Frequently Asked Questions
What is color blindness?
Color blindness is a hereditary visual defect where patients cannot normally distinguish certain colors, with red-green color blindness being the most common. This condition is usually caused by genetic mutations that affect the function of cone cells in the retina.
Is color blindness hereditary?
Yes, color blindness is an X-linked recessive genetic disease, mainly transmitted from mothers to sons. If the father is color blind, daughters will become carriers but usually do not exhibit color blindness symptoms.
What careers are affected by color blindness?
Many careers require accurate color vision test results, including pilots, ship operators, drivers, medical professionals, electricians, and chemical engineers. These professions often mandate Ishihara test screening or comprehensive color blindness tests. We recommend taking a professional color vision assessment before pursuing these career paths.
