We tend to overtax our eyes. It is because we daily watch TV, use PC, play video games and write e-mails on cell phones these days. When we continue using our eyes for hours, the ciliary muscles become abnormally tensed. As a result, we risk developing accommodative asthenopia. We can prevent the accommodative function decline by using a training stick to alternately focos on distal and proximal targets. We conducted training to reduce eye strain for about two months at an elementary school, among children in the first, third, and sixth grades. The sixth grade children did the training for only five weeks, because they had to participate in school events. We checked their near visual acuity before and after the training period in order to validate the evidence of the training. Then, we classified the children of each grade into two groups: children whose near visual acuity is more than 0.8 and children whose near visual acuity is less than 0.8. We analyzed the change of their near visual acuity. According to the analysis, for the first and the third grade children, the under 0.8 group progressed significantly. On the other hand, there was little progress seen in the 0.8 group. The sixth-grade children progressed little in either group. The result suggests an improvement in near visual acuity in the first and the third grade children. We are planning to validate the evidence of the effect of grade and of the training period.
