Abstract:
Objective To investigate and analyze the changes in visual acuity,refractive condition and related influencing factors among the teenager aviation school students in order to ensure the effectiveness of vision surveillance.Methods Four hundred and three students of teenager aviation schools were selected as subjects.The data of their visual changes and refractive condition during the school selection examination and three months after the examination was compared and investigated by questionnaires.The statistics were processed using Wilcoxon's sign rank test and Logistic regression analysis.Results The visual acuity changes were significant (P ＜ 0.05) after only three months at school.The hypopsia rate was 28.79％,and the vision of 9.68％ of the students dropped below 0.8.After mydriasis,the results showed that 27.05％ of the students had refractive errors.Reading posture and food preferences were the two important factors that influenced the visual acuity of the students with short-term vision loss.Conclusion It is important to monitor the vision and refraction regularly to reduce the waste of resources,optimize the selection of potential pilots and develop visual protection measures.Continuous protection,and good visual habits will really help to protect students' vision.
