The Claim
Macular pigment optical density does not meaningfully correlate with yellow-blue color discrimination thresholds in normal trichromats, indicating that the spectral filtering properties of macular pigment do not significantly alter sensitivity to tritan (blue-yellow) chromatic contrasts.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
The amount of yellow pigment in the center of the human eye does not change how well people with normal color vision distinguish between blue and yellow hues.
See the scientific wording
Macular pigment optical density does not meaningfully correlate with yellow-blue color discrimination thresholds in normal trichromats, indicating that the spectral filtering properties of macular pigment do not significantly alter sensitivity to tritan (blue-yellow) chromatic contrasts.
The yellow pigment in the center of the eye absorbs blue light, but this does not change how well the blue-sensitive cells in the retina detect differences between blue and yellow colors because the signal difference between blue and yellow is determined by how the blue cells compare to the green and red cells, not by how much blue light is blocked.
What the research says
1 studyStudy: Effect of macular pigment optical density on Yellow‐Blue and Red‐Green colour discrimination
The study found that how much yellow pigment is in the center of your eye doesn't change how well you can tell apart blue and yellow colors — your ability to see those colors stays the same no matter how much pigment you have.
