This paper reports on the 17-year development of the current Z80.3 Sunglass Standard. The dioptric tolerances of +0.125 to -0.25 D power, 0.125 D astigmatism, 0.25 delta prism, and 0.18 D power imbalance are based on research by optometry's leaders. The traffic signal and luminous transmittance requirements are the result of study of the literature and original research. There has been much misunderstanding regarding the UV transmittance specifications. They too were exhaustively researched and discussed. That work is reviewed in detail. New equations for calculating exposures are presented with sample spectra. Graphic evaluations of severe risk exposures are presented. They show that based on the accepted criteria, for reasonable assumptions the Standard offers a 10x margin of safety. Studies of retinal risk indicate the Standard provides ample protection. Some criteria need further study. Potential problems are based on the fact that some sunglasses are too dark for driving and that use of ordinary sunglasses for sports provides inadequate protection from injuries.
本文报告了现行Z80.3太阳镜标准17年的发展历程。屈光度公差为+0.125至-0.25D、散光0.125D、棱镜度0.25Δ以及屈光参差0.18D是基于验光领域领军人物的研究得出的。交通信号和透光率要求是文献研究和原创研究的结果。关于紫外线透过率规格存在诸多误解。这些也经过了详尽的研究和讨论。文中详细回顾了相关工作。给出了用于计算曝光量的新公式及示例光谱。展示了严重风险曝光的图形评估。结果表明，基于公认标准，在合理假设下该标准提供了10倍的安全裕度。视网膜风险研究表明该标准提供了充分的保护。一些标准还需要进一步研究。潜在问题在于，有些太阳镜颜色过深不适于驾驶，而使用普通太阳镜进行运动提供的防伤害保护不足。
