The recent public concern regarding sunglass protection from UV energy has sparked a significant debate among those in the research community and industry. This debate grows out of concern for the known effects of UV energy in producing or contributing to eye effects such as keratitis, cataract formation, and retinal damage. The ANSI Z80.3 Standard addresses itself to this issue by setting levels of UV energy that are permitted to be transmitted in various labeling categories for over-the-counter sunlenses. One important issue is that the ANSI Standard does not provide for an absolute block of UV energy in any category of these lenses. Because the technology to provide this sort of total UV block is currently available, it is argued that there should be at least one category of lens that is fully protective in the UV range.
近期公众对太阳镜防紫外线功能的关注在研究界和行业内引发了一场激烈辩论。这场辩论源于人们对紫外线已知影响的担忧，紫外线会导致或加剧眼部问题，如角膜炎、白内障形成和视网膜损伤。美国国家标准学会（ANSI）Z80.3标准通过设定非处方太阳镜不同标签类别中允许透射的紫外线能量水平来解决这一问题。一个重要问题是，ANSI标准并未规定这些镜片的任何类别要完全阻隔紫外线能量。鉴于目前已有实现这种完全阻隔紫外线的技术，有人认为至少应有一类镜片在紫外线范围内具备完全防护功能。
