福建省城市小学生视力不良率的动态分析

应用可比性原则,将2000年与1990年及1995年福建省城市小学生的视力不良率进行纵向对比,结果发现,福建省城市小学生的视力不良率一直居高不下.造成这种现象的原因是学习任务繁重导致长时间、近距离用眼过度、班生数太多、课桌椅高差与学生坐高不符及每周体育锻炼不足等.对此,学校、家长应引起高度的重视.

Development Analysis on the Proportion of Poor Vision of the City Pupils in Fujian Province

Using the principle of comparability ,I make a vertical comparison on the proportion of the city pupils whose visions are poor in Fujian between 2000 and 1990, 2000 and 1995.Then I draw a conclusion :the proportion of poor vision of the city pupils in Fujian is always high. there are a lot of reasons. In order to study hard, the pupils use eyes for a long time, and use them too closely; the population of a class is too large; the height of desks and chairs are unmatched with the height of the pupils; there aren't enough physical exercises for the pupils every week. Therefore, the schools and the parents must pay more attention to it.
