Dry eye syndrome usually occurs when **tears are insufficient, tears are excessively dried due to abnormalities in the tear layer, or tears are reduced with age.

In addition, environmental factors such as changes in the weather, increased exposure time to lighting and computers, and decreased blinking are considered representative causes.

Diabetes, rheumatoid arthritis, chronic conjunctivitis, eye examination, thyroid disease, various skin diseases, facial nerve paralysis, or excessive abuse of eye drops can also cause dry eye syndrome. Other factors include LASIK surgery, female hormone reduction, chronic fatigue, stress, and hormonal changes caused by nutritional imbalance.
