Color Blindness

Color blindness is the inability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals.

Symptoms: The reduced ability to tell certain colors apart.

Cause: There are six million cones in each retina which provide detailed and color vision. There are three types of these cone cells, one is sensitive to blue light, another to green, and the third to red light. If one or more of these three types of cones are faulty, color blindness results. In one type of inherited color blindness, a color-blind father passes his recessive genes on to his daughters who are not color blind. But their sons may inherit color blindness. In another type, both males and females can inherit it equally.

Other cause include macular degeneration and several other eye disorders. The toxic effects of various drugs, including chloroquine (used for malaria) can also cause it. If the condition is caused by eye diseases or drugs, the color blindness can be alieviated to some extent.

Natural remedies for color blindness:

  • Take 5,000 units of vitamin A daily and 25,000 IU of carotene.
