Color Blindness is a condition typically present from birth, that prevents or alters the ability to see color in a variety of ways. While color blindness may block one from seeing color entirely, most people who experience color blindness simply have trouble with specific pigments. Most people who experience color blindness have difficulty deciphering one color from the other. For example, they may have trouble telling the difference between red and blue, but can see orange and green without any problems. While color blindness doesn’t pose serious risks to one’s health, it can make some daily tasks more difficult, especially those which rely on color defined traits.
Causes of Color Blindness
Color blindness is typically caused by genetic factors, but on rare occasion may manifest itself due to aging, or serious eye disease such as diabetic retinopathy, glaucoma, or cataracts. Genetic color blindness ususally results from certain photo-receptor cells in the eye (cones) lacking the ability to pick up either red, blue, or yellow.
Color Blindness Treatments
Currently, there are not any known treatments for color blindness. Certain colored lenses or shaded sunglasses may help people with color blindness decipher colors better. Most of the time, people who experience color blindness learn to rely on other ways to determine colors from each other such as social cues that suggest one color over another.
Color Blindness Symptoms
Many who grow up with color blindness do not initially realize they are color blind until they start confusing colors that are readily obvious to others. Most who are color blind see enough colors where they are unaware that they can’t decipher a third color.
Symptoms of color blindness usually show themselves when children mix up learning colors in early grade school. Color tests can be performed to further diagnose color blindness for all individuals.
