That is one of the worst designed things I have ever seen. The instructions barely made sense at all for the first test, and for subsequent ones where you can enter 2 responses there is absolutely no indication what should be going on.

Wow, I was expecting this to be hyperbole but you’re right. No clue what you’re actually supposed to do on this site.

Yeah, I'm not sure what I did. But I went from question 1, to question 2, to question 2, then I saw a button saying "FINISH", so I clicked it and I got 12 answers wrong.

They're a site that sells goggles for the colorblind, so either way I wouldn't trust their colorblind diagnoses.

I’ve been in a lot of ophthalmologist’s offices for a variety of issues, and even had surgery as a child to correct one of them. The one issue I do not have is color blindness—and I’ve been given a lot of these tests.

This website doesn’t work on my iPhone’s screen. It’s impossible to discern most of the numbers, and the UI doesn’t instill confidence. Are they just using this garbage to hock their glasses to people who don’t need them?

This website is thoroughly broken, and nobody should even use it as a suggestion that they are or aren’t colorblind.

I think the numbers are visibles only if you have color blindness

That's right. maushu even said it's a reverse color blindness test. If you can't see any of the numbers, then you likely do not experience red-green color blindness.

It's a completely broken test. The "correct" answers at the end indicate two-digits numbers for "plates" when only a single-digit answer was possible.

I, without color-blindness, can't make out any numbers. A coworker who is red/green colorblind also could not make out any numbers. Then the results, as I said, show that the whole process was broken from the start.

I just took a test. I cannot see shit in color. Haha. Fuk! Do those glasses actually help reverse this? I can clearly see RGB. But some hues look the same. Are people born color blind or is this wear and tear kind of situation?

Ignore this test. It doesn’t work on a computer. You need to take in in-person using specially-printed images.

Maybe they don't work to rule it out, but I am colourblind (as diagnosed in-person with specially-printed images by a professional optician) and when people have pointed me at these images on computers (only slightly less annoying than 'can you see this?', 'what colour is my shirt?') they've always 'worked' as expected.

This particular website doesn’t work on a computer. I’ve seen others that work well enough. This website is just broken. I believe this version is intended to only be legible if you’re colorblind, but good luck actually using it.
