In the last year and a half, my eyes have been feeling bloated, especially after exercise, fatigue and tension, swollen eyes, dryness and discomfort?

Sitting in front of a computer for a long time or in a heated environment, people often feel dry eyes and blurred vision, which are all symptoms of dry eye.

German medical scientists have recently warned that people should pay attention to this disease, otherwise long-term illness will easily cause damage to the eyes and even blindness. Medical experts from the German Ophthalmology Association said that burning eyes, or red eyes and foreign body sensation are all symptoms of dry eye. Conscious tears can alleviate this symptom, but not cure it.

There are many reasons for this disease, such as long-term use of computers, smoking and dirty air. Especially in winter, long-term exposure to heating environment is more likely to cause this disease. According to statistics, in recent years, the number of patients with dry eye in the world has been increasing, and it has reached120,000.

Medical scientists warn that people often don't care because the symptoms of this disease are usually not serious. However, research shows that long-term dry eye will bring irreparable damage, and even lead to blindness in extreme cases, so we should pay enough attention to this disease.

According to the different causes, it can be divided into the following three categories.

1. Solid keratoxerosis conjunctiva: It is caused by extensive scarring of eyelid conjunctiva and bulbar conjunctiva, which destroys the secretory gland of conjunctiva itself, even lacrimal gland and lacrimal passage. Such as severe trachoma, extensive thermal or chemical burns, severe chronic conjunctivitis and pemphigoid.

2. xerophthalmia-arthritis syndrome (or "dry eye syndrome"): this is a disease with unknown etiology, which has only been discovered in recent years and may be caused by congenital immune system abnormality. The main manifestations are keratoconjunctivitis sicca, xerostomia and connective tissue disease (the most common is rheumatoid arthritis).

3. xerosis conjunctivae: this is one of the eye manifestations of vitamin a deficiency. Vitamin A deficiency is mainly caused by high consumption and low intake of vitamin A in the body. It is more common in infants who are improperly artificially fed, and malabsorption or consumptive dysentery such as measles, pneumonia, disease and diarrhea is easy to occur. Adults are more common in patients with advanced liver cancer, liver cirrhosis and long-term chronic digestive tract diseases.

"Dry eye", or conjunctival dryness and keratitis (dry angle, conjunctivitis), is a disease in which the conjunctiva and corneal epithelium can't maintain their normal functions due to the insufficient quality of the tear film before the cornea or the insufficient amount of tears.

Dry eye is a chronic disease for the following reasons:

1. Due to old age, lack of sleep, mental stress and other physiological reasons, the quality of tears decreased.

2. Taking some antihypertensive drugs and some antipsychotics has an effect on tear film. For example, taking chlorpheniramine has a bad effect on tear film. At present, taking propranolol and some birth control pills can reduce the production of tears.

3. Dry rooms and other environments lead to increased evaporation of tears.

4. I have been engaged in computer operation, car driving, reading and other fine operations for a long time, and the number of blinks has decreased.

5. Due to contact lenses, allergic conjunctivitis, air pollution, ultraviolet rays and other reasons, tears are reduced and the quality is reduced.

6. Long-term use of antibiotics, flora imbalance.

If the eyes feel abnormal in daily life, please check whether there is "dry eye". By paresthesia, we mean that patients with dry eye are sensitive to airflow, and they are particularly prone to corneal dryness in windy environments. So, you are much more comfortable indoors than outdoors. When the patient's attention is focused, the blink frequency decreases, and the cornea is exposed to the air for more than the tear film rupture time, so the dryness is particularly obvious. When I wake up at night or early in the morning, my eyes feel dry and serious, because there are fewer tears during sleep. For patients with insufficient tears, smoke is almost unbearable, because smoke itself is powder suspended in the air, which directly impacts the corneal surface and causes discomfort.

In addition, it should be understood that dryness and less tears are not specific symptoms. On the contrary, some people with dry eye will complain about tears or tears overflowing, which may sound contradictory, but in fact, dry eye may stimulate the reflex secretion of tears, just like foreign bodies or abrasions on the eye surface.

In the face of complications such as decreased vision caused by dry eye, which seriously damages eye tissues and may even lead to blindness, the first thing to do is to strengthen prevention in daily life and improve modern people's awareness of self-care for eyes.

One more thing. Personally, I think if you know, you have to know why.

The solution is as follows:

1. You don't want to go to the hospital, but when you find that the symptoms are serious or persistent, you really need to be diagnosed and treated by an ophthalmologist. If it is diagnosed as dry eye, it should be treated with drugs in strict accordance with the doctor's advice; If it is visual fatigue caused by discomfort of glasses or contact lenses, you can reconfigure appropriate glasses according to the prescription of glasses prescribed by ophthalmologists, and pay attention to eye health care in daily life.

2. Paying attention to eye care in daily life can alleviate the symptoms of dry eye, such as paying attention to mental relaxation at ordinary times and taking a proper rest when feeling tired eyes; Try not to look up, put the TV or computer below eye level, watch TV or use the computer for too long; Desk and computer monitors should be placed in places that are not exposed to direct sunlight, because the images of reflected illumination light will cause eye fatigue; Keep the room at a certain humidity.

Of course, the most direct way to solve dryness is to make your eyes moist, and the healthiest way is to yawn. If you can't do it, drop artificial tears.

4. Eat more vitamin A Chrysanthemum is rich in vitamin A, which is an important substance to maintain eye health. Therefore, it is also a good medicine for Chinese medicine to treat various eye diseases. Chrysanthemum tea can make people clear-headed and bright-eyed, especially for dry eye caused by excessive use of eyes. People who often feel dry eyes, especially those who often use computers, might as well drink more chrysanthemum tea.

Are your eyes dry, bloodshot, afraid of light, tearful and even red? If so, it means that your eyes have been hurt. The cause of eye fatigue is generally related to the secretion of tears, which should attract your attention and protect your eyes doubly. It is the most convenient and effective way to add some food that nourishes the eyes to the diet.

vitamin A

Needless to say, vitamin A, known as "eye protection necessities", is a good way to prevent dry eyes, decreased vision and night blindness. Carrots, yellow-green vegetables and red dates are the most abundant.

Vitamin b

Vitamin B is one of the nutritional sources of the optic nerve, and insufficient vitamin B 1 is easy to make eyes tired. Vitamin B2 deficiency is easy to cause keratitis. You can eat more sesame seeds, soybeans, fresh milk, wheat germ and other foods.

Chinese wolfberry

Lycium barbarum has long been effective in clearing liver and improving eyesight, because it is rich in carotene, vitamin A, B 1, B2, C, calcium, iron and so on. It is an essential nutrient for healthy eyes.

Three dietotherapy formulas of Lycium barbarum;

1. Lycium barbarum+rice: adding a little sugar after cooking porridge can treat blurred vision and tears.

2. Lycium barbarum+chrysanthemum: Brewing with hot water can make your eyes relax and bright.

3. Lycium barbarum+pig liver: The soup has the functions of clearing away heat, eliminating eye astringency and eliminating dark circles caused by staying up late.

Cassia seed has the effects of clearing liver-fire, improving eyesight and moistening intestines, and can improve eye swelling and pain, redness and tears, and prevent visual impairment.

Learn to sleep.

Do you know that?/You know what? Do you know that?/You know what? What water to drink before going to bed and the posture of sleeping will affect the eye condition.

1. Don't drink too much water before going to bed, otherwise getting up frequently at night is on the one hand, and it will also cause obvious eyelid edema; In addition, coffee and tea will make the water in the body evaporate quickly, and the eyes will be drier.

Adequate sleep is the best way to eliminate eye fatigue, but pay attention to sleeping posture. Lying on your stomach and sleeping on your side often causes wrinkles at the end of your eyes, or puffiness in your eyes. The correct sleeping position should be supine.

Dry eye is very common in the elderly, mainly due to the decrease of tear secretion and its quality changes. Tears are secreted by the lacrimal gland in the outer upper corner of the eye and act on the surface of the eyeball by blinking to keep the eyes moist and smooth. In addition to water, tears also contain mucus and fat, which will remain on the corneal surface for a long time. The imbalance of these components in the elderly and the easy disappearance of tear film are also one of the reasons for dry eyes. The prevention and treatment methods are: pay attention to protect the eyes and avoid strong light and high temperature stimulation; Don't spend too much time reading, watching TV or computer screen; Atropine drugs that inhibit gland secretion are prohibited; Intermittent supplementation of cod liver oil pills or regular consumption of liver and pig liver food; Also taking Qiju Dihuang Pills; If the symptoms of dry eye are serious, ophthalmologists can use artificial tears or 1% methylcellulose eye drops.

Treatment prescription for dry eye and eye fatigue

Do you often feel dry, sore and tired when using the computer, reading books and watching TV? Excessive eye use caused by long-term eye use is a major cause of eye fatigue. The common symptoms of eye fatigue are blurred vision for a long time, some can't even write or read, dry eyes, dizziness and pain, and even nausea and vomiting in severe cases. In addition, visual fatigue can also lead to myopia or presbyopia in adults, and eye diseases such as cataract, glaucoma and retinal detachment can also be accompanied by overuse of eyes.

To protect eyes, prevent eye damage and relieve eye fatigue, besides proper lighting, correct operating posture, rest and eye exercises, it is also important to supplement nutrition for eyes.

Modern medical research shows that vitamins are closely related to the occurrence of eye diseases and visual quality. People who overuse their eyes need more vitamins and minerals. It is very important to supplement the nutrients needed by eyes reasonably to protect eyes, prevent eye trauma, prevent eye diseases and improve eyesight.

Therefore, people with eye fatigue should pay attention to the balance between diet and nutrition, and usually eat more coarse grains, miscellaneous grains, red and green vegetables, potatoes, beans, fruits and other foods containing vitamins, protein and cellulose. Now I will introduce two remedies for dry eye for your reference.

1, black bean walnut milk:

Ingredients: black bean powder 1 spoon, walnut paste 1 spoon, milk 1 bag, honey 1 spoon.

500 grams of black beans, fried, cooled and ground into powder. 500 grams of walnut kernel, slightly fried, stripped, cooled and mashed into mud. Take the above two foods 1 spoon, pour them into 1 cup of boiled milk, and then add 1 spoon of honey. Take it every morning or after breakfast, or with breakfast.

Efficacy Black beans are rich in protein and vitamin B 1. The nutritional value is very high. Because black food enters the kidney, combined with walnut kernel, it can increase the strength of tonifying kidney. Together with milk and honey, these foods contain more vitamin B 1, calcium, phosphorus and so on. , can enhance the muscle strength in the eye, strengthen the regulation function and improve the symptoms of eye fatigue.

2. Gouqi porridge

If people with visual fatigue can take it for a long time, twice a day in the morning and evening, it will not only eliminate the symptoms of eye fatigue, but also enhance their physique.

Eye-friendly food

To protect your eyes, in addition to paying attention to the combination of work and rest, don't read books, watch TV and do eye exercises for a long time. Eating some food that is good for your eyes can also play a great role in protecting your eyes. So, what foods are good for the eyes?

The first is lean meat, poultry, animal offal, fish and shrimp, milk, eggs, beans and so on. , which is rich in protein, and protein is the main component of cells, so tissue repair and renewal need to constantly supplement protein.

Secondly, foods containing vitamin A are also good for the eyes. When vitamin A is deficient, the adaptability of eyes to dark environment decreases, and it is easy to suffer from night blindness in severe cases. Taking enough vitamin A every day can also prevent and treat dry eye. The best source of vitamin A is the liver of various animals, while plant foods, such as carrots, amaranth, spinach, leeks, green peppers, sweet potatoes with red hearts and oranges, apricots and persimmons in fruits, etc.

In addition, eat more foods containing vitamin C. Because vitamin c is one of the components that make up the lens of the eyeball. If vitamin C is lacking, cataract with turbid lens will easily occur. Foods rich in vitamin C include all kinds of fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, Chinese cabbage, fresh dates, pears and oranges.
