3D movies don't work for me

Are you able to see 3D Stereograms?

I remember first being introduced to the concept when I was about 8-years-old. It took me a while to see it the first time (20 min+). But, after that, I was able to get them immediately, even after 20+ years of not seeing one. Maybe it’s something you have to train your eyes and brain to see, perhaps a form of muscle memory?

It could be convergence or eye dominance according to this article.

I can usually do them when I’m told what I’m supposed to see. Then, I can see it without really trying. I think it could be an eye dominance issue. It was mentioned by the optometrist when I got my current pair of glasses that one eye seemed dominant. It surprised me that no one caught it in the decades I’ve been wearing glasses.
