Disclaimer: I'm not a doctor or anything, just a guy that have some serious headache whenever his eyes diverge.
Those exercises are meant to avoid your eyes to diverge, and since they are stereograms, you should cross your eyes so that the left and right part of the image form a third image at the center you should look at.
You should maintain and stabilize that image until your vision is sharp and clean, and you can move around (slowly) the image without losing focus. It could take a few seconds or more if you are not familiar with stereograms.
Be careful, while doing so, the image and your eyes MUST BE perfectly horizontal, or instead of correcting your eyes axis, you could make it worse.
Once the third image is stable, look at every part of it. If there is a text, read it. Some stereograms have perspective/3D-like effects (some parts looks closer, some parts looks further). Some requires you to cross your eyes more or less. Some have missing parts on the left and on the right part, and are intended to force your brain to use both eyes to recompose the image, not your stronger eye only.
When my eyes maintain a good focus, I move the image back and forth, up and down, left and right.
I hope it will help you, Take care.
Can someone identify what to look for on each image. Without initial guidance it is very difficult to see for the people with weak eyesight.
