In recent years, many products that cut blue light, including eyeglasses, have been put on the market. Blue light refers to blue light with a wavelength of 380 nm to 495 nm. Since the peak sensitivity of human S-cones is around 440 nm, cutting blue light may affect color discrimination. In this study, we investigated the effect of blue light-cut lenses on human color discrimination characteristics. Previous studies showed that subjects' ability to discriminate the taste of purple was reduced and that subjects' discrimination ability was better or worse. The purpose of this study was to test hypotheses regarding the cause of the subjects' reduced discriminative ability.
