The International Myopia Institute introduced the concept of "pre-myopia" in 2019, defining it as children with refractive error ≤+0.75 D and >-0.50 D. By considering baseline refractive error, age, and other quantifiable risk factors, there is a significant likelihood that individuals falling into this category may develop myopia in the future. Therefore, it is deemed worthwhile to implement preventative intervention measures.This article delves into the epidemiology of premyopia in children and adolescents, the criteria for determining pre-myopia, the characteristics of refractive changes, and the existing evidence gaps in pre-myopia control technology. Furthermore, it explores the role and advantages of implementing pre-myopia control to enhance efforts in preventing and managing myopia. The paper highlights the essential value and future trajectory of pre-myopia control in the comprehensive management of myopia. The ultimate goal is to foster collaboration with professionals, aiming to discuss innovative strategies for effectively preventing and managing the onset and progression of myopia.
国际近视眼研究院在2019年提出了“近视眼前期”的概念，将其定义为儿童眼屈光度数≤+0.75 D且>-0.50 D，结合基线屈光度数、年龄和其他可量化危险因素，有较大可能在未来发展为近视眼，故值得采取预防性干预措施。本文从近视眼前期在儿童青少年中的流行病学特征、近视眼前期的判断标准和屈光变化特点、针对近视眼前期防控技术已有的和尚缺的研究证据、开展近视眼前期防控对促进近视眼防控关口前移的作用与收益4个方面，阐述儿童近视眼前期防控在近视眼综合防治中的重要价值和未来方向，以期和专业同道共同探讨有效防控近视眼发生发展的新策略。.
