Protanopia is the condition where there is a lack of L-cones (long-wavelength sensitive cones), leading to difficulties in distinguishing between red and green colors. Deuteranopia is the condition where there is a lack of M-cones (medium-wavelength sensitive cones), also resulting in red-green color vision deficiency.
