THis may not be what you are looking for, but one of my eyes turns out. I wear glasses for myopia but nothing to correct the other condition except force of will. As I get older it is harder for me to keep my eyes focused together when I read (which is often) and sometimes I have to close one eye or it is just too distracting. I have not yet been prescribed bifocals,though.
On the plus side, I can see double whenever I want to, and make faces at my kids that they (b”H) can’t duplicate.
