The D15 is a colour vision arrangement test that is done to see if a person has moderate or severe colour vision deficiency. It’s usually a requirement for jobs that demand high-level colour recognition for safety and accuracy, especially if they have failed the Ishihara plate test.
Some of these jobs may include: police officers/constables, Military personnel, firefighters, pilots, railway staff, employees of Transport Canada.
What happens during the test?
During the test, patients are asked to arrange a series of colored caps in order based on hue. This allows eye care professionals to identify patterns that may indicate specific types of color vision deficiencies.

The D15 test is used for:
- Detect red-green and blue-yellow color vision deficiencies
