本文件适用于所有名义上的afocal（plano power）太阳镜，用于在跑步、骑自行车和进行类似的积极生活方式娱乐活动时，防止太阳辐射、风、灰尘和雨水等环境因素，但不适用于要求增强抗冲击性的竞技体育活动。 本文件规定了其他材料、设计、性能和标记要求。ISO？中给出了其他适用要求12312？1. 这种类型的太阳镜旨在减少事故中对佩戴者的二次危害，而不是提供大量的冲击保护，这在眼镜形式中可能很难实现。 本文件不适用于: a） 防人工光源辐射的护目镜，如用于日光浴的护目镜； b） 用于特定运动的护目镜，如滑雪护目镜或其他类型——见ISO18527（所有部分）； c） 运动护目镜，包括使用球、棍子、球棒、球拍或其他工具； d） 医学上规定用于减弱太阳辐射的太阳镜； e） 用于直接观察太阳的产品，如用于观看日偏食或日环食，ISO12312-2适用； f） 用于职业眼睛保护的产品–例如，请参阅ISO16321（所有部分）。

This document is applicable to all nominally afocal (plano power) sunglasses for protection against environmental elements, such as solar radiation, wind, dust and rain when running, cycling and following similar active lifestyle recreational activities but not intended for competitive sporting activities where enhanced impact resistance is required. The document specifies additional material, design, performance and marking requirements. The other applicable requirements are given in ISO？12312？1. This type of sunglass is designed to reduce secondary hazards to the wearer in an accident rather than to provide high amounts of impact protection which may be difficult in a spectacle format. This document is not applicable to: a) eyewear for protection against radiation from artificial light sources, such as those used in solaria; b) eye protectors intended for specific sports, e.g. ski goggles or other types – see ISO18527 (all parts); c) eye protectors for sports that include the use of a ball, stick, bat, racquet or other implement; d) sunglasses that have been medically prescribed for attenuating solar radiation; e) products intended for direct observation of the sun, such as for viewing a partial or annular solar eclipse, for which ISO12312-2 applies; f) products intended for occupational eye protection – for example, see ISO16321 (all parts).
