Colour vision restrictions for driving: an evidence-based perspective on regulations in ASEAN countries compared to other countries

“…The United Kingdom Civil Aviation Authority employed the Colour Assessment and Diagnosis (CAD) test to establish new minimum colour vision requirements for professional aviation pilots. 67 The CAD test uses moving colour signals to accurately measure red-green and yellow-blue threshold sensitivities, assess the class with high specificity and estimate the severity of colour vision deficiency. Also, CAD test also checks whether the colour deficiency qualifies the minimum requirements to perform the most safety-critical task.…”

Color vision restrictions for medical school admission: a discussion on regulations in ASEAN countries compared to countries across the world

“…For example, color vision categories proposed by Barbur et al range from ‘Supernormal’ trichromatic color vision (CV0), ‘Normal’ trichromatic color vision (CV1), ‘Functionally normal’ trichromatic color vision (CV2), ‘Safe’ trichromatic color vision (CV3), ‘Poor’ red-green color vision (CV4) and ‘Severe red-green color deficiency (CV5); and ‘Supernormal’, ‘Normal’ and ‘Acquired color deficiency’ for yellow-blue color vision deficiency. 22% of deutans and 1% of protans were classified as ‘Safe’ or ‘Functionally normal’ under this system [ 5 ]. Similarly, the Color Assessment and Diagnosis (CAD) test was developed to establish the minimum requirements to carry out the most safety–critical task.…”

“…Similarly, the Color Assessment and Diagnosis (CAD) test was developed to establish the minimum requirements to carry out the most safety–critical task. The CAD test has been adopted in other fields like the United Kingdom Civil Aviation Authority for professional aviation pilots [ 5 ] and the Transport for London for underground train captains [ 21 ], where about one-third of applicants, who would otherwise be rejected under conventional tests, were now considered safe. These efforts highlight the need to further validate the use of these tests to redefine color vision requirements in the medical field and its sub-specialties, to potentially minimize unnecessary discrimination against color-deficient individuals who can fulfill these tasks safely.…”

Evaluation of Visual Function Requirements for Public Jobs in Saudi Arabia

“…One such case was the mandatory introduction of color discrimination testing for marine watch keepers, train drivers, and other monitoring position at the 19 th century. This was established because of two fatal accidents attributed to inherited red-green (RG) deficiency [7], [8], [9]. In 1919, the International Civil Air Navigation Authority (ICAN) established color vision standards for the aviation industry, and nearly in 1930, color vision standards were used for road transportation in the United Kingdom [10], [11], [12].…”
