Ishihara Color Test Instructions
Plates 1 – 17 each contain a number, while plates 18 – 24 contain one or two wiggly lines. To pass each test you must identify the correct number, or correctly trace the wiggly lines.
The Ishihara Color Test for Color Blindness
The test is used to identify which colors you are able to identify as well as calculate whether your vision is color deficient in any specific pattern. While the most common form of color blindness is red and green, this test is used to assess other, less common forms of color blindness and gauge the severity as well.
The Ishihara color test is used at our Long Island office to help patients who are seeking to start a career as a police officer, firefighter, or possibly even a pilot in the airforce.
