Root Explanation

Deuteranopia is formed from "deutero-" (from Greek "deuteros", meaning second) and "anopia" (from Greek "anopsia", meaning blindness). The term refers to a type of color blindness where the individual has difficulty distinguishing between certain colors, particularly greens and reds, due to the absence of the second type of cone cells in the retina.

Memory Tip

Think of 'second' ('deutero-') and 'blindness' ('anopia') to remember that deuteranopia refers to a condition of being blind to certain colors, particularly the second set of colors in the spectrum.
