Rates: Occurrence is the number used to show how many new cases of something are diagnosed per year. Prevalence is the number of actual cases of the diagnosed condition present at any one time. Approximately 1 in every 75 people have a diagnosis of "color blindness.".

About 8%: The standard statistics for inherited color deficiency is about 7.5% in males and 1/2 % in females. This can vary somewhat with different racial groups. The degree of color deficiency and the type are variable so your ophthalmologist can test you and see in which category you are if that is important to you and also give you information about your family possibilities.
