Evaluate the effectiveness of different lithographic microstructured myopia management lenses in controlling the progression of myopia in children and adolescents, as well as the safety and comfort of wearing them. Explore effective defocus microlens designs for myopia control and the feasibility of applying lithographic microstructured myopia management lenses in myopia prevention and control.
