There are some very simple tips to help you reduce this kind of injury-as simple as blinking or averting your eyes.
The factors that affect the health of eyes include that the screen is too dazzling or reflective in low illumination, and the blink frequency is not enough to cause dry eyes, which will lead to eye pain.
When you are staring at the computer screen, you can rest your eyes from time to time, and rest every hour or so, so that your eyes can get a proper rest and look at the distance.
The suggestions are as follows:
1. Select a computer monitor that can tilt or rotate and has the function of adjusting contrast and brightness.
2. Use an adjustable computer seat.
3. Put the reference materials to be used on the file rack next to the computer, so that you don't need to turn your neck and head back and forth, and your eyes don't need to adjust the focal length frequently.
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. According to your situation, first of all, you should pay attention to the rest time, eye time, rest in the middle, and try to reduce the close contact with the computer.
We should pay attention to this disease at ordinary times, otherwise long-term illness will easily cause damage to our eyes and even blindness. If the eyes have a burning sensation, or if the eyes are red and have a foreign body sensation, they 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.
Because the symptoms of this disease are usually not serious, people often don't care. 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. Personally, if you know more, you should know why. Here are the solutions:
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, and if you can't get it out, you will 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.
