Colour Blindness

After finding it difficult to find out just what jobs are off limits to colour blind sufferers I decided to create a page to help. Having red in green colour blindness myself I know that this is only important to people/companies when they find out you are colour blind and they can discount you. They're not concerned about helping sufferers beforehand.

What jobs can't you do if you are colour blind?

Working on ships

There is a colour vision test for seamen, this is to make sure they can differentiate red and green. This is the most common form of colour blindness, it affects about 5% of males.

Ship deck staff have to be able to differentiate red and green so they can identify the port and starboard lights on a ship and as such tell which way the ship is travelling.

Working in the engine department of a ship does require being able to tell the difference between red and green as in electrical wiring and cabling as well as the red and green water pipes and valves.

If you fail the Ishihara test you can get a restriction placed on your certificate limiting what you can work on but this will greatly reduce your chances of getting employed.

There are coloured lenses for contacts and glasses that help you adjust how you see red. These will allow you to pass an Ishihara test when colour blind but may affect how you see other colours.

If you work in the catering department of a ship then it doesn't matter if you are colour blind or not.
