近视眼是影响我国儿童青少年眼健康的焦点问题。远视储备是眼球发生近视前的屈光状态，是眼轴长度与角膜及晶状体等参数之间动态匹配的结果，对于近视眼防控意义重大。我国一直缺乏儿童眼球发育参数的指导依据以及遗传因素影响的参考资料，尤其针对上述参数在儿童眼球正视化过程中变化规律的总结。为了促进儿童青少年近视眼防控工作的标准化，规范人群筛查和临床治疗，使社会各界对近视眼的预防干预和评价有据可依，中华预防医学会公共卫生眼科分会基于我国不同地区儿童青少年的屈光不正调查数据，针对我国学龄儿童正视眼在不同年龄段眼球远视储备、眼轴长度和角膜曲率的参考区间及相关遗传因素达成共识性意见。

Myopia is a focal issue affecting the eye health of children and adolescents in China. Hyperopia reserve is the refractive state before the occurrence of myopia. As the result of dynamic matching between the axial length, cornea and lens, it is of great significance to the prevention and control of myopia. There has been a lack of the reference basis for children′s eyeball development parameters and the influence of genetic factors, especially the changing law of the above-mentioned parameters in the process of children′s "emmetropization". To promote the prevention and control of myopia in children and adolescents and to standardize population screening and clinical treatment, based on the survey data of refractive errors in children and adolescents from different regions, a consensus has been reached on the reference interval of hyperopia reserve, axial length and corneal curvature and related genetic factors of emmetropia at different ages among school-age children by the Public Health Ophthalmology Branch of the Chinese Preventive Medicine Association.
