People who have color vision deficiency typically lack one or more of the three cones that are sensitive to a particular wavelength is the true statement.
Color vision deficiency is the inability to distinguish certain shades of color. Color blindness is used to describe this visual condition, but very few people are completely color blind.
Color vision is possible due to photoreceptors in the retina of the eye known as cones. These cones have light-sensitive pigments that enable us to recognize color.
Each cone is sensitive to either red, green or blue light. The cones recognize these lights based on their wavelengths.
The pigments inside the cones register different colors and send that information through the optic nerve to the brain.
Most people with color vision deficiency can see colors. The most common form of color deficiency is red-green. It does not mean people with this deficiency cannot see these colors altogether, they simply have a harder time differentiating between them, which can depend on the darkness or lightness of the colors.
Another form of color deficiency is blue-yellow. It is a rarer and more severe form of color vision loss than just red-green deficiency as people with blue-yellow deficiency frequently have red-green blindness, too. In both cases, people with color-vision deficiency often see neutral or gray areas where color should appear.
