The Ishihara Colour Blindness Test Cards are recognized globally as a simple and accurate method for detecting congenital color blindness, particularly red-green color blindness, in both complete and incomplete forms. The test includes four special plates designed to determine the type and severity of color vision deficiency. Using the unique visual effect where blue and yellow appear brighter than red and green for individuals with red-green blindness, the test provides a reliable diagnosis. The color plates are conveniently housed in album-type books for easy handling, and detailed instructions are included for accurate administration.
