Photolithography Microstructure Myopia Management Lenses in Preventing and Controlling Myopia in Children and Adolescents
Enrolling by invitation · Not applicable
Conditions studied: Myopia, Child Myopia Progression
In brief
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.
