Period

Canada

Until 1978, Ishihara's colour plates test was used by Air Canada to assess prospective pilots' visual acuity. See Ref #2 for an example of how this test was used. The Air-Canada standard for colour vision outlined by Dr. Antoine St.Pierre, director for eastern area of medical services in Air Canada, included the Ishihara colour plates test until 1978. This became relevant during a hearing before the Human Rights Tribunal appointed under Section 39 of the Canadian Human Rights Act. Donald Bicknell's pilot application was rejected by Air Canada partially because of his failure of the test, since his colour vision defect could be a safety hazard.

Function

Used to test for colour-blindness.

Technical

Developed by S. Ishihara, this test provides a quick and accurate assessment of congenital colour vision deficiencies.
