Persistent dryness, scratching and burning in your eyes are signs of dry eye syndrome. Some people also experience a “foreign body sensation,” the feeling like there’s something in the eye. Occasionally watery eyes can result from dry eye syndrome, because the excessive dryness works to over stimulate the watery component of your eye’s tears. Sometimes the eye doesn’t produce enough tears, or the chemical composition of the tears causes them to evaporate too quickly. Other times dry eye results when you don’t blink often enough. Computer users, for example, often forget to blink for long periods of time, or the monitor is too high so even if their tear film is normal, it eventually evaporates, leading to discomfort.
