No results posted yet for this study

Summary

The purpose of this study is to evaluate the effect of +3.00ADD vs single vision spectacle on the progression of myopia in children. Many studies applying bifocals or multifocal spectacles to intervene the progression have been carried out based on the idea that myopia was caused by excessive accommodation, however, the effect was limited. The possible reason is that bifocal or multifocal spectacles still not fully adjust the accommodative error in myopia children.
