The importance of the height standard of student desks and chairs.

The height of student desks and chairs does not meet the standard, which has become a major factor in the current increase in the incidence of myopia among students. According to data surveys, most of the desks and chairs used by lower grade students do not meet the national measurement standards for desks and chairs.

According to the national standard for desk and chair hygiene issued by the Ministry of Health, 9 types of students of different heights have been identified, and the corresponding height standards should be met when using desks and chairs.

For example, if the height of a student is between 143 and 157 cm, the height of the desk used should be 67 cm, the height of the space under the table should be 55 cm, and the height of the chair surface should be 38 cm.

In addition, the regulations also state that although the styles of desks and chairs used in primary and secondary schools can be selected, they must meet the requirements of national standards. But in reality, most desks and chairs do not meet the standards for students. In the survey, a school equipped first-year freshmen with desks that were 67.5 cm high, the empty space under the table was 46.5 cm high, and the chairs were 34.5 cm high. This combination of desks and chairs has high desks and low chairs, which can easily cause primary school students to have insufficient eye distance, and may cause students to suffer from myopia due to close eye use.
