Ishihara-style color vision test to detect color blindness or color vision deficiencies. Test your ability to distinguish between different colors and identify numbers or patterns in color plates. Useful for early detection of color vision problems.
Approximately 8% of men and 0.5% of women have some form of color vision deficiency. The most common type is red-green color blindness, affecting about 1 in 12 men. This test uses Ishihara plates, the same method used by optometrists and aviation authorities to test color vision.
