In general, there is no way to prevent color blindness. Regular eye exams and prompt treatment of eye disorders may help prevent some cases of color blindness.
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. Genetic counseling may be helpful to families with a history of color blindness.
