COLOR BLINDNESS is the inability to differentiate certain colors. It comes in various flavours with the most common being red green color blindness. There are multiple causes, but color blindness is primarily inherited by way of a mutated X Chromosome. Due to the fact that men only have one X chromosome, if they are handed a faulty X chromosome (by a carrier mother) they will be color blind. Women on the other hand have two X chromosomes, which is why many less women are color blind than men.  The odds that both X chromosomes are faulty is extremely low, and the healthy one will take precedence providing normal perception of color. Being color blind is officially considered a disability, however there have been studies docu*enting certain advantages including penetrating some camouflages. For instance – it was found during World War II that an*lysis of aerial photos yielded better results if at least one member of the surveillance team was color blind. It has also been suggested that females with one mutated X chromosome may be afforded an extra dimension of color awareness as they may have at least four types of cones in their eyes rather than two. Color Blindness is most commonly the result of hereditary reception of a genetically defective X chromosome. The chromosome usually comes from a carrier mother, and has a 50% chance of being pas*ed to her son. A daughter of the same mother will have a 50% chance of also becoming a carrier, and is only likely at risk of becoming color blind if the father is color blind. Color blindness can also be caused by accidents and other head trauma where permanent damage to the eyes occurs. This can happen as a baby (Shaken Baby Syndrome), or also later in life. UV Rays also present a risk of becoming color blind; they are in fact the leading cause of The 3rd way to get color blindness is through other hereditary diseases such as Diabetes. The list of diseases is long, and you can see the full list on the ‘Causes’ Page in the menu to the left. It should be noted that the amount of docu*ented cases on these illnesses
