Improved method for modeling discrete segment surfaces in myopia control lens design

With increasing awareness of myopia control, various preventive methods have been developed. In recent decades, a range of specialized spectacle lenses utilizing optical interventions has been manufactured and widely adopted for myopia management. However, the underlying optical mechanisms of these lenses remain unclear, and there is a lack of simulation methods for pre-manufacturing analysis. Meanwhile, the structures of these lenses are becoming increasingly complex, even incorporating an aspheric segment array on a curved base. To address these challenges, we have developed an efficient, accurate, and flexible modeling method for simulating such lenses, along with an experimental setup for validation. We provide deeper insights into the optical mechanisms of these lenses and establish a convenient design framework that facilitates the development of optimized lens structures.
