Protection against ultraviolet radiation (UV) is essential for human health, as the high incidence of these rays causes harmful effects on the body. Similarly, ocular health relies on the protection provided by sunglasses. However, current regulations governing the manufacturing of these items primarily focus on the lenses’ UV protection, neglecting the impacts of different frame geometries on blocking retro-scattered light from the environment. In response to this, a prototype was developed to measure the protection associated exclusively with the geometries of sunglass frames. This was achieved through a sphere retro-illuminated by red LEDs and controlled by an embedded system. Subsequently, confirmatory results of the raised hypothesis were generated, motivating changes in the system to establish a setup with characteristics more reflective of real-world environments, aiming to simulate ultraviolet light with precision. Subsequently, a LED-sensor ensemble with precise response in the UVA spectrum was implemented, enabling the reading of LED UV intensity through a photodiode generating an electric current. This current is then converted into voltage levels by a transimpedance circuit, with the goal of facilitating future analog-to-digital conversion and processing of results by the system's microcontroller. The developed system presents promising advancements in assessing UV protection offered by sunglasses frames, complementing existing regulations that primarily address lens properties. The integration of precise measurement mechanisms enhances the accuracy of evaluating sunglasses’ overall UV-blocking capabilities, contributing to the enhancement of ocular health protection strategies.
