Summary

This study tests two types of special glasses (DIMS and D2 lenses) to see if they can slow down worsening nearsightedness in children whose vision is getting worse quickly. About 59 children will wear these glasses for 4 years, and researchers will measure changes in their eyesight and eye length every 6 months. The goal is to find a better way to control myopia progression without surgery or daily eye drops.
