Analysis on subjective symptoms and influencing factors of visual fatigue among college students
Objective To investigate the subjective symptoms and influencing factors of visual fatigue among college students,so as to provide a basis for preventing visual fatigue among college students.Methods In November 2022,a survey was conducted on 1 332 college students from Jinzhou Medical University to investigate their eye use behavior;Vis-ual fatigue was investigated by Conlon Visual Inappropriate Scale and Convergence Insufficiency Symptom Scale(CISS)respectively.The influencing factors of visual fatigue were statistically analysed using univariate and multivariate logistic regression analysis.Results Of the 1 332 university students,627(47.07％)had low myopia(myopia＜3.00 D),875(65.69％)had neither parent with myopia,and 200(15.02％)had definite dry eye.Smoking in the past 2 weeks:1 103 individuals who never smoked(82.81％).Drinking in the past 2 weeks:978 individuals who never drank(73.42％).There were 203 college students diagnosed with visual fatigue through the Conlon Visual Insufficiency Scale survey,with an incidence of 17.93％.Subjective symptoms and factors related to visual fatigue were associated with the presence of myopia,dry eyes,abnormal regulatory function,oth-er chronic ocular surface abnormalities,smoking in the past 2 weeks,and average daily close work hours(x2=20.854 9,49.978 9,75.666 6,111.146 7,10.892 9,12.624 3,respective-ly;P＜0.05)Multivariate logistic regression analysis showed that abnormal regulatory function,myopia,other chronic ocular surface abnormalities,and smoking in the past 2 weeks were the main risk factors for visual fatigue(OR=0.342,0.407,2.482,respectively).A total of 308 college students were diagnosed with visual fatigue through CISS survey,with an incidence of 27.20％.The factors associated with subjective symptoms and visual fatigue were whether myopia,dry eyes,other chronic ocular surface abnormalities,abnormal regulation function,eye movement function,other eye factors that may cause visual fatigue,as well as alcohol consumption in the past 2 weeks,and the time spent using electronic prod-ucts at close range every day(x2=43.646 4,73.053 5,89.465 1,110.839 6,61.812 2,106.537 5,8.261 8,respective-ly;P＜0.05).Multivariate logistic regression analysis showed that abnormal regulatory function,myopia,dry eyes,and the presence of other eye factors that may cause visual fatigue were the main risk factors for visual fatigue(OR=0.529,0.316,0.559,1.474,respectively).Conclusion Visual fatigue can seriously affect the learning and life of college students.Abnormal regulatory function,myopia,dry eyes,and the presence of other eye factors that may cause visual fa-tigue are the main risk factors for visual fatigue.
