A person who suffers from protanopia

Question

Quizplus · Accepted Answer

Protanopia is a type of color blindness that results in the absence or malfunction of the L-cones in the retina, which are responsible for detecting long-wavelength light (red). Therefore, a person with protanopia lacks only L-cones, while they still have M-cones (for medium-wavelength light, green) and S-cones (for short-wavelength light, blue-violet). This means that they are not monochromats (people with only one type of cone) but rather dichromats (people with two types of cones).
