Could pinhole glasses help me with getting better photofocus? Does anyone use them, are they effective?

I have a problem whereby one of my eyes is more powerful than the other thus the blip page is always slightly to one side, could pinhole glasses clear up this problem.

I have the same problem. I've just ignored it. When I started focusing on the outer edges of each page (white space) instead of focusing on the inner spine of the book, it seemed to become less of an issue.

Don't worry about the blip page being off a little...

My blip is hardly perfect but it has never concerned me.
