The long-term use of some cosmetics or eyedrops is also the reason. The office of dry eye under normal circumstances cause eye blink 20 per minute to 25 times; when we are reading and watching the computer screen, the number of eyes consciously blink in virtually reduced to 5 to 10 times, the exposed eye surface area broadening. This not only reduces the secretion and replacement of lubricating eye tear, and ocular surface exposed to air for a long time due to excessive evaporation too fast, causing dry discomfort. In particular, long-term work in the open air and the air is not smooth in the environment, and often engaged in work activities in high concentration (for example, work in front of a computer screen reading, watching TV and video in a dark room and watching TV, short distance driving vehicles), long-term to prone to dry eye, severe cases can damage the cornea, even cause infection; Xiaowei is a reason.

The lack of such as primary lacrimal gland diseases, congenital abnormal tear, autoimmune diseases, AIDS, trachoma, burns and radiation control and lacrimal gland nerve was damaged and the noise and air pollution, and topical drug use.
