6.10 Tests of colour vision

The Operational Colour Vision Assessment (OCVA) is undergoing a review. It is not currently accepted for colour vision deficiency testing. Applicants are asked to seek a Colour Assessment and Diagnosis (CAD) test in place of the OCVA. For further info please contact us.

Applicants for Class 1 or Class 2 medical certification who fail the Ishihara Pseudoisochromatic Plates (PIP) colour vision test are to be referred to a centre that conducts Farnsworth lantern (FALANT) or Optec 900 testing. Applicants for Class1 or Class 2 medical certification who fail the Farnsworth Lantern or Optec 900 test are to be referred for a computer-based Colour Assessment and Diagnosis (CAD) test.

Note: Colour vision testing for these applicants is to follow the sequence:

  1. Pseudoisochromatic plates (Ishihara PIP)
  2. Farnsworth lantern test (FALANT) or Optec 900 test
  3. Colour Assessment and Diagnosis (CAD) test.

A pass on any of these tests will satisfy the requirements for issue of an unrestricted Class 1 or Class 2 medical certificate.

New applicants for Class 3 medical certification are required to pass the Ishihara PIP colour vision test. No additional or alternative colour vision testing is available for this group.
