Metasurface-based contact lenses for color vision deficiency: comment

Recently Karepov and Ellenbogen [ Opt. Lett. 45 , 1379 ( 2020 ) OPLEDP 0146-9592 10.1364/OL.384970 ] claimed that a new metasurface-based contact lens is able to correct deuteranomaly. Unfortunately, their results are not supported by psychophysical experiments, and some key assumptions in their sim...

Description
Summary:Recently Karepov and Ellenbogen [ Opt. Lett. 45 , 1379 ( 2020 ) OPLEDP 0146-9592 10.1364/OL.384970 ] claimed that a new metasurface-based contact lens is able to correct deuteranomaly. Unfortunately, their results are not supported by psychophysical experiments, and some key assumptions in their simulations were misinterpreted. All of this has led to wrong conclusions providing false expectations to the color vision deficiency community.
