How to Identify Color Blindness in Children

Contrary to popular belief, a child who is color-blind doesn't see only shades of black and white. Instead, certain colors merely resemble each other. While children with normal vision can easily tell the difference between tan and green, for example, color-blind children see no distinction between these colors. Because color blindness is usually related with certain colors, it can go unnoticed for years, especially in younger children. If you believe your child may be color-blind, there are some signs to look for.

  Watch for signs of difficulty when the child is learning colors. Children as young as 2 should be able to match colors when asked. Many children who are color-blind can see most colors but struggle with a select few. Children who are green-weak confuse red and green, while children who are red-weak confuse purple and blue. Children who are quick to learn some colors but slow to learn others might be showing signs of color blindness.

  Check for color blindness in the parents of the child. Color blindness is almost always inherited and boys are at a much higher risk for inheriting it. Fathers pass on the gene to their daughters, though they may not always be affected. Mothers who are color-blind pass on the gene to all their children, regardless of gender.

  Test the child for color blindness at home. Several websites offer tests for color blindness. Some show a set of dots with a number or picture camouflaged within. Children with normal vision should easily identify the number or picture, but children who are color-blind will see only the dots, not the number or picture. Among other websites, the Archimedes' Lab website offers the test. Search online for the website by using such keywords as "Archimedes' Lab" and "color-blind test."

  Ask your pediatrician to test your daughter for color blindness. These tests are inexpensive and can be done on children as young as 3. After the test, your pediatrician will be able to confirm whether she is color-blind. If she is, your pediatrician can tell you which type of color deficiency she may have.
