Discuss the issue with your pediatrician.The dazzling experience of color begins when light strikes a canvas of tightly-packed nerve cells in the back of the eye.Encourage your child to let you know if they are experiencing difficulties related to their color blindness.Make sure crayons and markers have color names on them.Find out how teachers will help your child during exams or other times they need color awareness.You may need to do this yearly to make sure new teachers are aware.Inform your child’s teachers, including special area teachers (physical education, etc.) that your child is color blind and will need cues that are not based on colors.Ensure that your pediatrician tests your child for color blindness.All teachers should be aware of your child’s problems.īecause your child can not see colors the same way everyone else does, they likely won’t understand why they are being told they are incorrect. A physical education teacher may have red or green tops to identify teams. If your child cannot see the colors, a teacher may think they don’t know their colors or that they are not following directions.įor example, if a teacher uses colors on a smartboard or overhead projector to signify different stages in problem-solving, the color blind child will lose that part of the instruction. Games, color-by-number, and other activities use colors as part of the activity. The implications of this are far-reaching. They will struggle with differentiating certain colors and shades. In toddlers and preschool-age children, this will affect color identification. There are other, less common types of color blindness, such as monochromatism, dichromatism, and anomalous trichromatism, which your doctor can explain in detail.Īs you can see in the image above, a child with red-green color blindness (deuteranopia or protanopia) sees red as brownish-green, green almost the same as red, and blue and purple both look blue. Tritanopia makes it difficult to tell the difference between blue and green – and yellow and pink – and makes colors less bright. Protanopia makes red look less bright and more green. The most common is red-green color blindness. Your pediatrician can accurately assess color vision during an office visit. While you can perform a preliminary screening at home on a computer, the results will not be definitive due to variations in color representation.

Named after a Japanese ophthalmologist, the test consists of a series of circles containing patterns of seemingly random colored dots. The most widely used test for color blindness is the Ishihara Color Vision Test. About 8% of all men and 0.5% of all women are affected. It is important to note that men are much more likely than women to be color blind. Is he confused, or does he see no difference in the crayons? Deep blue and purple crayons look a lot alike. For example, a five-year-old boy may frequently mistake purple for blue or vice versa. It’s very difficult to identify color-blindness in young children because we can’t tell if they simply don’t know the name of a color, or there’s an issue with their vision. They then progress to green, purple, orange, and more. At preschool age (and earlier), they are routinely asked to identify red, yellow, and blue, the primary colors.

One of the early concepts we teach our children is color.
