Color Blindness

Color Blindness

Color blindness is often a color vision problem. Color blindness is mostly genetically inherited. In other cases, the following factors may also cause color blindness: aging, eye injury, glaucoma, cataracts, macular degeneration or diabetic retinopathy.

An eye has three types of cone cells - each type respectively detects red, green, or blue light. Most cone cells are located in the macula - the central part of the retina. If these cone cells function properly, the eye will be able to recognize different colors.

Genetic color blindness usually can not be cured. However, if the problem is due to cataracts, cataract surgery may be used to remove the cataracts, and thus restore color vision.
