Everyone keeps saying to go cross eye or to do all these tricks but I see the image at a glance and it's much simpler and less painful with one trick. Treat it like a window.

The whole point is that you are trying to defocis yours eyes so the image overlaps on itself and makes the image inside it stand out. You can try practicing on other things like a mirror or a screen door or window before looking at these where you focus not on the screen itself or the mirror itself but past it.

If you can trick yourself into just looking into the image like it's behind a window and just casually let your eyes defocus and look for a shape in the mess then you can fixate on it and see the image.

I think it's definitely better than straining to try and see it.
