Análisis de la transmisibilidad de la luz en lentes con tratamiento de protección contra luz azul y antirreflejo verde de distintos materiales ofertados en Bucaramanga en el año 2025

Abstract

Exposure to high energy blue light (HEV) from electronic devices and artificial sources has increased, generating risks such as eye fatigue, sleep disturbances and macular pathologies. In Colombia, and specifically in Bucaramanga, it is necessary to evaluate the efficacy, the transmittance of ophthalmic lenses with blue light protection coatings, the improvement of light refraction by ABBE number in thin materials where the use of green anti-reflection improves visual quality in chromatic dispersions and quality of light transmittance. Objective of this study is to analyze the light transmittance in ophthalmic lenses with these blue light protection filters and green anti-reflective coatings, using different materials available in Bucaramanga in the year 2025. Methodology for the study of these coatings It was necessary to evaluate the transmissibility behavior in 18 lenses with blue light filters, 18 lenses with green anti-reflective filters, and 6 lenses without any type of treatment. This behavior was evaluated in different materials by measuring wavelength using a UV-VIS spectrophotometer, an electronic device used to collect practical data on the transmissibility of light wave spectra. In addition, the effect of various weather conditions on blue light protection treatments was analyzed. Results This study showed that the transmissibility of turquoise blue light remains high in practically all samples with a blue filter. On the other hand, in violet blue light, the transmissibility of the lenses was considerably lower, confirming their blocking function. In contrast, in green anti-reflective lenses, transmissibility is generally higher in both turquoise and violet light. This study contributed to decision-making in visual health care in local optometry and to the promotion of information on protective filter coatings. Conclusion Both coatings remained stable over time, and the differences observed can be attributed to variations characteristic of each coating and manufacturer.
