These days, the time when children go to bed is becoming later than before. In addition they spend too much of their time in playing video games and portable games and watching TV. This tendency was expected to have been the reason that the number of children poor is increasing. In the previous paper, "The Relation between Bedtime and Poor Eyesight (1)", the relation between children's bedtime and their eyesight was examined. This time, we analyzed the reasons why many children go to bed so late; what they are doing until late at night. The main reason was revealed to be watching TV. On weekdays, the children who go to bed late at night watch TV for longer times on average than those who don't. On weekends, the same tendency was shown, excluding the children who go to bed before nine. According to the earlies paper, the ratio of children with poor eyesight was low among the children who go to bed before nine. At least, if children go to bed before nine, the time during which their eyes are strained by artificial light decreases. So, we can say that the time children watch TV should be cut down in order to avoid the deterioration of their eyesight.
