Picture this: your child brings home an art project and the trees are brown, the sky is orange, and the grass is a muddy grey. You laugh it off as creative flair — but could something else be going on? Color blindness in children is more common than most parents realize, affecting roughly 1 in 12 boys and 1 in 200 girls. 

At Garibaldi Eye Care, we help Sea to Sky families spot the signs early so kids can get the support they need in school and everyday life. Here’s what every Sea to Sky parent should know about color blindness — from the early warning signs to what happens during a screening

What Is Color Blindness in Children?

Color blindness — or color vision deficiency, as we call it in the clinic — doesn’t usually mean your child sees the world in black and white. Most children with the condition simply have difficulty distinguishing between certain colors, especially reds and greens, or less commonly, blues and yellows. It’s an inherited trait that’s passed along the X chromosome, which is why boys are affected far more often than girls.

The good news? Color blindness in children is not a disease, and it doesn’t affect overall vision or eye health. But it can create real frustration in the classroom if nobody knows it’s there. That’s why we always include a color vision screening as part of our comprehensive children’s eye exams at Garibaldi Eye Care.

What Are the Signs of Color Blindness in Kids?

Young children often don’t realize they see colors differently from their peers, so it’s up to parents and teachers to watch for the clues. Here are some common signs that may suggest a child has a color vision deficiency:

Coloring with unexpected shades. If your child consistently colors skin purple or uses dark greens where reds should be, it may not be artistic license.

Trouble with color-coded activities. Sorting games, math manipulatives, and color-by-number worksheets can become genuinely confusing for kids who can’t tell certain hues apart.

Difficulty identifying ripe fruit or reading colored text. A child might not see the difference between a red and green apple, or struggle to read instructions written in colored marker on a whiteboard.

Sensitivity to questions about color. Some children become anxious or avoidant when asked to name colors because they’ve been corrected before and don’t understand why.

If any of this sounds familiar, don’t worry — a pediatric eye exam can confirm whether color blindness is the cause and help you plan next steps.

How Is Color Blindness Diagnosed?

Testing for color vision deficiency is quick, painless, and something our team at Garibaldi Eye Care can do as part of a regular children’s eye exam. The most widely recognized test uses a series of dotted plates (called Ishihara plates) where numbers or shapes are hidden within patterns of colored dots. Children who have difficulty distinguishing specific colors won’t be able to see the hidden figures.

For younger children who aren’t yet comfortable with numbers, we use versions with simple paths or shapes — so even preschoolers can be assessed. Dr. Brandon Baker and Dr. Ashala Mah recommend that children have their first comprehensive eye exam by age three, and color vision screening can be included from that point on. Early identification means teachers and parents can adapt learning materials before any academic frustration sets in.

Can Color Blindness Be Treated?

Currently, there is no cure for inherited color vision deficiency. However, that doesn’t mean there’s nothing you can do. The most impactful step is simply knowing about it. Once you and your child’s teachers understand the condition, you can make small but meaningful adjustments:

Label colored items like markers, pencils, and paint tubes so your child can identify them without relying on hue alone.

Ask teachers to use patterns alongside color on charts, graphs, and assignments — stripes, dots, and crosshatching can replace color coding.

Use high-contrast text and avoid red-on-green or green-on-red combinations in study materials.

Consider specialty tinted lenses. While they don’t “cure” color blindness, some patients find that color-enhancing lenses improve their ability to differentiate colors in certain situations. Our optometrists can discuss whether these may be helpful for your child.

Why Early Eye Exams Matter for Sea to Sky Kids

Growing up in the Sea to Sky Corridor means your child’s world is full of color — from the bright greens of the Stawamus Chief trail in summer to the vivid fall foliage along the Squamish River. Color blindness in children doesn’t take those experiences away, but knowing about the condition helps your family navigate school, sports, and daily life with confidence.

At Garibaldi Eye Care, located in downtown Squamish near Save On Foods, we make children’s eye exams thorough and comfortable. From color vision testing and myopia management to general eye health checks, Dr. Baker and Dr. Mah are here to support your child’s vision at every stage.

Catching Color Blindness Early Makes a Difference

Color blindness in children is common, manageable, and nothing to fear — but early detection makes a real difference. If you’ve noticed any of the signs we described, or if your child is due for an eye exam, our team would love to help. A quick color vision screening can give you answers and peace of mind.
