What is a Color Blind Test?

A color blind test measures your ability to discern different colors, or determine color deficiencies. The Ishihara test is the most used, and the method shows phantom numbers within colored dots arranged in patterns or a circular shape.

People with typical color vision can readily identify a number, and color blind individuals may see a different number or the number may not appear to them at all.

Your test measures the digital recreation of all Ishihara-style plates.

Frequently Asked Questions

In our test, we use color plates like those used in color vision testing. However, testing conditions like screen position, brightness, and glare can affect test results.

Certainly. Our test is compatible with phones, tablets, and computers. However, for maximum accuracy, we recommend taking the test on a device with superior brightness and color quality.

Users spend an average of 1 minute or less taking the color blind test.

While there is no treatment to permanently cure color blindness, there are special filters and aids available to help some individuals see and differentiate between colors better.
