AIM:To observe the effect of wearing glasses with full correction or under-correction on the development of juvenile myopia.

METHODS:This study included 132 cases(264 eyes )from January 2008 to September 2012 who were collected from our clinic.They were divided into 2 groups, full correction and under-correction. Students in group 1 wore glasses with full correction, students in group 2 wore glasses with under-correction 0.25D to 0.5D lower than normal. Reexamination was done every 6mo.After 12mo, refractions were checked, the development of myopia was compared.

RESULTS:There were no statistically significant differences between two groups after 6mo(P=0.0693); however, there were significant differences after 12mo(P=0.0013).

CONCLUSION:The development of myopia is slow if students often wear glasses with full correction.
