About Color Blindness and Vision Testing
Color blindness, also known as color vision deficiency, affects approximately 8% of men and 0.5% of women worldwide. Our online color blind test uses scientifically validated Ishihara test plates to help identify the most common types of color vision deficiencies, including red-green color blindness (deuteranopia and protanopia) and blue-yellow color blindness (tritanopia).

Types of Color Blindness We Test For
- Deuteranopia: Difficulty distinguishing between red and green colors (most common type)
- Protanopia: Reduced sensitivity to red light, affecting red-green color perception
- Tritanopia: Rare condition affecting blue-yellow color discrimination
- Monochromacy: Complete color blindness (extremely rare)
How the Color Blind Test Works
Our test presents you with a series of circular plates containing colored dots arranged in specific patterns. Each plate contains numbers or shapes that are visible to people with normal color vision but may be difficult or impossible to see for those with color vision deficiencies.
The test evaluates your ability to:
- Distinguish between different hues and saturations
- Identify numbers and shapes within colored dot patterns
- Differentiate between similar colors in the red-green spectrum
- Recognize patterns that may be invisible to color blind individuals
Important Considerations
Disclaimer: This online color blind test is designed for screening purposes only and should not replace professional medical diagnosis. If you suspect you have color vision deficiency, please consult with an eye care professional for comprehensive testing and evaluation.
Factors that may affect test accuracy include monitor calibration, ambient lighting conditions, and screen quality. For the most accurate results, take the test in good lighting conditions on a properly calibrated display.
