Color blindness or color deficiency is the inability to see certain colors or sees colors differently than others. It is a genetic condition most commonly passed through the mother. It is caused by problems in the color-detecting nerve cells in the back of the eye. Color blindness usually affects males (1 in 12) but can also be found in females (1 in 200). My dad, uncle, and brother are all color blind. I knew that it was a high possibility that I was a carrier of the gene and my boys would have a high chance of being color blind as well.
My first question, how do you tell if a child is color blind? With older children and adults there are tests using numbers and pictures with different colors that can make it easier to see if there is something going on. But with children, it is much more difficult to diagnose. Often times it is not until children are around age 4 until they are able to developmentally distinguish different concepts including colors. One early sign might be using wrong colors to color certain objects like a purple sky or green faces. Because it runs in the family, I had suspicions when my son could identify letters, numbers, and shapes, but still struggled to identify colors. If you have concerns you can talk to your child’s pediatrician, have them go visit an optometrist, or in our case, our first visit was to the school nurse.
The most common type of color blindness is red/green color blindness, with blue/yellow as another. Still others cannot distinguish between shades or different colors or colors that are close in the color wheel such as shades of blue and green or pink and red-this is the case with my son. The most significant type of color blindness is achromatopsia in which someone cannot see any colors, only in shades of gray.
So what do we do? That was my next question. There is no cure for color blindness. There are special glasses you can get to help correct colors, but they come at a price. The best thing to do is just be aware and make some accommodations when necessary. Letting teachers know going forward and some children with color blindness may qualify for support with a 504 plan for accommodations. Even with considerations children who are color blind might have embarrassment, anxiety or frustration especially in school. Helpful tips for at home and at school
- Labeling paint, colored papers and other art supplies with the name of the color
- Making handouts of copies on white paper instead of colored paper
- Using a black marker on a whiteboard or a black marker on a white piece of paper
- Need more light in the classroom and seating accommodations
Even though there is no cure or treatment for color blindness, people who are color blind adapt very well to everyday life. If you have suspicions that your child is color blind, have a chat with your child’s pediatrician or other health care professional for next steps.
