If someone has Color Blindness they are often called Color Blind or said to have Color Blind Deficiency. If you have colorblindness you have a defect in your vision that makes it hard to tell certain colors appart. It is usually passed on genetically by the mother. You can also get Color Blindness from other eye diseases, certain medications such as hydroxychloroquine (Plaquenil), or by just getting old. You can get Color Blindness when your get older because your clear eye lens can get darker over time and lead to difficulty seeing dark colors. The approximate percentage of having Color Blindness is 8% in males and 1% in females. It is a sex-linked characteristic and there is no cure for it. But there is tinted eye glasses that can help people tell colors apart. The gene that is altered in the disorder is the X chromosome. Which is given from the mother to the child. The Y chromosome, that is passed on by the father to the child, has no defective gene. So children inherit color blindness only from their mothers.

Your retina is a layer of tissue in the back of your eye that is light-sensitve. When these molecules are not present some colors in the spectrum cannot sex-linked characteristic. Color Blindness is not anywhere near life threatening and not threatening at all and is common. Some people think that if someone is color blind that they only see black and white.
