In grade 6, an adult came in to class to do a colourblind test on everyone.
Projection screen was lowered, lights turned off, and a series of multi-coloured dots on many slides were displayed one after another on the screen.
In the dots, there were numbers / letters in colours different from the general background colour of the slide.
Adult: "Can everyone see the number?"
Almost everyone: "YESSSSSS."
One boy: "Ummm - there's no number on the screen!"
Pregnant pause.
One boy: "Oh yeah. Now I see it."
Almost everyone turns their head to look at that one boy.
Test continues.
Afterwards, the one boy was selected for further consultation...
It really should be a part of general screening upon admittance to primary school. Then again, this was 30 years ago, so maybe it is now.
