Dry autumn pay attention to protect eyes
Although the autumn is comfortable and dry, some white-collar workers who work on the computer every day start to feel dry, the eyes are hot, the things are clear, and some are itchy.
Experts believe that computers are often used in air-dry, non-circulating environments. The number of exposed eyes and the number of blinks between the two blinks are reduced, and the evaporation of tears accelerates and becomes one of the causes of dry eye syndrome.
This season, the number of patients with dry eye has increased, so at this time, people must pay attention to the protection of the eyes when working.
銆€銆€鈻?Due to the reduced number of blinks, eye dryness is easy. Associate Professor Wang Yanling, director of the Eye Hospital of Friendship Hospital, said that the normal eye surface is covered with a tear film, and the stable tear film is the basis for maintaining the health of the eye surface.
The tears completely disinfect and sterilize, as well as lubricate the eyeballs to maintain the important function of the corneal refractive system.
Blinking is a protective nerve reflex that allows tears to be applied evenly over the cornea and conjunctiva to keep the eyeballs dry rather than dry.
A normal person blinks about 20 times a minute. If you repeatedly open the eye and change the screen quickly, the number of blinks is often reduced to four to five times per minute, and the symptoms of dry eyes and sores may appear.
Similarly, if the secretion of tears is too small, the cornea will never get wet, the whole eyeball will be dry and dull, the corneal epithelium will be keratinized, and obvious traces will form. When looking at things, there will be unclear vision, and the eyes will have a burning sensation and foreign bodies.Feeling, visual fatigue, eye pain, etc. form dry eye syndrome.
銆€銆€鈻?Five kinds of people are prone to dry eye syndrome. Director Wang introduced that as a common disease, it is frequently ill, and everyone knows little about dry eye syndrome.
Working in front of the computer, you must “enjoy” the white-collar workers in central air-conditioning, patients who need eye medicine for eye diseases, people who wear contact lenses for a long time, people who have had eye myopia, cataract surgery and menopausal hormone levels in a dry climate.In the middle of the city, dry eye syndrome is caused by the evaporation of the tear film.
銆€銆€For a long time, the air conditioner is open and the air is not in the environment. It is often concentrated and concentrated. For example, using computers, driving, etc. can cause eye enlargement and transient frequency reduction during transient interval exposure, which accelerates the evaporation of tears.
Computer workers work in a confined environment with air-conditioning equipment. Due to the low humidity and the heat generated by the computer, the tear layer evaporates in a few seconds in a dry environment.
Symptoms are: dry eyes, headache, irritability, fatigue, and difficulty concentrating.
According to a survey by the National Institute of Occupational Health and Safety, 90% of people who work more than three hours a day in front of a computer have problems with their eyes.
銆€銆€Patients with dry eye often have dry eyes, foreign body sensation, photophobia, blurred vision or distorted discomfort. Serious dry eyes can cause significant decline in vision and affect work and life, and even lead to blindness.
In the United States between the ages of 65 and 84, 14.
6% suffer from dry eye syndrome.
Depending on routine hygiene and environmental conditions, the incidence may be higher than in the United States.
銆€銆€鈻燚ry eye syndrome diagnosis of persistent symptoms In the diagnosis of dry eye syndrome, the symptoms of the patient are very indicated.
As long as there are symptoms, even if the objective test results are consistent, it may still be diagnosed as dry eye.
If the objective examination is positive, the patient does not feel it, and it is necessary to be cautious if it is diagnosed as dry eye.
Dry eye syndrome can be divided into tear-deficient dry eye and evaporative dry eye, one is due to the decrease in the amount of tear secretion, and the other is due to the abnormal quality and amount of adenine secretion from the meibomian plate.The tear film evaporates faster, causing dry eyes.
銆€銆€Many patients like to “treat” themselves when they start eye discomfort. They use antibiotics and antiviral eye drops. In fact, this method is not suitable for the treatment of dry eye syndrome. Instead, it may aggravate the symptoms because of different dry eye treatments.The method is different.
If you take some medicines and cause dry eye, you should stop the medicine; if it is caused by immune diseases, endocrine disorders, vitamin deficiency, etc., you must treat the above diseases first.
銆€銆€The tear-deficient dry eye needs artificial tears. When it is uncomfortable, it is better, but it is better not to exceed 6 times a day, because if it is more than 6 times, the normal tear film will be washed away, which will aggravate the symptoms.
銆€銆€If the patient diagnosed with meibomian gland dysfunction by the doctor should pay attention to the eyelids clean, use a towel dipped above the body temperature, but do not put too hot water on the eyes, every 10 minutes or so, it is best to do it in the morning.If you have time to do it once a day, the effect will be better, you can also ask the medical staff for a massage.
銆€銆€Since the establishment of the dry eye specialist clinic in the Friendship Hospital, there have been many patients visiting the hospital, but when communicating with patients, doctors have found that there are many misunderstandings.
In order to prevent this disease, experts reminded to pay attention to eye hygiene, including accidentally blinking, use the eyes to rest for an hour or so, close your eyes and look forward to the distance; do more eyes when doing more attention.
銆€銆€After the onset of dry eye, the use of antibiotic eye drops, hormone eye drops, artificial tears and the treatment of seborrheic dermatitis drugs should be carried out under the guidance of a specialist.
