Color blindness, also known as color vision deficiency, is the decreased ability to see color or differences in color. Color blindness can make some of you educational and life activities difficult. Buying fruit, picking clothing, and reading traffic lights can also be challenging.
The most common cause of color blindness is due to a fault in the development of one or more of the three sets of color sensing cones in the eye. Males are more likely to be color blind than females. Color blindness can also result from physical or chemical damage to the eye, optic nerve, or parts of the brain.
There is no cure for color blindness. Special lenses may help people with red-green color blindness when under bright conditions. There are also mobile apps that can help people identify colors.
