OPHTHALMOLOGY (Manual of Civil Aviation Medicine)[c) Beyne´s protocol

Ambient lighting: DarknessAdaptation period: Three minutesVisual correction: Normal distance - (non-tinted)Subject-lantern distance: Five metres (subject is seated); lantern is at eye levelLantern setting: Three minutes of arcExposure time for each light: One secondPermitted response time: Three seconds (from the termination of light exposure)

Pre-test instructions:This test is to find out if you can distinguish red, green, white, blue and orange

lights.The lights will be shown to you one at a time. You will see red, green, white, orange and blue and no other colours. You will be shown each light for one second and will have three seconds to respond. If you take longer than three seconds, this will be regarded as a mistake. Any questions? Start now’The lights are not demonstrated prior to the test.

Order of presentation of the lights:First and last presentation is blue. Between the two blue presentations three white, three green, three red and one orange light are shown, in arandom order i.e. 12 lights are presented.

Number of runs: One (two if one mistake is made in the first run)

Pass criteria: No mistakes - the subject is passed as ‘colour vision safe’.Two or more mistakes - the subject is failed as ‘colour vision unsafe’.Only one mistake - a second run of 12 lights is permitted. If no mistakes are made on the second run, the subject is passed as ‘colour vision safe’.

The lantern-tests may be retaken after 6 months.
