Approximately 8% of males & 0.4% of females are classified as having defective colour vision and should not work in jobs where good colour vision is required.


Ishihara tests may be used to screen for colour deficiencies.

The Farnsworth - Munsell Hundred Hue test gives a diagnostic evaluation of colour discrimination.


ICS offers to carry out on site Vision Tests with the deliverable being a certificate of the results for each observer. Tests should be carried out annually.
