So with this text based one you can point out what I am supposed to be seeing and then I can see it.
But for the normal ones, I have tried all the suggestions over the years that involved defocusing, looking at it cross-eyed, looking at it from certain angles, or from a certain distance, with my glasses off, etc. And even when you tell me what it is that I am supposed to be seeing, even when you take your finger and point it out to me, all I see is the noise.
