Color+Blindness-Description

=**Description of Color Blindness**=

Color blindness occurs when there is a problem with the color-sensing granules (pigments) in certain nerve cells of the eye. These cells are called cones. They are found in the retina, the light-sensitive layer of tissue that lines the back of the eye inability to see certain colors in the usual way. The name for when you can't see any colors at all is Achromatopisia.

The first case of colorblindness was described in the late 18th century by chemist John Dalton, who was himself blind. Dalton is more commonly known for developing the atomic theory, but the first paper he ever wrote described colorblindness in himself and his brother. His research started the ball rolling on this condition in the scientific community, and today, some call colorblindness Daltonism in honor of his first description.
