Relationship between visual fatigue,emotion and sleep quality in military personnel engaged in computer work
Objective To investigate the degree of visual fatigue and its relationship with emotions and sleep quality in military personnel who have been engaged in computer work for a long time,provide theoretical basis for promoting eye health and improving protection against visual fatigue in military personnel.Methods From September to December 2022,the eye examinations were conducted on 863 grassroots soldiers who had been engaged in computer work for a long time using cluster random sampling method.The questionnaire investigation was performed by the visual fatigue scale(VFS),self-rating anxiety scale(SAS),self-rating depression scale(SDS),and Pittsburgh sleep quality index(PSQI),and the data were analyzed statistically.Results The visual acuity of soldiers was 0.91±0.21 with glasses,the intraocular pressure was(14.44±3.10)mmHg,the visual fatigue score[M(P25,P75)]was 10.0(6.0,17.0)points,with the detection rate was 44.2％ .The score[M(P25,P75)]of anxiety,depression and PSQI was 37.5(30.00,50.00),38.75(30.00,50.00)and 4.00(2.00,6.00)points,respectively.There were no statistically significant differences in the visual acuity,intraocular pressure,and scores of depression,anxiety and sleep quality among soldiers with different gender,age,and educational background(all P＞0.05),and the difference in the visual fatigue score was statistically significant(P＜0.05).The visual fatigue in soldiers with computer work was positively correlated with anxiety and sleep quality index(r=0.189-0.359,all P＜0.01),and negatively correlated with vision(r=-0.77,P＜0.05).There was statistically significant differences in the anxiety level and PSQI among soldiers with different visual fatigue(all P＜0.01).The anxiety and sleep quality had a certain impact on visual fatigue,and anxiety had a mediating effect between sleep quality and visual fatigue,with the effect value of 4.5％ .Conclusion The visual fatigue of military personnel engaging in computer work for a long time is closely related to anxiety and sleep quality,and actively alleviating anxiety and improving sleep quality have positive significance in helping soldiers improve visual fatigue in special job positions.
