The deterioration of children’s eyesight is on the rise. Children's lives have changed in a short period of time, such as an increase in blue light due to the use of electronic devices. It is necessary to consider non-traditional content of health guidance for prevention. The accurate visual acuity test is important to examine the effects of visual acuity and environmental or living factors. We examined the accuracy of the visual acuity test with the three stage Landolt ring for children from the relationship with the eye axial length.
After performing a normal detailed visual acuity test of the children and the correlation analysis with the eye axial length, we examined the distribution of the eye axis according to the results of the three-stage visual acuity test by the Landolt ring.
The number of children measured eye axial length was 13. The correlation coefficient between detailed visual acuity test and eye axial length was negative. According to the results of the three-stage visual acuity test, the distribution of the eye axis is good for the right eye: the average eye axis of “A” was 23.44 mm, moderate: the average of “B” was 22.58 mm. The average of the left eye axis for “A” children is 23.34 mm, for “B” is 23.08 mm, and for “C” is 23.7 mm.
The correlation coefficient between the detailed visual acuity test and the eye axial length was negative on both sides, namely a negative correlation between the visual acuity and the eye axial length. There was a possibility of not correspondence between the three-stage visual test and the eye axial length. In the case of children, it was considered that their visual performance and answers were different because of their mood and physical condition on the day.
