Effect of Wavelength-Controlled Lenses on Response Time to Visual Stimuli Presented on a Screen

Abstract

The effect of wavelength-control lenses on visual reaction time to on-screen visual stimuli was investigated. Ten healthy participants were examined using the ColorDx® CCT-HD™ system (KONAN MEDICAL) under two conditions: refractive correction lenses and wavelength-control lenses. Visual reaction time was measured for two optotype sizes. No significant difference was observed between the two conditions for the logMAR 1.2 optotype (equivalent to a decimal visual acuity of 0.06). In contrast, for the logMAR 0.4 optotype (equivalent to a decimal visual acuity of 0.4), visual reaction time was significantly shorter under the wavelength-control lens condition. These findings suggest that wavelength control may enhance the efficiency of visual information processing for on-screen stimuli, indicating potential applications for improving visual input in digital environments and gaming scenarios.
