El libro no tiene información de nada. Las laminas no corresponden a la prueba de Ishihara.

Ni las láminas son las originales del test, ni calidad de color, ni vale para hacer la prueba.

I don't know how this book has any favourable reviews as it is completely fake. This book contains pseudoisochromatic plates, but they are not at all Ishihara plates. Maybe the author thought that Ishihara is a generic name, but it is not. The book doesn't even offer a test or diagnosis, because there is NO rubrik or any sort of grading or instructions. So what can it diagnose? Worst of all, as a strong protan (a form of colorblindness), I was able to read all but one of the numbers because either the printing was severely botched, or the author literally just made up colors. Amazon should be embarrassed that they published this. This is not an Ishihara test is so many ways. Completely Fake.

I bought this color blindness book so that I can check on different days to see if my color vision changes from day to day. It does by a little, but I haven't figured out yet what makes for a good or bad day for color vision. Working on it.
