Colour vision - SODA in Australia
Hi guys,
I have failed the Ischihara & Farnsworth tests, and the next (and final I believe) step is to go out to the airport & identify colours from the tower light gun. 3 lights at 300m and 3 lights at 500m apparently, not allowed to get any incorrect.
I believe this is done in the US as well as Australia, and not sure what other places.
My question: what is the best time of day to do this test?
1. Bright sunny day
2. Dull cloudy day
3. Night
Any further information on this test would be most appreciated.
Cheers
