If you have employees whose colour vision is important for safety critical purposes then colour vision testing is crucial in deciding on their fitness for work. If colour vision needs in your business are associated with product quality then colour vision testing is valuable to avoid costly errors.

This guidance provides general information on colour vision tests for managers and others who may need to use them, such as occupational health advisers.

It includes a flow chart to help you design appropriate strategies for identifying, classifying and grading colour vision deficiencies.

Topics covered include colour vision assessment, coding, and testing policy, and the section on examination suggests situations where the different tests (Ishihara plate test, City University test, and the lantern test) may be appropriate.
