Color Vision & Contrast Check
Complete eight short color-and-contrast challenges. Your result is a screening performance score — not a measurement of eyesight or a medical diagnosis.
Important: Screen brightness, display settings, room lighting, color filters and your device can change the result. If colors are consistently hard to distinguish, an eye-care professional can perform validated color-vision testing.
Before you start
Set your screen to normal brightness, turn off night mode or color filters if possible, and view the screen in ordinary room light. Do not zoom the page.
