    They’re based on color blindness tests. They work because the background and the numbers appear to be the same color, making the number indistinguishable from the background if you have that specific kind of color blindness.

        Do you mean a simple audio or visual test that will test for diseases/ailments other than audio/visual issues? I’m not aware of any, and I doubt they exist. I’m not an expert though. I feel like most of the things mentioned in the meme don’t need a test, imo? Like as long as you’re in touch with your body and pay attention to what you intake these maladies should be easy to differentiate between.
