通过比较与分析16个不同品牌常见类型离焦镜片的相关参数，思考近视防控离焦镜片的未来发展。调研了16个不同品牌近视防控离焦镜片的相关参数，结合相关文献分析各离焦镜片离焦理论设计与研发，发现各品牌离焦镜片的具体光学设计原理、外观等各异，镜片相关参数具有差异性。为了规范离焦镜片在近视防控领域的应用，需要国家出台离焦镜片相关设计、制造和质量检测标准，发布验配、装配规范、镜片应用效果评估等规范。

Compared and analyzed the parameters of common types of 16 different brands of defocus lenses, the future development of prevention and control of myopia defocus lenses was considered. The parameters of 16 different brands of defocus lenses for myopia controlling were investigated, and the defocus lenses were designed and developed according to various types of defocus methods, but the specific optical design principle, appearance and other differences, the relevant parameters of lenses had differences. To standardize the application of defocus lenses in the field of myopia prevention and control, the country needs to issue the relevant design standards, manufacturing standards, quality inspection standards, fitting, assembly standards, lens application evaluation standards and other documents.
