Etymology: "Tritanopias" is simply the plural of "tritanopia," a visual condition in which the eye's short-wavelength (blue-sensitive) cone cells do not respond properly, so blues can look grayish or hard to tell apart from other colors. The plural is used when discussing more than one case or type of this condition. The main term is built from three Greek elements. "Trito-" means "third," referring to the third type of cone in the retina, the one sensitive to short wavelengths, which is the least common of the three. "An-" means "without," and "-opia" comes from the Greek "ops," meaning "eye" or "vision," the same root found in words like "myopia" and "presbyopia." Put together, the name describes a deficiency in the third color-sensing system.
