Clinical Trial: Clinical Study on the Effectiveness of Diverse Segments Defocus Optimization in Spectacle Lenses for Slowing Myopia Progression

U.S., Jan. 8 -- ClinicalTrials.gov registry received information related to the study (NCT07323251) titled 'Clinical Study on the Effectiveness of Diverse Segments Defocus Optimization in Spectacle Lenses for Slowing Myopia Progression' on Sept. 13, 2025.

Brief Summary: Clinical Trial

The goal of this clinical trial is to evaluate the effectiveness of two types of Diverse Segments Defocus Optimization (D.S.D.O.) spectacle lenses in slowing myopia progression in children. It will also assess the safety of these lenses. The main questions it aims to answer are:

Do D.S.D.O. lenses reduce the progression of myopia as measured by changes in cycloplegic refraction and axial length? What adverse events do participants experience when wearing D....
