Comparing defocus-enhanced and single vision spectacles for myopia control in children

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effectiveness of vision function training using defocus-enhanced spectacles compared to single vision spectacles in managing myopia progression in children aged 6 to 18 years. Participants will undergo vision function training while wearing either type of spectacles to determine which is more effective in controlling myopia. The study will include children diagnosed with myopia within specific refractive error ranges and will exclude those with certain eye diseases or genetic syndromes. The goal is to provide insights into better management strategies for myopia in the pediatric population.
