Hello everyone, to begin please understand that I'm still am a student. So if this is a stupid question...
So, in taking an eye exam, have you ever hear of a red test?
You see, I'm trying to make my homework and encounter the following question: Conclude the eyeexam with a red-green test and a red test.
Now, I know the red-green test and the polarised red-green test but a "red test"?
The worst part is that no teachers at school can tell me what a red-test nor can any of my collegues at work.
Do any of you know what this so called red test is?
Thanks in advance,
Mactire
