Caucasian Boys Most Prone to Color Blindness, Study Finds04/04/14
THURSDAY, April 3, 2014 (HealthDay News) -- Caucasian boys are
the most likely to be color blind, while the risk is lowest in
African-American boys, a new study finds.
The researchers also confirmed that girls are much less likely
to be color blind, which is an inability to see colors accurately.
The most common form of the condition involves a genetic mutation
that makes it hard to distinguish the color red from the color
Researchers tested more than 4,000 preschoolers, aged 3 to 6, in
California and found that 5.6 percent of Caucasian boys were color
blind, compared with 3.1 percent of Asian boys, 2.6 percent of
Hispanic boys, and 1.4 percent of African-American boys.
Among girls, rates of color blindness ranged from 0 percent to
0.5 percent among different racial/ethnic groups, according to the
study published online April 3 in the journal
The researchers also concluded that screening for color
blindness can begin at age 4. Testing for the condition at an early
age is important because children with color blindness often do
poorly on tests or assignments that feature color-coded
"It's not that the child is not smart enough or bright enough, it's that they see the world a little differently," lead investigator Dr. Rohit Varma, chairman of the department of ophthalmology at the University of Southern California (USC) School of Medicine and director of the USC Eye Institute, said in a journal news release.
Children with color blindness require different types of lesson
plans that don't require the ability to see colors correctly.
"That needs to start early on because labeling a child as not smart or bright enough is a huge stigma for the child and causes significant anxiety for the parents and family," Varma said.
