近年来，近视的发病率逐年升高，人群基数逐年庞大，并逐渐成为我国乃至世界范围内的一个重大公共卫生问题。近视人群眼轴变长，可继发一系列结构和功能变化，提高相关眼病的发生概率，甚至致盲。近视一旦出现，就不能逆转，只有选择合适的治疗方案，才能进一步控制近视的发生发展，减少出现眼部并发症的概率。目前，离焦理论是近视防控的一大热点，文章通过系统性回顾相关文献，阐述了离焦相关原理，总结了多区正向离焦镜片(DIMS)的相关研究结果，分析DIMS相较于当前已有的近视防控手段的优点与不足，探讨了以DIMS为代表的离焦镜片的应用前景及方向，以期为儿童青少年的近视防控提供参考依据和指导。

[Abstract]
In recent years, the incidence of myopia has been increasing alongside the growing global population, emerging as a significant public health challenge worldwide. Individuals with myopia exhibit an elongated axial length, which leads to various structural and functional ocular changes, resulting in the risk of related eye diseases and, in severe cases, blindness. Unfortunately, once myopia develops, it is irreversible. The only way to prevent or slow its progression is through appropriate treatment. The current focal point in myopia prevention and control is the peripheral myopic defocus theory. This paper summarizes the relevant research on defocus incorporated multiple segments(DIMS)lenses, following a systematic analysis of the literature. It analyzes the advantages and disadvantages of DIMS compared to other myopia control methods, and discusses the application prospects and future directions of defocus lenses represented by DIMS, aiming to provide reference and guidance for the control of myopia progression in children and adolescents.
