Xiao Lu, who works as a clerk in a foreign company, stays in a warm office building in winter and cool in summer, facing the computer almost every day. She has always had dry eyes, red eyes, itchy eyes and foreign body sensation. In order to save the trouble of going to the hospital, on the basis of experience “self-initiated” to the nearest pharmacy to prescribe the right medicine, long-term point with a large number of “anti-inflammatory” eye drops, but know that the symptoms not only did not ease, and dry eyes and eye itching and other feelings continue to aggravate, and rushed to the hospital, After examination, it was found that dry eye was the cause of the problem, not only her tear film was unhealthy, but also there were multiple epithelial erosions on the cornea, and it was only after the doctor’s timely treatment that her symptoms were significantly relieved. In life, there are really many patients like Xiao Lu, many people subconsciously believe that dry eye disease is a minor illness. Dry eyes, make up some eye drops is not on the line. As long as the eye discomfort on a few drops of eye medicine, the surface is very convenient. Unbeknownst to you, there are many eye diseases that cause dry eyes, and dry eyes are even a symptom of some systemic diseases, and the treatment for different types of dry eyes is not the same. Moreover, most eye drops contain preservatives, which can damage the cells on the surface of the eye and aggravate the symptoms of dry eye. In outpatient clinics, we often encounter patients who buy eye drops from pharmacies on the basis of their own experience and use them incorrectly, causing minor diseases to become major, minor diseases to become serious, and long-term treatment. Some patients even suffer from glaucoma, corneal ulcers, cataracts, vision loss and blindness due to long-term use of eye drops containing hormones. Therefore, when you suffer from dry eye, you should not order eye drops by yourself. So how do we deal with dry eye? Is it possible to use a certain kind of eye drops and get rid of it? First of all, we should know that the reason why normal eyes can remain black and white and look watery and crystal clear is inseparable from the moisturizing and protective effect of tears. Tears form a thin, clear, liquid film on the surface of the eye – the tear film. It consists of three structural layers. The outermost layer is the lipid layer, which prevents tears from evaporating quickly; the middle layer is the aqueous layer, which mainly plays the role of moistening; the innermost layer contains mucin that keeps the tear film and corneal epithelium tightly together. Under normal conditions, tears evaporate and are absorbed at a certain rate, while the tear glands continue to secrete fresh tears for replenishment, thus ensuring the normal structure of all layers of the tear film and maintaining the health of the eye surface. When various reasons cause abnormal tear quality and quantity or distribution, resulting in tear film instability, dry eye occurs, with discomfort such as dryness, foreign body sensation, burning sensation, eye itching, eye redness, occasional stinging, heavy eyelids, blurred vision, easy fatigue and soreness. The discomfort is worse in the afternoon, evening or when the eyes are used for a long time, and is more unbearable in hot, windy and dry weather or low humidity environments. Dry eye can be divided into those with insufficient tear production and those with excessive evaporation. Many diseases can cause dry eye. Common eye diseases include severe trachoma, recurrent keratoconjunctivitis, blepharitis, ocular surface burns, trauma, etc. In addition, prolonged wear of contact lenses, long-term use of eye drops containing preservatives, and after eye surgery such as myopia laser treatment or cataract removal, dry eye is also prone to occur. Certain systemic diseases, such as hyperthyroidism causing proptosis and vitamin A deficiency, can cause dry eye to varying degrees; it is worth noting that dry eye is also an important symptom of some chronic autoimmune diseases, such as rheumatoid arthritis and the so-called dry syndrome with the triad of dry eye, dry mouth and arthritis. In addition to the diseases mentioned above that can cause dry eye, the common causative factors in life are mainly aging, lack of sleep, mental stress, environmental pollution, etc. In recent years, “dry eye” as a worrying fashion eye disease is quietly coming to us. People’s work and entertainment and television, computer contact more and more, facing the fluorescent screen and monitor, due to the dual role of prolonged eye open gaze and computer radiation, the number of eye blinks will be invisibly reduced, and at the same time, due to prolonged exposure of the eye to the air, so that the evaporation of tears accelerated, so that the cornea can not be fully moistened, resulting in eye dryness discomfort, long-term so easily caused by dry eye syndrome, that is, the so-called fluorescent screen syndrome. At the same time, in the office or at home, prolonged use of air conditioning, will also make the eye moisture evaporation too fast, over time will also cause dry eyes, suffering from dry eye syndrome. The treatment of dry eye syndrome is not only to treat the symptoms, but also to treat the root cause. The first step is to look for the cause of the disease through various examinations and eradicate the primary lesion as much as possible, so as to cut off the source of the disease from the root, or at least slow down the progress of the disease. At the same time, the best preservative-free artificial tears should be supplemented appropriately to reduce symptoms, and it is best not to use them too often a day, because if they are used more than 6 times, they will wash away the normal tear film, thus aggravating the symptoms; patients with dry eye of the evaporation-overload type often have lid gland dysfunction, and should pay attention to daily compresses with hot towels, massage in the direction of the lid gland, and clean the lid margin; for those with extreme lack of tears, if necessary, they can be For those with extreme tear deficiency, reversible lacrimal closure can be performed in the hospital if necessary to reduce the frequency of artificial tears by keeping the very limited amount of tears in the conjunctival sac to moisten the cornea. At the same time, we should actively cultivate good eye habits and eating habits in daily life and raise health awareness to prevent dry eye disease as much as possible. Such as the usual eye cleanliness and hygiene; dry season or the use of air conditioning, indoor humidity should be maintained to a certain extent; long-term use of computers or reading process in the middle, keep the environment light soft, the screen clarity should be good, the brightness should be moderate; eye and screen distance should be in 60 cm, so that both eyes flat or mild downward looking at the fluorescent screen, which can make the neck muscles relax, and make the eye exposure area reduced to This will relax the neck muscles and reduce the exposed area of the eye to a minimum, reducing the amount of tear volatilization; rest for 5-10 minutes every hour, try to look far away, relax, and blink more. In addition, you should replenish the nutrition needed by your eyes, eat more fresh vegetables and fruits, and increase the intake of foods rich in vitamin A and B such as carrots, cabbage, bean sprouts, red dates, oranges, tofu, milk, eggs, animal liver, lean meat, etc., and try to eat less spicy and stimulating foods. The health of the eyes is directly related to a person’s ability to work, study, live and many other aspects. It is our goal to let people really understand and know about dry eye and keep it away from our life. For you to open your eyes and feel the freshness of the day, please take care of your eyes and always care for the windows of our hearts.
