Color Blindness in Children
It can become apparent that a child may be color blind when they begin to learn to distinguish colors. Between the ages of four and five, a child should be able to identify four colors. If your child cannot identify colors at this age, color blindness may be an issue, however there may be other causes to this delay, such as developmental issues.
If you suspect that your child may be color blind, there are a few questions that can help you determine whether he or she may be color blind:
- Can your child recognize pictures in books?
- Do other family members have color blindness?
- Can your child tell the primary colors apart?
If you believe your child may color blind, there are a number of tests that you can administer to determine whether your child is color blind or not. The most common form of color blindness is red green color blindness. Ask your child to pick out a red crayon in a group of crayons with orange, yellow and green. Then, ask your child to pick out the green crayon in a group with gray, white and brown.
There are several online versions of color blind tests that you can use to test your child’s color vision. Most of these online color vision tests are free and offer detailed explanations about results.
If you determine that your child is color blind, you may consider contacting an optometrist or ophthalmologist that specializes in color vision. A color vision specialist will be able to determine whether the cause of the color blindness is genetics, injury or another eye condition. If your child is given a definite diagnosis of color blindness, you should inform all of his teachers so that they are aware.
