Dichromacy characterized by a lowered sensitivity to green light resulting in an inability to distinguish green and purplish-red
Color blindness or color vision deficiency is the inability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or exposure to certain chemicals. ...
A form of color blindness. Involves a defect in distinguishing between red and green
One of the two varieties of red-green color blindness (also known as green-dichromacy). Deuteranopia results from the loss of function of the M-cones. Deuteranopes, in contrast to protanopes (see protanopia), display essentially normal visual sensitivity throughout the spectrum.
