Colour VISION ASSESSMENT
Suffering from colour vision impairment?
Does your occupation or trade depend on you being able to see or distinguish between specific colours? Have you been told you are “colour blind” because of failing one CV test? David has a variety of different colour blind tests (colour vision tests) that he can conduct to determine the nature of your condition.
Colour blindness can refer to two different conditions affecting a persons’ ability to see colour. Monochromacy, where a person sees a very limited range of colour is extremely rare and affects approximately 0.00001% of the population. However, Colour Vision Deficiency (CVD) is more common & affects approximately 8% of men and 0.1% of women. They are not Colour blind, they can see colours, but may confuse colours or miss slight colour change depending on their level of severity.
We boast one of the most extensive ranges of colour vision testing equipment available in Perth. Performing a wide range of tests allows us to properly advise you on how your colour vision complies with the various industry groups including Aviation, Mining, Electrical, Rail Transport, Maritime and the Australian Defence Force.
David tests the colour vision of many aspiring pilots or air traffic controllers as part of his Aviation Eye Test. He has a variety of colour blind tests he can conduct to suit the patients needs. David is certified by The Civil Aviation Safety Authority (CASA) to conduct testing and submits the results to CASA directly.
