Colour blindness test
You stand at about 3 meters from a circle with various points of different sizes and colours. The instructor indicates a point and you have to say the colour. In some cases they ask you to close one eye, so it can be tricky, especially for the smallest points. But the test is just to check if you are colour-blind, not to measure your acuteness of vision, so it doesn’t matter if you fail a few times.
Reaction time test
You sit on a chair with 2 pedals on the floor. One represents the accelerator and the other is the brake. In front of you there is a green light, and all you have to do is brake when the light turns red, then use the acceleratir pedal when the light turns green. Very easy!
Depth perception test
Basically you have to align a moving pin with a fixed one, by using forward and back buttons. In Bangkok you will have to pass this test, but not all provincial offices are equipped with this machine.
