2. What Causes Dry Eye?

Dry eye syndrome occurs when the tear production process is disrupted. This can happen for myriad reasons including hormone changes and side effects of medication. The former plays a large role in dry eye, especially in women, because hormones and the nervous system are intrinsically involved in tear production. Age is another common cause, as everyone produces fewer tears as they age. Additionally, environmental factors such as weather exposure, reading, and computer use can cause dry eye.
