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.
Color blindness is a lifelong condition.
It's important to determine color blindness as early as possible. Individuals can be taught to cope with employment, hobbies, and games that require more exact color vision. Color blindness is not contagious, and poses no risk to others. It is an inherited trait in most cases. Children of a person with color blindness are more likely to develop the condition.
