After October, the city of Yangcheng had a faint autumn mood. Despite light rain, the autumn weather together dried up the weather. Mr. Sun, who works in the IT industry, felt that his eyes were particularly itchy, dry and astringent. This made him feel very uncomfortable. He had to buy a bottle of eye drops, and dropped one or two drops from time to time.
Eyes are scarce, computer TV mobile phone is the culprit
Professor Lan Yuqing, director of ophthalmology at Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University, said that as soon as he enters the fall, the number of dry eye patients in the eye clinic will increase significantly. This is related to the fact that the weather is dry, windy, and abnormal secretion of tears. People who have long faced computer televisions or smart phones are the hardest-hit areas for diseases, especially when they encounter large dust, smoke, dry environments, long-term flights, air conditioners or hair dryers, and long-term use of eyes. Dry eye can attack. The so-called dry eye syndrome refers to a type of disease caused by decreased tear secretion or excessive evaporation of the tear film. Its symptoms include dry eyes, burning sensation, foreign body sensation, itchy eyes, eye fatigue, etc. There are also a small number of patients with different degrees of eye pain, redness, eye swelling and so on.
Dr. Guo Hui explained that there are mainly the following reasons for the “water shortage†in the eyes:
1) Lack of tears: patients who have congenital tearless, lacrimal gland excision, and sensory nerve palsy; patients with collagen vascular disease can also cause dry eyes, including rheumatoid arthritis, Wegener's granulomatosis, systemic lupus erythematosus, dry synthesis Signs, autoimmune diseases, etc. Some medications such as sedatives, diuretics, antidepressants, antihypertensives, oral contraceptives, morphine, etc., can produce or worsen dry eyes.
2) Dry eye caused by changes in tear composition.
3) Other causes: age older than 40 years old, wearing contact lenses, excimer surgery or other refractive surgery, eyelid disease, blepharitis, rosacea, vitamin A deficiency, trachoma and certain eye drops.
More eye blinking, artificial tears can ease
Prof. Lan Yuqing said that dry eye is not a rare disease, nor does it cause serious discomfort. It is only a small part of daily life. Therefore, many people do not pay attention to it. When symptoms occur, they go to the hospital to buy it. The so-called "eye fatigue" eye drops. In fact, this approach is not proper. Many eye drops on the market are unclear, and if they contain hormones, long-term overuse can cause eye damage. For mild to moderate patients, the use of supplementary tears, such as artificial tears, is the most important treatment that can reduce symptoms. These preservative-free artificial tears can nourish the eye for a long period of time, thereby alleviating dry eye symptoms. As for inflammation caused by dry eyes, topical use of hormones or immunosuppressive agents. In daily life, avoiding the smoking environment, dust environment and air conditioning environment are beneficial to patients with dry eyes. Compulsory, long-term need for the computer crowd, use a computer for a period of time, can have a purpose blink, give the eye to rest, this can relieve the symptom to a certain extent. You can also eat more fish containing Omega-3 fatty acids, which can reduce the chance of dry eye syndrome. Blepharitis usually coexists with dry eye, so using a mild facial cleanser to clean the eyelids and hot eyelids sooner or later also helps to improve the symptoms. Eat more fruits and vegetables, Dr. Guo Hui warned that many people suffering from dry eye, itchy eyes, can not help but rub with their hands, this is actually a taboo dry eye, it will stimulate the eyes, aggravate the symptoms It should be avoided.
