What is the new vision test involving yellow and black squares called?

Question

For my medicals, the vision acuity portion was accomplished by looking into a microsope-looking device that projected squares with patterns in them and I had to identify which corner had the differing pattern. Anybody know the name of this new test?

Sounds like a color blindness test to me.

Back when I had my last medical I had to look at what appeared to be a baby book, you know they ones with thick *** card board pages.  Like a 10 page booklet is 2 inches thick.  Anyways they said 'what number do you see' and there were yellow dots with a slightly different colored dots making a number.  Or green, blue red whatever.  Anyways that was for color blindness.  I still dont know amidoinitrite with those but I passed so I suppose something went ok.

It sounds like a fancy, modern, color blindness test

If it's a flickering pattern of gray squares and you have to identify the direction of a few colored squares, it's probably the new color vision test being used in a number of countries, notably the U.K. (from what I've been told). It's called the Colour Assessment and Diagnostic Test (CAD). It's extremely good at identifying people with color blindness, and it is very accurate for determining how bad their color blindness is and what type it is.

I just took my class 2 and don't recall that test. I just had to identify the numbers in the circle filled with multicolored dots.
