Colour vision assessments are conducted in the colour vision clinic for congenital and acquired colour vision deficiencies. 


Congenital colour vision deficiencies affect approximately 8% of males and 0.5% of females. 

Congenital colour vision deficiencies are genetic (the colour vision gene is carried on the X-chromosome) and are generally stable throughout life. Acquired colour vision deficiencies are not genetic and may result from illness, an eye disease or occur as a side effect of medication. The severity of the colour vision deficiency may change with time. A detailed referral is required if an assessment is requested regarding an acquired colour vision deficiency. If this is not available, we can arrange an appointment for a primary care consultation before being seen at the Colour Vision Clinic. 

At the UNSW Colour Vision Clinic, optometrists can measure the type and, depending on the client’s age, the extent of colour vision deficiencies. Once this information is known, clients can discuss with the optometrist the occupational and practical consequences of their colour vision. 

Examinations to assess the suitability of clients with normal colour vision for tasks requiring precise colour discrimination, for example colour matching and quality control work can also be requested.  

Reports of colour vision assessments to vocational bodies can be provided on request.
