So what causes dry eye syndrome? First, let's learn about human tears. There are three main parts to human tears: the lacrimal gland produces most of the tears, the meibomian gland produces a component of tear oil, and the goblet cells maintain all parts in combination. When one of these glands is out of balance, people will experience eye disorders.

Dry eye syndrome is mainly caused by inadequate tear production or poor quality tears. Inadequate tears are mainly caused by inflammation of the lacrimal glands, and poor tear quality is caused by meibomian gland dysfunction, and inflammation of the glands at the margins of the eyelid.

The following factors can cause people to develop dry eye syndrome. First, if people have some systemic disorders such as rheumatoid arthritis and acne rosacea, they are more likely to have dry eyes.

Second, one of the common complications of refractive surgery is dry eyes, so people have to take care of their eyes after surgery.
