dc.description.abstractObjective: To compare the effect of the new sunglasses with certification of retinal safety (RSC) and the traditional sunglasses on visual function. Materials and methods: Thirty-six (36) people were assessed (44 ± 14 years) by means of binocular assessment and the usual optical compensation. The sunglasses were characterized by means of the Humphrey spectrophotometer (Zeiss). The main difference between the new RSC sunglasses and traditional sunglasses is in the selective absorbance of short wavelengths, which reduces attenuation of the other bands to achieve a better sight and which maintains the protective effect. The visual function aspects assessed were logMAR visual acuity (VA), stereoacuity (SA), color perception and contrast sensitivity function (CSF). Results: The logMAR VA and SA values with the RSC solar filter are similar to those obtained without the filter; however, with the traditional sun filter, both variables decrease significantly. Color discrimination decreases with both filters, which is a far superior loss with the traditional filter (45 %) compared to the RSC filter (5%). Conclusions: Due to the high level of light exposure, it is essential to protect the sight through solar optical filters; for this purpose, lenses that provide comfort, good visibility and protection for ocular tissues are necessary. Accordingly, a new optical filter has been designed and developed, which improves visibility and comfort while maintaining sun protection, and at the same time optimizes VA, SA and CSF and maintains color perception.spa
dc.description.abstractObjetivo: comparar el efecto sobre la función visual de los nuevos lentes solares con certificado de seguridad retiniana (CSR) y los lentes solares tradicionales. Material y métodos: fueron valoradas 36 personas (44 ± 14 años) de forma binocular y con la compensación óptica habitual. La diferencia fundamental entre los nuevos lentes CSR y los lentes solares tradicionales estriba en la absorbancia selectiva de las longitudes de onda corta. Los aspectos de la función visual evaluados fueron la agudeza visual logMAR (AV), la estereoagudeza (EA), la percepción del color y la función de sensibilidad al contraste (FSC). Resultados: los valores de AV logMAR y de EA con el filtro solar CSR son similares a los obtenidos sin filtro; sin embargo, con el filtro solar tradicional, ambas variables disminuyen significativamente. La discriminación del color disminuye con ambos filtros, pérdida que es muy superior con el filtro tradicional (45 %) en comparación con el filtro CSR (5 %). El filtro tradicional produce una drástica disminución de la FSC para todas las frecuencias espaciales en comparación con el nuevo filtro CSR. Conclusiones: en la actualidad resulta imprescindible proteger el sistema visual mediante filtros ópticos solares; por ello, se ha diseñado y desarrollado un nuevo filtro óptico que, manteniendo la protección solar, mejora la visibilidad y el confort, a la vez que optimiza la AV, la EA y la FSC y mantiene la percepción del color.spa
