Fall is comfortable but dry, some of the white-collar workers who work on the computer every day began to feel dry eyes, eye heat, see things unclear, and in some cases, itchy. Regular use of computers in a dry, uncirculated environment, increased surface area of the eye exposed between blinks and a decrease in the number of blinks can accelerate the evaporation of tears and become one of the triggers of dry eye syndrome. The number of dry eye patients increases during this season, so it is important for people to pay attention to eye protection when working at this time. Dry eyes occur easily due to reduced blinking The normal eye surface is covered with a layer of tear film, and a stable tear film is the basis for maintaining the health of the eye surface. Tears not only disinfect and sterilize, but also lubricate the eyeball and maintain the important function of the corneal refractive system. Blinking is a protective neurological reflex that allows tears to evenly coat the surface of the cornea and conjunctiva to keep the eye moist but not dry. Normal people blink about 20 times per minute, if the eyes are open for a long time to stare at the screen of rapid changes, the number of blinks is often reduced to four to five times per minute, there will be symptoms of dry and sore eyes. Similarly, if the tear secretion is too little, so that the cornea is always not moist, the whole eyeball dry lightless, corneal epithelium keratinization, there is obvious scar formation, look at things when there is a blurred vision, the eyes have a burning sensation and foreign body sensation, vision fatigue, eye grinding pain, etc. Formation of dry eye syndrome. Five kinds of people are prone to dry eye disease As a common disease, frequent disease, we still do not know much about dry eye disease. Work in front of the computer and have to “enjoy” the central air conditioning of white-collar workers, due to eye diseases need to maintain the point of eye medication patients, long-term contact lens wearers, have done eye myopia, cataract surgery and hormone disorders during menopause in the dry climate because of the tear film evaporation accelerated causes of dry eye. Long-term work in the air conditioning open, air circulation environment, often engaged in concentrated work, such as computers, driving, etc. can cause transient intervals between the exposure of the eye surface area increases and the frequency of transient reduced, so that the evaporation of tears accelerated. Computer workers are mostly working in air-conditioned equipment in a closed environment, due to low humidity, coupled with the computer emits heat, in a dry environment, the tear layer evaporates in a few seconds. The symptoms are: dry eyes, headache, irritability, fatigue, and difficulty concentrating. According to a survey conducted by the National Institute for Occupational Health and Safety, 90% of people who work in front of a computer for more than three hours a day have eye problems. Dry eye patients often have dry eyes, foreign body sensation, photophobia, blurred or fluctuating vision and other discomforts, severe dry eye can cause a significant loss of vision and affect work and life, and even lead to blindness. In the United States, 14.6% of people aged 65 to 84 suffer from dry eye. Based on our sanitary and environmental conditions, the prevalence rate may be higher than that in the United States. Dry eye diagnosis relies on symptoms In the diagnosis of dry eye, great emphasis is placed on the patient’s symptoms. As long as symptoms are present, the patient may be diagnosed with dry eye even if the objective tests are negative. If the objective test is positive, but the patient does not feel anything, the diagnosis of dry eye should be cautious. Dry eye can be categorized into tear-deficient dry eye and hyper-evaporative dry eye. One is caused by a decrease in the amount of tears people produce, and the other is caused by an abnormal quality and quantity of lipids secreted by the blepharoplastid glands, which accelerates evaporation of the normal tear film on the surface of the eye. Many patients like to “treat” themselves when they begin to have eye discomfort, using antibiotics and antiviral eye medications. In fact, this method is not suitable for the treatment of dry eye, but may aggravate the symptoms, because the treatment of different types of dry eye is not the same. If dry eye is caused by taking certain medications, the medications should be stopped; if it is caused by immune diseases, endocrine disorders, vitamin deficiencies, etc., the above diseases should be treated first. Tear-deficient dry eyes need to order artificial tears, when uncomfortable, but it is best not to do so more than 6 times a day, because if it is more than 6 times, the normal tear film will be washed away, thus aggravating the symptoms. If diagnosed by the doctor is blepharoplasty dysfunction patients should pay attention to eyelid cleaning, every day with a towel dipped in water higher than the body temperature but do not be too hot to close the eyes on the eyes, each time for about 10 minutes, the best thing to do in the morning, if there is time a day can be done several times, the effect will be better, but also can be asked to the medical staff for massage. After the emergence of dry eye, both antibiotic eye drops, hormone eye drops, artificial tears and the use of drugs for the treatment of seborrheic dermatitis should be carried out under the guidance of a specialist.
