  • Title: Does the ANSI Z80.3 nonprescription sunglass and fashion eyewear standard go far enough?
    Author: Barker FM.
    Journal: Optom Vis Sci; 1990 Jun; 67(6):431-4. PubMed ID: 2381685.
    Abstract:
    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.
