Long-term effects of blue-blocking spectacle lenses on color perception Santandreu, María Valero Benito, Eva María Gómez Robledo, Luis Huertas Roa, Rafael Martínez Domingo, Miguel Ángel Hernández Andrés, Javier The use of blue-blocking filters is increasing in spectacle lens users. Despite the low absorption in the blue range, some users complain about these filters because they affect their color perception. In a pilot study we have evaluated how the long-term use of 8 different blue-blocking filters impact the color perception during more than 2 weeks on a group of 18 normal color vision observers, compared with a control group of 10 observers. The evaluation was done using the FM100, the Color Assessment and Diagnosis (CAD) and an achromatic point measurement. Our results show that there is a trend to worsen with the filters on. 2022-06-27T08:23:42Z 2022-06-27T08:23:42Z 2022-05-23 journal article María Santandreu...
