Counting the number of S cones present on the person's retina is not a method used to assess color deficiencies. S cones are responsible for detecting short-wavelength light (blue-violet), but color deficiencies typically involve issues with the M cones (responsible for medium-wavelength light, or green) or L cones (responsible for long-wavelength light, or red). Methods A, C, and D are commonly used to assess color deficiencies.
