Color Blindness | Symptoms & Signs | Diagnosis & Tests | Prevention & Expectations | Treatment & Monitoring

How is the condition diagnosed?

Color blindness is usually self-diagnosed. Achromatopsia may not be uncovered until a child is 3 to 5 years old. To confirm the self-diagnosis, the healthcare provider usually performs a color test. Common tests include the HRR pseudoisochromatic plates or the Ishihara plates. The diagnosis of achromatopsia is sometimes determined by performing an electric eye test. This test is called an electroretinograph.
