abstract
The negative effect of visual acuity for growing children led by widely use of IC device such as mobile phone is concerned today. Heavy use of electronic device such as PC in early age will bring poor visual acuity, and an inconvenience in exercise caused by wearing glasses. In this study, we used wearable devise to search relations between daily lives of children and a decrease in vision in add to a preexisting questionnaire. Compared with the duration of watching TV and reading books of PVA( Poor visual acuity) and NPVA(Non poor visual acuity), PVA students were turned out to be using more time in doing, which supports previous studies. The relevance to visual acuity and sleep was clarified to be significantly shorter in NPVA in terms of nocturnal awakening, and also the average of a sleep and a deep sleep duration were longer in NPVA. No significant difference was observed due to the small parameter. From now on, the further work is needed to examine child's sleep conscientiously, including enriching health guidance for sight maintenance.
