Do I have dry eyes? Why do you get dry eyes?

Dry eye syndrome will basically appear different degrees of dry eyes, but also appear photophobia, if trachoma, the mucosal blood vessels in the eye are blurred, and there are many small protruding bumps with astringent itching, and the symptoms of erythromycin ointment are relieved. At present, there is no conclusive evidence that myopia surgery has major sequelae, and it is still possible to do it within 400 degrees.

The eyes are the essence of the five internal organs, if the qi and blood are insufficient, the fluid is depleted, and the eyes are not nourished, it shows dry eyes, it is recommended to see a Chinese medicine doctor, take decoction or use acupuncture**, the effect is very good!

We know that in daily life, many people don't know why they get dry eye syndrome after they get dry eye syndrome, and they feel that they usually don't use their eyes excessively, and they also protect their eyes very well, but they just have dry eye syndrome.

In fact, there are many reasons for the onset of dry eye syndrome, not only excessive eye use is one reason, but the onset of many dry eye syndromes is often closely related to systemic diseases, such as Sjögren's syndrome, systemic lupus erythematosus or rheumatoid arthritis and Behcet's syndrome, which is also very easy to be complicated by dry eye syndrome. Therefore, if you have dry eyes, you must go to a rheumatology and immunology department to rule out the possibility of these rheumatic immune system diseases.

Of course, with the wide application of mobile phones and computers, excessive eye use is the direct cause of dry eye syndrome, but if you do not pay attention to eye cleanliness at ordinary times, frequent eye makeup or frequent tattoos and contact lenses are also very easy to lead to the onset of dry eye syndrome.

Symptoms of Dry Eye Syndrome:

Dry eye symptoms vary widely from person to person. Most patients complain of a foreign body sensation in the eye, a burning sensation and general ocular discomfort. These discomforts are typically described as scratching, dry eyes, pain, gritting, tingling, or burning.

These discomforts are often evidence of dry eye because the surface of the cornea is full of sensory nerve endings. A significant proportion of patients have photophobia, intermittent blurring or other vision problems.

People with dry eye often complain that their eyes get tired easily, making it difficult to read and watch television. The reason for these difficulties is that the frequency of blinking is significantly reduced when the work requires concentration. When the frequency of transient eyes is significantly reduced, the time for tear film to evaporate will be significantly longer.

If blink is insufficient, the corneal conjunctiva will be exposed for longer than BUT, resulting in the formation of one or more dry spots on the corneal surface.

Inability to tolerate the wearing of contact lenses is also a symptom of dry eye. Sometimes, a patient with mild or moderate dry eye will not experience significant discomfort without contact lenses. Wearing contact lenses can disrupt the balance of tear film secretion and distribution, resulting in inability to tolerate contact lenses; Now see for yourself whether this is written and your symptoms are not like!

What is dry eye syndrome:

"Dry eye syndrome" or dry conjunctiva, keratitis is a disease caused by the lack of quality or quantity of the precorneal tear film, the conjunctiva and corneal epithelium can not maintain normal function, the tear film is composed of a very thin surface lipid layer and an aqueous layer rich in polysaccharide proteins and mucin, the lipid layer has the effect of delaying the evaporation of the tear film, under the condition of 30% relative humidity, the evaporation rate of the tear film is 3m h, the evaporation decreases when the humidity is high, and the evaporation increases when dry.

Dry eye syndrome is a chronic disease, people with this disease often suffer in life, and its causes are not as noticeable as trauma and internal diseases, the causes of dry eye syndrome are as follows:

1. Due to physiological reasons such as advanced age, lack of sleep, and mental stress, the quality of tears decreases.

2. Taking some antihypertensive drugs and some neuroleptics has an effect on tears, such as taking chlorpheniramine has a harmful effect on tears, propranolol and some contraceptives can reduce tear production.

3. Due to long-term computer operation, car driving, reading and other fine operations, the number of blink eyes decreases, causing tears to decrease.

The eye is extremely important to human beings, it is the most important organ of the human senses, almost all knowledge needs to be obtained through the eye, so the health of the eye is particularly important, especially for diseases like dry eye syndrome, which can cause blindness. Dry eye syndrome is a comprehensive disease, which is generally caused by insufficient tear secretion and decreased mucin secretion. So, what causes dry eyes?

1. What causes dry eye syndrome?

1. Lack of vitamins: If there is a lack of vitamin A in the human body, it may lead to dry eye syndrome, and the lack of vitamin A in the human body will cause insufficient secretion of ocular mucin, resulting in dry eye syndrome; Proper vitamin supplementation can alleviate dry eye conditions.

2. Age is too high: most people who suffer from dry eye syndrome are middle-aged and elderly people over 45 years old, because their own hormone levels decline, the body's endocrine function will decline, resulting in dry eyes; If you want to relieve the situation, you can pay attention to the usual time of eye use, exercise more, improve the body's endocrine function, and cooperate with a proper diet to get relief.

3. Working environment: For office workers, the most common thing to use every day is to use the computer, and facing the computer for a long time will cause tears to evaporate too quickly, causing a low frequency of blinking, and will also form dry eyes; In addition, long-term blowing of air conditioners by office workers will also accelerate the evaporation of tears, causing dry eyes.

4. Drug reasons: If the patient suffers from hypertension, arthritis, diabetes, and is taking drugs to alleviate it, it will lead to a decrease in tear secretion, and if antibiotics or eye drops are used at this time, it will easily induce dry eye syndrome.

2. How to prevent dry eye syndrome?

1. Eye habits: Dry eye syndrome is mainly caused by pressure imbalance and inattention to the eyes, so if you want to prevent dry eye syndrome, you must let your eyes get proper rest and not be in a state of stress all the time. In study or work, keep a reasonable distance between your eyes and books, computers, mobile phones, etc., and relax your eyes for about half an hour of work, you can look at the food outside the window, turn your eyes, and relieve yourself for ten minutes.

2. Diet: The prevention of dry eye syndrome can be prevented by eating foods that are beneficial to the eyes, such as pumpkin, which is rich in carotene and vitamins, which can play a certain role in the formation of eye pigment and is also a very good antioxidant; The zeaxanthin and lutein in corn can also protect the optic nerve and can alleviate dry eye syndrome.

This disease is an ocular manifestation of systemic nutritional disorders and vitamin A deficiency. The reasons are as follows: 1. Insufficient intake:

Such as improper feeding of children. or insufficient intake due to "food avoidance" during illness. 2. Malabsorption:

For example, indigestion, gastroenteritis, dysentery, etc. can affect the absorption of vitamin A, and the deficiency of vitamin A can cause lesions of the intestinal wall epithelium, thus forming a vicious circle. 3. Excessive consumption: The body grows and develops rapidly in early childhood, and the need for vitamin A is greater.

When suffering from diseases such as measles, pneumonia, whooping cough, etc., the consumption of vitamin A increases.

Dry eye syndrome is greatly related to eye fatigue, and there are many diseases that can cause dry eye syndrome. Therefore, it is recommended that patients try not to look at electronic products at ordinary times and let their eyes rest more. Symptoms of dry eye can also be relieved by warm compresses, and eye drops can be used to relieve severe conditions.

Usually you can use chrysanthemums or wolfberries to soak in water to drink.

Hello, there are many factors that cause dry eye syndrome: such as poor eye use, environmental factors, age factors, and genetic factors.

How to prevent dry eyes.

1) The best way to effectively prevent dry eye disease is to develop the habit of blinking more. Professionals believe that dry eye disease is a stress-type condition that causes the problem of the eyes staring in one direction for a long time. Therefore, the best way to avoid eye strain is to take proper rest and avoid continuous operation.

If you are an eyewear person, it is important to have the right pair of glasses. If you are over 40 years old, it is best to wear bifocal lenses or glasses with a lower prescription when typing. The working posture and distance are also very important, try to keep a distance of 60cm, adjust the most appropriate posture, so that the line of sight can be kept downward about 30o, such an angle can relax the muscles and minimize the area of the surface of the eye exposed to the air.

2) Those who have been engaged in computer operation for a long time should eat more fresh vegetables and fruits, and increase the intake of vitamins A, B1, C and E. In order to prevent corneal dryness, dry eyes, vision loss, and even night blindness, computer operators should eat more foods rich in vitamin A, such as soy products, fish, milk, walnuts, green vegetables, Chinese cabbage, water spinach, tomatoes and fresh fruits. Vitamin C can effectively inhibit cellular oxidation.

The main role of vitamin E is to lower cholesterol, remove waste from the body, and prevent cataracts. Walnuts and peanuts are rich in vitamin E.

Vitamin B1 can nourish the nerves, and green leafy vegetables contain a lot of vitamin B1. You can drink green tea appropriately every day, because the lipopolysaccharide in tea can improve the hematopoietic function of the body, and tea also has the function of preventing radiation damage.

3) In order to avoid the reflection or unclear of the fluorescent screen, the computer should not be placed on the opposite side or back of the window, the ambient lighting should be soft, if there is a window behind the operator, the curtain should be closed, to avoid the bright light directly irradiated on the screen to reflect the bright image and cause eye fatigue. Typically, the average person blinks less than 5 times per minute will dry out their eyes. A person blinks only one-third as often as they normally do when working in front of a computer, thus reducing the secretion of lubricants and enzymes in the eye.

You should blink more often and rest your eyes at least once every hour.

4) In order to reduce the dryness of the eyes, corneal nutrient solution can be used at the eye spot. Such as: Bei Fushu eye solution, Xiao Laiwei eye solution and some artificial tears.

In addition, eye exercises can also play a role in relaxing eye adjustment and reducing eye fatigue. The essence of eye exercise is self-massage, that is, through self-massage of the acupuncture points and muscles around the eyes, increase blood circulation in the eye socket, improve neuronutrition, can eliminate excessive congestion in the brain and eyeballs, due to smooth circulation, intraocular adjustment muscles can eliminate the accumulated metabolites, to achieve the purpose of eliminating eye fatigue.

Therefore, it is important to remind everyone that when you are fully focused on the computer screen, you will blink less often. It is recommended that you blink more often to ensure that the "tear sheets" can disperse moisture to the cornea and prevent dry eyes. If you suspect that you have dry eyes, you should seek medical attention as soon as possible.

Dry eye syndrome is clearly distinguished, moderate and severe. Generally clear, moderately with some artificial tears, pay attention to the rational use of eyes, eat more vegetables and fruits can be relieved. Severe cases require surgery**. At present, the latest surgical methods in China include supramaxillary gland and parotid gland transplantation.

Dry eye syndrome can cause eye congestion, dry eye patients, because the cornea is never moistened with tears, the whole eye is dry and dull, corneal epithelial keratinization has obvious scarring, there will be blurred vision when looking at things, burning sensation in the eyes, foreign body sensation, visual fatigue, membrane pain and other symptoms, severe eye pain, eye swelling, photophobia, eye redness and so on.

Signs of dry eye syndrome include dilation and hyperemia of the bulbar conjunctival vessels, loss of luster of the bulbar conjunctiva, dryness and dullness of the cornea, thickening and edema, wrinkling, narrowing, or interruption of the bulbar conjunctiva, sometimes a yellowish viscous discharge in the lower fornix, and varying degrees of punctate detachment of the corneal epithelium in the palpebral fissure.

In the early stage of dry eye disease, it mildly affects vision, and after the disease develops, filamentous keratitis can appear, and the symptoms evolve into intolerable, and corneal ulcers appear, corneal thinning, and even endophthalmitis secondary to perforation, etc., and corneal scarring seriously affects vision.

I don't think you need to do anything about it, the main thing is to pay attention to protecting your eyes, after looking at the computer for a long time, the eyes such as books will feel dry, look down at the distance when you are tired, rest more, do eye exercises, and eat some food that is good for your eyes.
