Monitoring effect of smart glasses on visual behavior in school-age children: analysis of 46 cases

Objective To explore the value of smart glasses in monitoring the visual behavior of school-age children. Methods A total of 46 myopic children aged 9 to 11 years who visited our hospital during April to August 2019 were included in this study. Questionnaires were used to record the participants' daily outdoor time, near-work time, and parental supervision to obtain the baseline value of children's visual behavior. Besides, Akeso smart glasses were used to objectively record the daily wearing time, outdoor time, and near-work time of all participants from September 2019 to December 2019. Subsequently, we compared the differences in the children's visual behavior recorded by the questionnaire and Akeso smart glasses. In addition, we also compared the differences in the children's visual behavior on school days and weekends recorded by Akeso smart glasses, and analyzed the impact of parental supervision on the length of time the child wears glasses. Results The number of children corresponding to the different outdoor time recorded by the questionnaire was as follows: ≤30 min (n=5), >30 to 60 min (n=6), >60 to 120 min (n=23), >120 min (n=12), and this children's visual behavior parameter recorded by Akeso smart glasses was ≤30 min (n=16), >30 to 60 min (n=26), >60 to 120 min (n=4), >120 min (n=0). There were statistical differences between the results recorded by the above methods (P < 0.001). The results of Akeso smart glasses also showed significant differences were in the outdoor time spent on school days and weekends [24 (4, 56) vs 15 (3, 43) min/d, P < 0.001], and in the near-work time spent on school days and weekends (363.36±98.55 vs 329.08±105.90 min/d, P < 0.001). The children with parental supervision wore glasses for 711.80±101.63 min every day, while the wearing time for those without was 641.64±84.79 min, and there were statistical differences between these 2 groups (P=0.026). Conclusion Akeso smart glasses is able to objectively record children's visual behavior and can be used to supplement or replace questionnaires in the prevention and control myopia research.
