Application of Multiple Segments of Spectacle Lenses for Effective Myopia Control in Adolescent: A Study in Chongqing Population, China

Abstract

Myopia is now a major public health issue in parts of East and Southeast Asia, including mainland China. In this region, around 80% of students completing 12 years of school education are now myopic, and from 10% to 20% have high myopia in excess of −6D (Morgan, I. G. & Jan, C. L. ,2022). The rapid growth of axial length and spherical equivalent refraction (SER) has become one of the most concerning issues for optometrists, patients, and parents of children.It is very important to reduce the burden of myopia through the axial axis(Lam CS. et al., 2022). It can prevent the onset of myopia and slow down its progression, thereby avoiding becoming highly myopic and causing irreversible visual impairment and blindness(Németh, J. et.al., 2021).Multiple segment (MS) spectacle lenses help in controlling myopia and axial growth(Radhakrishnan, H.et al., 2023)
