Many friends usually have tears in the wind, but when they go to the hospital, the doctor tells them that it is dry eye, which is puzzling, why is it obviously tears, but diagnosed as dry eye? In fact, there are two forms of tear secretion, one is basic secretion and the other is stress secretion. The basic secretion of tears, though small in quantity, is always going on and is the main way to moisten the eye, so basic secretion is extremely important and is also the main object of examination for doctors to diagnose dry eye. This type of secretion is also known as “tearing in the wind”. Although the amount of tears secreted by this type of secretion is so large that they often overflow from the eye sockets and form visible tears, it is not always present, so it cannot replace the basic secretion and lubricate the eyes permanently. In people who suffer from dry eye, the basic secretion of tears is often low, and the evaporation rate of tears is fast. This is the reason for the formation of the so-called “tears in the wind”. In fact, this phenomenon does not necessarily appear after the “wind”, any factors that can accelerate the volatilization of tears, can cause the so-called “tears”, so I hope that such friends in the discovery of their “tears Therefore, I hope that these people will think carefully when they find themselves “tearing”. Do not use eye medication or receive the wrong treatment.
