AIM: To analyse the prevalence and risk factors of dry eye among children aged 7-14 years in myopia prevention and control clinic.METHODS:A total of 222 children aged 7-14 years in myopia prevention and control clinic from December 2021 to February 2022 were included. General data of included children were collected, assessing the prevalence of dry eye by the ocular surface disease index(OSDI)scale and Keratograph 5M, and analyzing risk factors for dry eye occurrence by Logistic regression model.RESULTS:The prevalence of dry eye in children in myopia prevention and control clinic was 27.9%. Logistic Regression analysis showed that, allergic conjunctivitis(OR=2.31, 95%CI=1.12-4.78, P=0.02), refractive error(OR=5.57, 95%CI=2.40-12.94, P2h per day(OR=2.74, 95%CI=1.11-6.78, P=0.03), time of playing games >2h per day(OR=2.33, 95%CI=1.12-4.84, P=0.02), outdoor activity time ≤2h per day(OR=4.28, 95%CI=2.02-9.07, P
