Abstract

The filtering of overlapping spectral regions may be used to increase the observer’s gamut in some cases. Therefore, metasurface-based contact lenses (M-CL) may improve the color coding for specific stimuli and deuteranomaly conditions. Here, we address the concerns made by Huertas et al. [Opt. Lett. 45, 5117 (2020) [CrossRef]  ], regarding the color perception improvement obtained by color filters, in general, and specifically by our M-CL, in case of deuteranomaly.
