General
Color blindness is a condition that affects the way people see colors. It is an inherited condition, more common in men. People who are color blind, cannot distinguish some colors, such as blue and yellow, or red and green, which is the most common form of the disease. Color vision defects may also be caused due to Parkinson’s disease, cataracts, certain medications, Leber’s hereditary optic neuropathy (LHON) and Kallman’s syndrome.
