• Significance and Effectiveness of Near Visual Acuity Test in Information-Oriented Society : A Study of Visual Acuity, Refraction and Accommodative Efficiency in Primary School Students

抄録

Visual acuity, refraction and accommodation were tested in 837 primary school students in Chiba Prefecture, in June 2012. The previous study reported correlation between ametropia and far /near visual acuity. The purpose of this study was to show correlation between refractivity, accommodation and far /near visual acuity. The results show that the higher the school grade, the lower the ratio of hyperopia and the higher the ratio of myopia. According to the refraction test results, the higher the school grade, the more myopic is the uncorrected visual field. Additionally, it was found that uncorrected refractivity of 4th graders and above was within the myopic range. The study also investigated whether or not student visual acuity was properly managed in daily life through spectacle wear. The results indicated that 4th graders and above wear corrective glasses. According to the accommodative test results, 50.5% of the students (417 persons) showed normal accommodation. The higher the school grade, the higher the number of adjustment revolutions required. This means that accommodation improves with age. Regarding the relation between far visual acuity and accommodation, the poor far visual acuity group showed less numbers of revolutions for adjustment. It was concluded that accommodative efficiency was correlated with far visual acuity. Similarly, the poor near visual acuity group showed less numbers of revolutions for adjustment. It was concluded that accommodative efficiency was correlated with near visual acuity. It was also confirmed that in approximately half the students, accommodation was in a strained state in daily life. Continued strain can weaken accommodative function, causing difficulty in focusing and leading to poor visual acuity. These test results revealed that many students had visual acuity that "could cause problems with learning."
