Abstract

Current UV protection regulations mainly center on sunglass lenses’ light passage, using quantitative criteria based on sunglass categories. Yet, studies, including this one, stress the necessity to enhance and adjust these norms. Our findings underscore aligning standards, notably the Brazilian ISO NBR 12312-1, with ICNIRP guidelines. Environmental radiation dispersion where sunglasses are worn can impact eye safety despite dark lenses, potentially harming protection due to pupil dilation. This project marks a pivotal step in UV protection analysis, crafting a methodology to measure light entering the eyes as UV rays penetrate sunglass lenses. We devised an apparatus with LEDs, sensors, and a mannequin to gauge eye-reaching radiation. Preliminary results reveal 10 to 15% of this wavelength’s light penetrates the eyes, varying based on lens characteristics like material and curvature. However, these initial tests only validated the system with red LEDs, limiting their scope. Validating this research urges adapting existing norms to assess UV radiation reaching the eyes and establish effective protection methods.
