Dry eye syndrome is a kind of dry eyes caused by a variety of internal or external factors. Due to too little tear secretion and too much evaporation, your eyes have a burning sensation and you experience symptoms such as itchiness, photophobia, eye redness, blurred vision or fluctuating visual acuity. Through our survey, we found that the number of office workers who have become dry eye family is increasing rapidly. In the ophthalmology clinic, about one in five people often complain of dry eyes, painful itching, burning sensation, and fatigue, which are all typical symptoms of dry eye, and one obvious feature is that students, computer workers, office workers, and drivers are the majority. The number of dry eye patients is higher in white-collar workers in offices, mainly because the main and secondary tear glands of healthy eyes naturally secrete tears to lubricate the eyeball. If you face the computer for a long time, your eyes are too focused on the display screen, resulting in fewer blinks and rapid evaporation of tears. There is also in the normal we watch TV, night driving, stay up late, reading, plus now the OFFICE are installed with air conditioning system, so the humidity is low, air does not circulate, more accelerated the evaporation of tears. If you do not happen to be a contact lens family, it is even worse, and this is the main cause of the acquired “dry eye syndrome”. In addition, dry eye is also a frequent problem after excimer laser surgery. Many patients feel dry eyes and foreign body sensation after PRK and LASIK surgery. During the examination, it was found that the number of tear secretion was reduced and the tear film rupture time was shortened for a period of time after the surgery. Therefore, dry eye examination should be done before surgery, and patients with more severe dry eye should avoid surgery. The symptoms of dry eye manifest themselves in many ways and for many reasons, for example, many office workers are busy and buy some eye drops from ordinary pharmacies on their own, and very few are able to go to a specialized hospital for consultation. There are also many people who, in order to save time, eye drops into the eyes, temporarily feel comfortable, then think that everything is fine, in fact, such irresponsible behavior will only bring more damage to the eyes. In fact, some of our commonly used eye drops contain preservatives, hormones, and antibiotics, which can cause irreparable damage to the eyes with long-term use! For example, chloramphenicol can cause leukopenia and even aplastic anemia.
