11. Unfortunately, there is nothing that can be done once diagnosed with color blindness. Color blindness is a life long condition that can exclude people from certain jobs such as a pilot or a job that would include electronics. If you suspect colorblindness, you can visit an ophthalmologist or your health care provider. Being aware of the disease is the best way to help someone overcome this disease.
