To determine the changes in the age composition of patients with dry eye syndrome in recent years, and analyze the correlated agents of age constituent ratio variance in dry eye patients.

The records of 9490 dry eye patients were reviewed in our hospital’s ophthalmology out-patient clinic between June 2010 and June 2015. Four groups were divided according to patients age, ≤30 years old, >30~≤50 years old, > 50~≤70 years old and >70 years old, respectively. The yearly age constituent ratios were compared and analyzed, and the cause constituent ratios in every age group were analyzed.

In 5 years, each age constituent ratio had different variance, and had statistical significance (χ² =77.436, P <0.001). Long time use of video terminal was the highest cause constituent ratio in groups ≤30 years old and >30~≤50 years old.

Changes in lifestyle lead more and more people suffering from dry eyes. Because of unhealthy eye use habits in dry eye patients, the age constituent ratio is increased most obviously below 30 years old, and followed by the 30~50 years old population. It is suggested to avoid adverse factors and away from dry eye.
