Colorblind Test

A color blindness test is a series of exams designed to determine if a person has difficulty distinguishing colors. The most common type of color blindness test is the Ishihara color test, which involves a series of plates that contain circles made up of different colored dots.

The person being tested must identify the number or shape hidden within the dots. Other color blindness tests include the Farnsworth-Munsell 100 Hue test and the D-15 test, which also use colored plates to assess color vision deficiency.

These tests are used by optometrists and ophthalmologists to diagnose color blindness and to determine the extent and severity of the condition.
