This study checks how well a new type of glasses helps control myopia (nearsightedness) in children aged 6-8. **Myopia** means seeing near things clearly, but far away things are blurry. The study lasts for 24 months (2 years), and children will not wear contact lenses during this time. It is a **randomized, controlled** study, meaning participants are randomly assigned to different groups to compare results. The study is also **masked**, so neither the children nor the observers know which group they are in, to ensure unbiased results.

Children who join the study will need to wear glasses for at least 10 hours a day, except during activities like swimming or sleeping. They will have regular eye checks to see how their vision changes over time.

• **Study Duration**: 24 months (2 years)
• **Visits Needed**: Regular eye check-ups
• **Risks**: No known risks, but must not wear contact lenses
