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.
