The causes of dry eye disease in the general population are very complicated. However, the main causes of the dry eyes of the "net worms" are as follows:

1. Long term use of computer and focus on work and study, reduce blink times and tear secretion;

2. In the dry and dirty air conditioning environment, the eyeball water evaporates too fast. In addition, in the smoke, ultraviolet, air pollution and high temperature environment, the evaporation of tears will also increase, leading to dry eyes;

3. Contact lenses float on tears. Wearing contact lenses will accelerate the evaporation of tears, leading to dry eyes.

The net worms know the cause of dry eye. If you can pay attention to the following details, you can easily avoid dry eye.

1. Pay attention to the working posture and distance in front of the monitor. The monitor and the eye should be kept above 60cm as much as possible, and the most appropriate position should be adjusted so that the line of sight can be kept down about 30-deg.; such an angle can relax the neck muscles and minimize the area of the eye surface exposed to the air. The brightness of the display should not be too bright. Adjust it to half of the maximum brightness. It is better to see the content clearly but slightly darker than the surrounding objects.

When a person works in front of a computer, the blink times are only one third of the normal times, thus reducing the secretion of lubricants and enzymes in the eyes. Therefore, when working in front of a computer, it is necessary to consciously increase the blink times.

7. Hot towel is applied to the eyes for about 10 minutes each time, which can effectively promote the blood circulation of the eyes and relieve dry eye symptoms.

8. Avoid air drying air conditioning environment, long stay in front of the monitor, especially pay attention not to let the air conditioning blow over from the top.
