The female 20.37%, male 6%, female prevalence rate was significantly higher than that of male (χ2=9.42, P <0.001); with the increase of age prevalence rate assumes the trend of escalation (χ2=12.26, P <0.05). Combination of systemic and local disease mainly for diabetes, senile cataract surgery, dry eye prevalence was 35.14% and 57.14% respectively. Poor working conditions and long dry eye with the eye excessive fatigue prevalence was 44.00% and 39.39% respectively. After Logisitc regression, the differences were statistically significant.
