Influencing factors questionnaire for self content, the Person who referred to the child suPPort collected for statistical analysis.Results:1.The detection rate of Preschoolers vision disorders was12.42%(195/1570), refractive error detection rate was20.19%(317/1570), the total abnormal detection rate of27.58%(433/1570) in Kunshan City.2. The vision abnormalities detected rate of boys was8.40%(88/833), the vision disorders detection rate of girls was10.99%(107/737); There were statistically significant difference between two grouPs (%=5.62, P<0.05).3. There were statistically significant difference between abnormal vision of three classes(x2=93.27,P<0.01);There were statistically significant difference between each class tyPe of vision disorders (x2=97.06,P<0.01); There were statistically significant difference between the detection rate and tyPe of refractive error detection rates hyPeroPia (x2=74.72and81.53, P<0.01).4. There were statistically significant difference vision anomaly detection rate among age grouPs (x2=47.70,P<0.01); There were statistically significant difference between the detection rate of myoPia (x2=98.88,P<0.01); There were statistically significant difference of the refractive anomaly detection rate and refractive error hyPeroPia detection rate among the age grouPs (x2=110.74and137.69, P<0.01).5.The Influencing factors of developmental abnormalities of vision of Preschoolers in Kunshan City was contact the comPuter time and time outdoors; The influencing factors of refractive dysPlasia was maternal age, birth weight, access to comPuters time sleePing Posture whether to turn on the lights, sleeP, sleeP time, foodsoftware and hardware Preferences;The Influencing factors of total abnormal visual development was the age of the mother during Pregnancy medication, whether birth asPhyxia, birth weight, and exPosure to comPuter time, outdoor activities, time, sleeP time, sleeP whether to turn on the lights.Conclusions:1.The abnormal vision of Preschoolers in Kunshan City refractived the abnormal status quo rendered girls high incidence trend of younger age, visual development anomalies can not be underestimated, it is worth about health departments to attach importance.2.
