Excessively catch the eyes disease with the eyes
It is hot, eyes are no longer bright and intelligent. Especially the intersection of computer and clan or clan of driving, reduce the number of times of blinking while being excessive with eyes, combine with the dryness of the environment, it will be more and more sensitive that eyes do the astringent uncomfortable sense. It turns hot, the tear is easier to evaporate than autumn and winter. The oculist finds too, because eyes be the astringent patient who go to a doctor to increase much. Because it is moist so long as the eyeball has no tear in 10 seconds, a part of leather cells will become dry on the cornea, the serious one cornea will also present the ulcer, damage. So, often feel eyes are dry the astringent one can't be careless. Dr. Chen YueGuo, ophthalmology associate professor of treatment of No.3 Hospital of BJ Medical University, introduces, there is tears membrane that a layer of tear formed on the surface of eyeball, can make eyes keep wet, if the tear is distributed irregularity, eyes will feel that do the astringent discomfort. Eyes will also have a sense of foreign matter, canthus secretion that increase at the same time, when especially or drive, make the computer in the air conditioner room, also will feel eyes are uncomfortable. Dr. Chen emphasizes, the reason of the above-mentioned symptoms is mainly while making the computer or driving that appears, attention is concentrated very much to make to blink the number of times is reduced, will generally reduce by about 10%, reduce 14 times of every minute to for 5 times, having reduced the production of the tear, and the eyeball uncovers in the dry air environment for longer time, make the eyeball moisture content evaporate too fast, it is very apt to cause eyes to do the astringent discomfort. Combine with eyes always in overstrain state, the skin of eyes will be overtired, cause a great deal of uncomfortable senses of eyes; If eyes formed by the fact that the tear secretes insufficient, poor quality do the astringent discomfort, suffered from dry eyes. Need to be diagnosed by the oculist, make a definite diagnosis of. Dry eyes are often caused by lacking, sequela and immune system question of the trachoma of vitamin A. It is introduced, the composition of the tears is besides water, the function that the helpful cornea grows too, so eyes have not secreted the tear or blinked like 10 seconds the number of times is reduced, the tear is evaporated too fast, the cornea will begin to feel dry, under the microscope, the originally transparent cornea makes like " frosted glass " The same. In addition a noteworthy one is, as to the person wearing the contact lenses for a long time, because cornea acuity becomes low, perhaps difficult feeling eyes are different, will come down for a long time, not merely damage of cornea, even will punch, influence eyesight seriously. So Chen YueGuo Dr. propose no matter eyes that hygiene cause do astringent or suffering from the intersection of dry eyes and disease real with eyes, need to moisten skin with artificial tear. As to the thing that general eyes do astringent and getting uncomfortable, don't use a long time such as eyes, overlooking outside the window and paying attention to, blinking number of times frequent continuously, and then supplement the artificial tear a bit, symptom will be relieved even disappeared; And to real dry eyes, all need help of artificial tear all one's life. The generally bottled artificial tear contains preservatives (foreign artificial tear is generally labelled) ,It will stimulate cornea cells, so should choose not including the tear of preservative of inner wrapping, such as 1 ml, almost can use up in one day. In addition, in daily life, pay attention to avoiding staying in the dry, windy environment for a long time; Put the intersection of basin and water in the intersection of air conditioner and room, can use the humidifier to keep the indoor humidity while being conditional. The clan had better click and use the artificial tear before setting out to often drive, in order to keep eyes wet, protect the cornea. Besides artificial tear, Dr. Chen emphasizes, commercial eye drops can't be bought and abused at will by oneself, especially include ophthalmic medicine of hormone or antibiotic, need to use under the guidance of specialist. Because include ophthalmic medicine of hormone or antibiotic, it is very apt to cause eyes fungus group to lack proper care, the fungi grow and breed fast, eyes send out a warning healthily.
