Colour vision in the workplace

IET factfile: Health and Safety - Colour vision in the workplace

A factfile from by the IET

Approximately 1 in 12 men and 1 in 200 women suffer from some form of defective colour vision.

The degree of disability varies widely, and can even be so severe as to preclude an individual from pursuing certain careers.

Complete colour-blindness (i.e. the perception of the world in monochrome shades of grey), however, is very rare.

This fact sheet answers some of the common questions asked by people who think they may have some form of colour vision defect, as well as those asked by employers.

To maintain the safety of our members, volunteers, staff and everyone we work with, we have taken the decision to cancel or postpone ALL IET events until the end of June. We are monitoring the rapidly changing situation and will provide further updates when we have them.
