    Color Blindness, or Color Vision Deficiency, is an eye condition where a person is not able to distinguish certain colors or shades of colors to some degree. Color Blindness does not mean that a person can only see black and white. A person with color blindness is able to see different colors, however they are not able to see some colors due to deficiencies in the eyes. Color blindness is a hereditary condition but can also be caused by eye diseases, damage to the retina and macula, and aging or when the lens is darkened over time from a cataract. Although there is no absolute treatment for hereditary color blindness, there are methods, techniques, and special glasses that may help people with color blindness differentiate different colors but not truly see them.

    What causes Color Blindness?

    The retina contains rods and cones that help us to see objects in different colors and varying degrees of brightness. The cones are photoreceptors that allow us to distinguish between many colors and different shades of these colors as well. The cones contain light sensitive pigments that are particular to range of range of wavelengths. There are three different types of cones with one sensitive to short wavelengths, or the color blue, one sensitive to medium wavelengths, or the color green , and the other sensitive to higher wavelengths, or the color red . When there are deficiencies in the cones, either at birth or acquired through other ways, the cones are not able to distinguish the particular wavelengths and thus, that color range is seen differently. Missing the cones responsible for green and red hues can also affect the sensitivity to brightness. Color blindness is hereditary and thus it is usually transferred at birth. As we age our sensitivity also diminishes as well but usually not to a great extent. Damage to the retina from eye diseases or physical damage may also lead to color blindness.
