The Japan Ophthalmologists Association announced on the 19th (September) that all over the country in the 2010-11 fiscal year 941 people interviewed by ophthalmologists was found to have congenital abnormal color sensation. Among the junior and senior high school students (185 persons) who had declined entering into a school of higher level or an employment, about half of them did not notice their abnormality, and there was also a case which trouble occurred in the course of selecting their future.
The color perception test for schools conducted in the elementary school fourth years was no longer performed after the fiscal year 2003, because of the effect, the society had appealed for the need to carry on with the inspection.
According to the results of an investigation, among the junior and senior high school students in the generation who became a fourth grader in an elementary school after the 2003 fiscal year who were not entering into a school of higher grade or an employment, 45% or 85 people did not notice the abnormality.
As for congenital abnormal color sensation, one person in 20 men and one in 500 women could be found. Because of the abnormalities of the cell which detected the color, there was the obstacle of being difficult to distinguish between red and green. Although the inspection had once been conducted at the elementary school, after the 2003 fiscal year, for reasons that it might lead to discrimination, it was deleted from the indispensable items on the school health laws, and the inspection became an arbitrary enforcement item.
Health checking is always useful for the young so as to find out health troubles in an early stage.
