Ishihara Test for Color Blindness Detection

An Ishihara plate is shown, a standard method for assessing color vision. Individuals with typical color perception can clearly discern the number 2, composed of green dots, against the surrounding background of red and pink dots. It helps in detecting specific color vision deficiencies, particularly red-green blindness.
