Abstract:
Studies on 5,050 pupils at 3 levels of primary education in Ha Noi, Nam Dinh and Thai Nguyen during 1999-2001 showed that: the myopia of pupils had increased by the learning grade. The myopia rate of pupils in urban areas is higher than that in suburb areas. Some factors were related closely to the rate of myopia including the lighting level inside classes, the dimensions of tables and desks, the sitting position of pupils in classes
