I can see that you have got some trouble recently, dry eyes could be generated by a lot of reasons, such as a lack of sleep, less blink of eyes, or some infections with your eyes. If you constantly have dry eyes, then you should figure out what precisely resulted in that problem. Here I got some advice for you. First of all, try to blink more and get sufficient water. Second, try to have breaks during business hours or entertainment hours. Also, try to get a healthier diet and take some vitamin pills. If the problem does not change, then a doctor would be necessary.
