Myopia of children: The length to the back of the eyes is about the same as that of adults.
Myopia is a disease which makes it difficult to see distant objects, and is related to the length of the ”eye axis” from the surface of the eye to the retina at the back.
The country ( Japan ) first examined the eye axes of elementary and junior high school students.
If the axis of the eye to the retina, where you can feel the brightness, color, and shape, is getting longer and longer, myopia is progressing.
The average length of the eye axis is about 24 mm for adults.
In the sixth grade of elementary school, the average was 24.22 mm for boys and 23.75 mm for girls.
It was about the same as an adult.
In the third year of junior high school, boys were 24.61 mm and girls were 24.18 mm, which were longer.
When they examined the eyes, about 20% of the first graders had lower eyesight than 1.0 when they didn’t wear glasses.
The number of third-year junior high school students increased to about 60%
