Color blindness is a common condition where there is a reduced ability to distinguish between certain colors. It is either acquired or inherited, where as the majority of color vision deficiency is inherited.  There three main types of color blindness, In the first, the person has trouble telling the difference between red and green. In the second, the person has difficulty telling yellow and blue apart. The third type is called achromatopsia. A person with this form cannot perceive any colors at all; everything appears gray. Achromatopsia is much more rare than the first two types. Color blindness is more common in men. Women are more likely to carry the defective chromosome responsible for passing on color blindness, but men are more likely to inherit the condition. According to the American Optometric Association, nearly eight percent of white males are born with color deficiency, in comparison to 0.5 percent of women. While it may limit certain daily activities and work related tasks, most people find ways to adjust to the condition. For example, you might organize and label your clothing to avoid color clashes. Also some people use special lenses to enhance color perception, which are filters available in either contact lens or eyeglass lens form. Make sure you see your eye care practitioner for extra advice if you have difficulty distinguishing colors or if you have observed this difficulty in your child.
