Study Status: Completed

Recruit Status: RECRUITING

Condition: Myopia, Progressive

Study Type: INTERVENTIONAL


Official Title: A Randomized Controlled Study on the Effectiveness, Safety and Adaptability of Double Helix Design Defocus Lens Spectacle Frames for Correction of Visual Acuity in Children and Adolescents, and Contro

Brief Summary: This study uses 1.585 double helix defocus lens PC lenses with a unique optical design that includes a globally coherent visible area and complementary left and right helices that can form clear images.In addition, the helical arrangement and reduced slit area can generate defocusing signals, inhibiting the development of myopia.Therefore, based on previous research, this study plans to evaluate the safety and effectiveness of 1.585 double helix defocus lens PC frame eyeglasses in controlling the progression of…
