close-range fine work are prone to presbyopia, and those engaged in close-range fine work appear presbyopia earlier than those engaged in long-distance work.
3. The physical quality of the patient
Tall people with long arms work longer distances and need less adjustment than short people with short arms, so the latter have presbyopia symptoms earlier.
4. The geographical location of the patient
Because of the influence of temperature on crystals, people living near the equator appear presbyopia symptoms earlier.
5. Effects of drugs on patients
Patients who take insulin anti-anxiety drugs, antidepressants, antipsychotics, antihistamines, spasmolytics and diuretics will have presbyopia earlier because of the effects of drugs on ciliary muscles.
What are the precautions for presbyopia diet?
1. Snacks are rich in vitamins C and E, vitamins E and C, which have a strong antioxidant effect in the body and a good protective effect on crystals. There are many such foods and fruits, such as red dates, walnuts, sesame seeds, seabuckthorn, Rosa roxburghii, persimmons, apples, oranges and lemons.
2. Presbyopia is blurred, especially at night, so you need to go to the hospital ophthalmology department for further examination and optometry, and choose the reading glasses that suit you; At the same time, it is suggested that you strengthen the diet conditioning of nourishing liver and kidney, strengthening beer and strengthening stomach, and the diet is suitable for foods rich in various nutrients and with anti-aging and anti-aging effects.
3. Provide high-quality protein food, such as mutton, beef, rabbit meat, fish, eggs, quail eggs, hard fruits, beans and bean products.
4. In the compatibility of diet and dietotherapy for presbyopia, we should pay attention to the frequent supplementation of trace elements such as copper, zinc, selenium and iodine, and at the same time pay attention to the supplementation of iron. The following foods can also be used in a targeted manner.
5. Elderly people living and living with symptoms such as hypertension, atherosclerosis, hyperlipidemia and diabetes. Therefore, presbyopia patients should not eat more foods with high animal fat content, but should eat more vegetables, such as tomatoes, cucumbers, Chinese cabbage, onions, spinach, celery, alfalfa and young garlic.
How should presbyopia maintain itself?
First, cold water eye washing method: after getting up in the morning, insist on washing your face and eyes with cold water. Soak your eyes in cold water for 1 ~ 2 minutes, and then gently rub your face and eye muscles for 20 ~ 40 times.
Second, frequent blinking method: usually use an open and closed blink to refuel and maintain eye muscles whenever you have time. At the same time, gently rub the eyelids with both hands to improve the moisturizing degree of the eyeball; Try to straighten your shoulders when you close your eyes. Close your eyes for a while and then relax. Repeat this operation.
Third, hot water application method: Wash your face with warm water of 40 ~ 50℃ before going to bed every night. When washing your face, soak the towel in hot water first and take it out. Don't wring it too dry. Apply it to forehead and eyes while it is hot, tilt your head upwards, close your eyes lightly for a while, apply it for about 1 ~ 2 minutes, and then wash your face with clear water after the temperature drops.
4. soaking method of traditional Chinese medicine: self-purchased Chinese medicine medlar and cassia seed, each12g, soaked in fresh boiling water and taken as tea frequently, can achieve the effects of nourishing liver and kidney, clearing liver and improving eyesight.
Be careful not to eat Chili and alcoholic food during taking.
The above methods should be combined and used in turn. Generally, as long as it lasts for about half a year, it will receive obvious results.
