Summary

This study tests two types of special glasses (D.S.D.O. lenses) designed to slow the progression of nearsightedness (myopia) in children aged 6 to 14. About 120 children will wear the glasses daily for one year and have regular eye checkups. The goal is to see if these lenses can reduce how fast their eyesight gets worse, and to check for any side effects.
