Research proves that testing for color blindness as early as 4 can help children succeed in school.
Children with color vision deficiency may perform poorly on tests or other assignments. If the student and their parents are unaware of the issue, those students may struggle in class, leading teachers to group them in the wrong academic track at school.
Despite the name, color blindness is not a type of blindness, but an inability to see colors accurately. The most common form of color blindness is genetic and involves a mutation or lack of genes that help the eye see red or green. This genetic deficit is presenting 5 percent in males and 1 percent in females.
