The visual standards required for whatch keeping mariners are laid down by IMO. They are tested frequently in our medical examinations through the use of the Ishiwara colour tests, a series of circes which contain different colour dots. Within the dots letters and or shapes appear. For a deck officer we have to take the Martin Lantern test prior to first going to sea and before sitting for each of our certificates of competency. The lantern test uses a single candle which shines through either a red, greeen or white lense in various combinations. The corect combination has to be seen. International standards are laid down by IMO. In the first instace for a deck officer no optical appliance is allowed to be used, later in life we are allowed to use spectacles. There are no requirements for visual standards for yachtsmen.
