Term ID: 200018
Name: Protanomaly
Synonym: Colorblindness, partial, protan series; Red-weak
Definition: A type of anomalous trichromacy associated with defective long-wavelength-sensitive (L) cones, causing the sensitivity spectrum to be shifted toward medium wavelengths. This leads to difficulties especially in distinguishing red and green.
