Color Vision Testing Made Easy (CVTME)

Help your child identify familiar pictures hidden in colored dots. This playful red-green vision self-check is not a diagnosis.

Why CVTME fits ages 3–5

Color Vision Testing Made Easy (CVTME) is a picture-based color blindness screening designed for young and pre-reading children. Instead of hidden numbers, each plate hides a simple object — a house, a dog, a boat, or a car — and the child points to the picture they see.

It screens for red-green color vision deficiency and is one of the most child-friendly tests available, validated for children as young as 3–5. This free online version generates fresh plates each time and is a self-check, not a diagnosis.

How the CVTME test works

1. Look at the picture

Each plate is a circle of colored dots with a picture hidden inside — a house, dog, boat, or car. A child with typical color vision spots it easily; a child with a red-green difference may see a different picture or none.

2. Tap what you see

Your child points to the matching picture (or you tap for them). No reading, letters, or numbers are involved, which is why CVTME works for pre-readers. Tap 'Nothing' if no picture stands out.

3. Get a parent-friendly result

We count which plates were missed to flag whether a red-green difference is likely. Because a home screen isn't calibrated and young children are harder to test, read the result as a screening hint, not a diagnosis.

What this test can and cannot tell you

  • Red-green screening. Flags whether a red-green color vision difference is likely present — the part to trust most.

  • Type is approximate. A red-weak versus green-weak hint is only a rough estimate, especially for a young child.

  • Not a complete color exam. This screen does not test blue-yellow vision or precisely measure the strength of a difference.

  • Confirm important results. For school or medical decisions, ask an eye-care professional to repeat the test with calibrated tools.

This is a free screening and self-assessment tool, not a medical diagnosis. Results are affected by your screen, its color settings, and room lighting.

Is the CVTME test right for your child?

It's designed for ages 3–5. Picture matching — a house, a dog, a boat, a car. No reading needed. Around age 3, a child may manage it with a grown-up's help; reliability climbs quickly from age 4.

CVTME — frequently asked questions

What is the CVTME test?

Color Vision Testing Made Easy (CVTME) is a pseudo-isochromatic color vision screening that hides pictures (house, dog, boat, car) and geometric shapes instead of numbers, so children who can't yet read can take it. It screens for red-green color vision deficiency and has been shown useful in children around 3–5 years old.

What age is CVTME for?

CVTME is aimed at young, pre-reading children — roughly ages 3 to 5. Most four-year-olds can complete it; at age 3 it's borderline and works best with a grown-up's help.

Does CVTME diagnose color blindness?

No. CVTME is a screening test — it flags whether a red-green difference is likely. A diagnosis, the exact type, and the degree need an eye-care professional with clinical equipment.
