Deuteranopia (noun)
dew-te-ran-oh-pee-a
a defect of vision in which the retina fails to respond to the color green.
Deuteranopia is formed from Ancient Greek deúteros, meaning “second,” and English anopia, “absence of sight.” Red, green, and blue are the three primary colors of light, and deuteranopia gets its name because green is considered the second of these colors. Deuteranopia was first recorded in English at the turn of the 20th century.
