Please summarize the causes and cure for color blindness given in the passage?
The most common cause of color blindness is genetic disorder. Males are more likely to be color blind than females, because the genes responsible for the same are present on the X chromosome. Females who are non-color blind could still carry and pass on genes for color blindness. Any kind of physical or chemical damage to the eye, optic nerve or brain could also lead to the same.

There is no cure for color blindness. Affected people can actively accommodate the condition or use special glasses or lenses that can help people with red-green color blindness to a certain extent. There are mobile apps available as well to help identify colors.
