Children are given visual acuity tests at school. The purpose of the tests is to facilitate school education. There are two types of visual acuity: far-vision and near-vision visual acuity. Far-vision visual acuity is required, for example, when reading something written on a white board in a classroom. On the other hand, near-vision visual acuity is needed when reading textbooks, notebooks, or when looking at computer screens. However, only far-vision visual acuity tests are stipulated in the "School Health Law". As a result, a near-vision visual acuity test is not typically included in medical examinations at public schools. However, we believe that a near-vision visual acuity test is necessary, and so in this paper we analyze some basic data about the relationship between children's near-vision visual acuity and their vision-related behavior. For the purposes of the paper, we examined both far-vision and near-vision visual acuity tests of elementary school children. We found that children whose far-vision visual acuity was under 1.0 had 4 vision-related behavioral problems, and that children whose near-vision visual acuity was under 0.8 had six such problems. Children whose far-vision visual acuity is found to be lacking are given remedial treatment to improve their eyesight. We therefore strongly recommend the addition of near-vision visual acuity tests in public schools so that children found to have near-vision acuity problems can be given treatment too.
