Did you know color blind people are actually not blind at all? Rather color blindness is a deficiency in the way a person sees color, particularly colors such as blue and yellow or red and green. Most people who are considered color blind can see colors, but certain colors appear washed out and are easily confused with other colors, depending on the type of color vision deficiency they have.

Color blindness typically occurs when light-sensitive cells in the retina fail to respond to variations in wavelengths of light that enable us to see a variety of colors. Color blindness also can occur when aging processes damage retinal cells or if the brain suffers an injury in an area where vision processing takes place.

Although there is currently not a cure for color blindness, most people are able to adapt to their circumstances without too much trouble. Early detection and diagnosis of color vision deficiency may prevent problems during school years, particularly because many learning curriculums rely on color perception. Sudden or gradual loss of color vision can indicate any number of underlying health problems. If you start to develop color vision problems when you normally see a full range of color, it is recommended to visit your doctor.
