Deuteranopia

Most common form of color blindness, involving confusion of red and green color hues.

This is a specific type of color blindness that involves confusing red, green, and sometimes yellow color hues. This is the most common type of color blindness.

How Deuteranopia Impacts Vision

Those who experience this type of color blindness can make out the general color scheme of reds and greens, but with a distortion of what they actually look like. Someone with deuteranopia can distinguish two or three different hues of green, versus seven different shades for someone with normal vision.

Deuteranopia Causes

Deuteranopia is 10 times more likely to occur in males than females. This is because color blindness is a sex-linked trait attached to X chromosomes. Females have two X chromosomes so one of those chromosomes can compensate for any deficiencies in the other. On the other hand, males have only a single X chromosome without a “backup” x chromosome to make up for the faulty one.
